00:00Have you ever wondered what these extra holes at the top of your running shoes are for?
00:04They're designed so that you can tie the shoes in multiple different ways.
00:08That's useful when you want to compensate for things such as a bad stride or even a damaged toe.
00:15Plus you can change the look of your shoes the way you prefer.
00:21Many people use a dust jacket of their book as a bookmarker. No problem with that.
00:26It will save your book from bent page corners, but the primary purpose of a dust cover is to keep
00:32the book safe from distortions.
00:34For instance, if you spill juice or drop some of the food on your book while reading it.
00:40The Tic Tac dispenser has this little groove on its top, so you can dispense only one Tic Tac at
00:46a time.
00:47Even though, let's be honest here, nobody does that.
00:50Most of us just spill a whole bunch at once and then we wiggle all those extra Tic Tacs back
00:55in.
00:57Those rubber bumps you see between the tire treads are there for your safety.
01:01The raised edges tell you what the minimum height of your tread is.
01:05If the bump and the edges are even, it's time for you to visit the tire shop as soon as
01:10possible.
01:11But if the bumps are well beneath the level of the edges, you're good to go.
01:17What about that black grating on the microwave window?
01:20It's something called a Faraday shield.
01:23And it's there to prevent microwaves from getting away and turning the entire room into a Faraday cage.
01:29If the microwaves escape, your meal won't cook properly either.
01:33So yep, the cage is not there to make it difficult for you to see your meal while it's cooking.
01:37It's keeping the electromagnetic energy inside.
01:43How about a wrench compatible screwdriver?
01:45Cover your screwdriver with the end of your wrench and you can increase its torque.
01:49That's why the head of your screwdriver is designed the way it is.
01:53When you have odd angles, you can use this strategy.
01:58You've probably heard those myths, the blue side of the eraser can erase the pen.
02:03False.
02:04Its purpose is to erase a pencil.
02:06But in case you're writing something on heavier paper.
02:09The blue side can remove smudges you see after using the pink eraser too.
02:15Have you ever wondered why oranges in supermarkets mostly come in the red mesh bag?
02:21It's a trick to make this food look more orange and encourage you to make a purchase.
02:25An extra tip, don't throw away the mesh bag.
02:28Tie it up so you can have a small pot scrubber to clean your sink, kitchen, appliances and dishes.
02:37You can see golf balls don't have a perfectly round shape.
02:40Their surface is covered with many little dimples, something golf balls didn't always have.
02:45At one point, experienced golfers started noticing how through time, older balls with imperfections, such as nicks and bumps, could
02:54travel further.
02:56Such things create turbulence in the air around the golf ball, which eventually reduces drag.
03:02So, manufacturers started producing balls with dimples so they could go farther and faster.
03:10You might have noticed that sometimes there are ridges in toothpick tops.
03:13It's more hygienic because when you break that off, you can prop the toothpick up on it and it won't
03:19touch anything.
03:22Another safety feature you'll find, this time in your car, is a tab on your rearview mirror.
03:28With it, you can change the position of the mirror so you don't get blinded if there's a car behind
03:33you with its high beams on.
03:35So, this little tab helps you control the glare of lights coming from behind.
03:40This feature showed up in the 1930s, but in the early 1970s, it became a part of standard equipment in
03:46most trucks and cars.
03:49Do you see that tiny hole on your iPhone right next to the rear-facing camera?
03:54It's a microphone, and it's there so your phone can record sound as you turn your camera around.
04:02Some cables have a thick cylinder towards the end of the cord.
04:06It's called a ferrite core, or a choke.
04:09It's a magnetic iron oxide that stops high-frequency electromagnetic interference.
04:14For example, you know that annoying static noise you get if you bring your phone too close to a speaker?
04:21This interrupts your call, which is why cable cords with big cylinders are pretty useful, because they prevent these things.
04:29Do you know why nearly all luggage bags and backpacks have two zippers?
04:33It's way more convenient and easier to open in that way.
04:37But not just that.
04:38You can also lock these two zippers together to keep the stuff inside your bags safer.
04:45You know how toilets at public spots like malls have those big gaps at the bottom?
04:50It's primarily for better circulation of air.
04:53This type of door also makes it easier to clean the toilet or check if it's occupied if you're standing
04:59in line.
05:00Other than that, if you get stuck there and the lock gets broken, you still have a way to escape.
05:06You can just crawl out.
05:10Ever notice those plastic end caps on utility knives?
05:13And they also have scales on them, which indicates you may use them multiple times, but with sharp edges.
05:21You can separate the blades through these plastic end caps.
05:24Then, you can move the slider and bring the sharp blade to the front.
05:29If you've ever taken a moment to examine a regular grocery cart, especially their fold-out section, you probably noticed
05:36those metal loops jutting out.
05:38They're designed to protect the items you carry in your cart.
05:42You can use them to hang bags with soft items.
05:46You don't want to accidentally squish with heavier products, like bread, or easily breakable things, like eggs.
05:54Many coffee mugs come with curved notches on their bottom.
05:58When you're washing your mugs, put them against the rack at an angle in your dishwasher.
06:02This way, the water won't pool in there, so your favorite cup will be completely dry by the time you
06:07take it out of the dishwasher.
06:10If you're a McFlurry fan, you've probably noticed there's a square hole in the handle of the spoon.
06:16It's there so you can attach it to the special machine that mixes the ice cream and your favorite toppings
06:21together.
06:23The machine has a bar that slips into this square-shaped spoon and then thoroughly stirs it.
06:28And you get the spoon so they can minimize the mess during the process.
06:33Quite neat, wouldn't you say?
06:36A regular milk jug has a dent on one side.
06:40Some might see it as a random design decision, but a dent has several purposes.
06:45One of them is to get bigger if there's a gas build-up.
06:49This happens when your milk is spoiled.
06:51So you don't even have to try to check this out.
06:54Also, the dent is there so the jug doesn't burst if you accidentally drop it.
06:59The dent allows the expansion space that deals with the sudden pressure that happens when you drop the jug.
07:07Dental floss.
07:07Sure, it's important for your dental health, and it's easy to assume what you do with it.
07:12But dental floss is great in the kitchen as well, because it's a very precise cake slicer.
07:18Way better than a regular knife.
07:23Most kitchen shears have a serrated opening right there at the center where the blades and handles meet.
07:29It's something you can use to trim difficult herbs such as rosemary, thyme, or chives.
07:35Because of this opening, you don't need to pick the leaves off by hand, but de-stem them in one
07:40motion.
07:42The majority of gelatin containers or single-serving yogurts come with a tinfoil lid.
07:47And in most cases, you can use this covering as a disposable spoon.
07:52Just peel away the covering, and after a couple of simple folds, you'll have a perfect little spoon for your
07:58midday snack.
08:00It's breakfast, and you crack open a hard-boiled egg.
08:03You find that it's green.
08:05Looks disgusting.
08:07Well, it looks like you cooked it for too long.
08:09This happened because of the thin sulfur layer in the whites and iron in the yolk.
08:14Though the mixture of these chemicals is black, it's such a thin layer mixed into the yellow yolk that it
08:19turns green.
08:21But don't fear.
08:22These strange green eggs.
08:23They're completely safe to eat.
08:26While sitting for a photo, it would be weird to say anything other than cheese to get that perfect smile.
08:32But in the 19th century, it was different.
08:35Photographers would ask their subjects to say prune instead.
08:39The reason was to obtain that thin, duck-like expression.
08:42It was considered a prim, improper way to present a photograph.
08:47Strawberries aren't even considered a berry, and are more of a false fruit, further identified as multiple fruit.
08:54What we believe is that the tiny little brown or white things are seeds, but they're actually individual fruits attached
09:01to its flesh.
09:02But how did this mistake start in the first place?
09:05Well, the confusion began hundreds of years ago when it was first named.
09:10However, this was a long time before botanists were even around to help clarify this mistake.
09:16Sci-fi films are often inspired by real-life space exploration.
09:21But there's one thing that NASA implemented after watching a sci-fi movie.
09:25A 1929 flick, Woman in the Moon, introduced a countdown that built up anticipation.
09:30NASA found this helpful and started using it in 1969.
09:35Not only is it an exciting moment, but it does also have a practical use.
09:39It helps the massive team behind each launch ensure they're synchronized perfectly down to the last second.
09:46This one might change your appetite the next time you see a juicy apple.
09:50Usually picked around August to November, the shiny supermarket apples are covered in hot wax, then hot air dried and
09:58sent into cold storage.
10:00Before they arrive at the supermarket looking fresh, they've been in storage for anywhere between 6 to 12 months.
10:07I bet you can't do this.
10:09Try and hum while closing your nose.
10:11No noise came out, right?
10:14Without an exit for air, it's physically impossible to make any noise.
10:19The world's largest national park in Greenland covers a staggering 375,000 square miles.
10:25That's twice the size of California.
10:28But although it's huge, there are only up to 40 permanent residents in this massive area, making it one of
10:35the most isolated places on Earth.
10:38Issues with bad breath?
10:39Gum is the typical choice, but other things are just as effective.
10:43Cucumber is a great natural solution, and a more efficient one.
10:47Working similarly to gum, it helps stimulate saliva production.
10:51But what makes it different from other odor defeaters is its water content.
10:55Washing away any unwanted pieces of food still remaining also helps to avoid a dry mouth, which causes odors.
11:02You would think that Z would be the last letter put into the alphabet, but it was actually J.
11:08Long ago in 1524, an Italian grammarian wanted to identify a way to separate I and J.
11:16Together, they were a vowel.
11:18And J was then used as a consonant that sounded like Y.
11:21It wasn't until 1633, when an English grammar book explained the proper use of J, and it was entered into
11:29the alphabet in the way we use it today.
11:32The first vacuum cleaner was invented in 1901, the size of a Winnebago, and it took four people to operate
11:39it.
11:39A petrol engine used to supply power also required a horse to move it around.
11:44I would suppose that it was mainly used for cleaning up after the horse in the end.
11:48It wasn't long after that they found easier ways to clean the house, and in 1910, the first handheld vacuum
11:55was invented.
11:56If you've been told that you sweat like a pig, there is no need to be offended.
12:00It's actually more of a compliment, as pigs don't sweat.
12:04All swine are born without sweat glands, and the only way to cool off is to find a nice puddle,
12:09or more famously, some mud.
12:12Umbrellas were invented around 4,000 years ago, and were only socially acceptable for women to use them.
12:17Their original purpose was to keep the sun out of your eyes, and as a fashion accessory.
12:22It wasn't until the mid-18th century that men were allowed to use them, and the modern, water-resistant version
12:29we use today was made.
12:31And most importantly, the very first dog umbrella was invented in 1965.
12:38Dentists can be very strict on what sweets you eat, so you would be amazed to learn that cotton candy
12:44was invented by a dentist.
12:46John C. Wharton, a dentist and confectioner, wanted to give his clients a treat every visit.
12:52Hmm, maybe he gave them this treat to ensure they came back more often.
12:59If we could theoretically build a highway to outer space, and could adjust the effects of gravity,
13:04it would only take you an hour to drive to space if you drove at 60 miles per hour.
13:10Let's make this happen, Elon Musk!
13:13How heavy could a cloud be?
13:15It looks like it couldn't weigh too much as it floats easily up in the sky.
13:19But a cloud could weigh anywhere up to 1 million pounds.
13:23That massive cloud is able to float above you because the air is lighter up there, and less dense than
13:28dry air below.
13:29So, you can see the same effect when observing oil floating on water.
13:34You think you yawn because you are bored or tired?
13:37Well, it's a myth.
13:38You yawn more often later in the day, but it's just your body helping you remain alert.
13:43Through inhaling cool air and stretching the muscles, it cools the flow to the brain.
13:48Researchers identified brain sizes in different species of animals based on their yawns.
13:54The larger the brain, the longer the yawn.
13:56So how long do you yawn?
13:59Playing video games regularly increases gray matter in the brain for all you gamers out there.
14:04Which helps to boost brain connectivity through muscle control, memories, perception, and spatial navigation.
14:10An experiment at a New York medical center found that surgeons who played 3 hours of video games
14:15made 37% fewer mistakes and performed 27% faster than other non-gaming doctors.
14:23Have you ever wanted to be just a little bit taller?
14:26Well, get your space boots on.
14:28The human body can grow up to 3% taller when in space.
14:32While living on Earth, our spines are compressed by gravity.
14:35But in zero gravity, the decompression lets the spinal discs expand, allowing the spine to lengthen.
14:42Cows don't have full REM sleep while standing, but they can have a light nap.
14:47This is an evolutionary trait that helps their ancestors avoid predators.
14:51They stand idle during a power nap if they need to make a quick getaway.
14:55They do have full REM sleep, only by lying down.
14:59They only need 4 hours of sleep to fully energize for the next day.
15:03Women have more taste buds than men, and 35% of women are considered super tasters, and only 15%
15:10of men are.
15:12Not surprisingly, more women prefer pineapple on their pizza.
15:15Now, don't be triggered if you disagree.
15:18While sleeping, you're incapable of sneezing.
15:21This might seem impossible, especially when you have a cold.
15:25But while your body is resting, the nerves that help you sneeze are as well.
15:30While you sleep, the brain ignores any irritating sensations or tickling that would typically create the sneeze.
15:37Our calendar year once used to end in February.
15:41This is because it was the last month to be added to the calendar.
15:44A calendar year once only lasted 304 days, so there was plenty of room for more months.
15:51It was changed in the year 46 BCE to the calendar we know today by Julius Caesar.
15:58They previously followed the lunar calendar.
16:00Julius Caesar saw issues with this as it didn't match the seasons.
16:04He hired an astronomer who created a calendar based on the solar year.
16:10Road and construction workers are usually dressed in orange because the bright orange hue is visible even in bad weather.
16:17It's the most effective color to attract attention and alert people.
16:21No wonder lots of safety jackets and traffic cones are orange as well.
16:25The stop sign has an eight-sided shape to help drivers recognize it easily, even if they see it from
16:30the back.
16:31And when the signs weren't reflective yet, the octagon shape prevented drivers from confusing the stop sign with any other
16:38at night.
16:39The rumble strips on the side of the road are placed there to alert drivers who doze off behind the
16:44wheel.
16:44When their tires move over these strips, the noise and vibration work like an alarm clock.
16:50There are magnetic locks on fuel hoses at gas stations.
16:53They come in handy if someone drives away with the gas nozzle still attached to their car.
16:58In this case, the lock detaches the hose automatically.
17:02Oh, that's embarrassing.
17:04Gasoline looks like a rainbow in a puddle because it can't mix with water.
17:07It forms a thin membrane over it.
17:10When light reflects from it, and the water at the same time, you've got a rainbow.
17:15A triple handle on a jerry can is there to make it easier for two people to carry it and
17:20distribute fuel evenly.
17:22Gas cans often have a second hole that actually needs to be uncapped too before you pour the gas.
17:28The air passage will prevent it from pouring out, so no more fuel waste.
17:33Most gas cans have two holes with caps, a bigger and a smaller one.
17:38You're supposed to uncap the smaller hole before pouring gas inside the bigger one.
17:42It'll prevent the liquid from glugging and spilling all over your clothes and the ground.
17:47Another little thingy we often neglect is a point on an ointment cap.
17:51Most tubes are usually sealed with a plastic film or a foil,
17:55and opening it with your fingernails isn't the best idea.
17:58A point easily opens even the most safely sealed tube.
18:02You can use most screwdrivers together with a wrench to create more torque.
18:08Just place the wrench over the handle of the screwdriver.
18:11This way, you'll need to apply a lot less force than before.
18:14You'll also be able to get to hard-to-reach areas more easily.
18:19They install cameras in shops, banks, and hospitals to monitor everything.
18:24If something happens, you can call the police or rescuers.
18:27The camera really helps to solve a lot of problems.
18:30Why are there no cameras on planes?
18:33The crew keep order on the plane,
18:35but they won't be able to do anything if something serious happens.
18:39Besides, there's nowhere to run on the plane.
18:41During the flight, the cameras are useless,
18:44and after the flight, the words of the passengers work ideally instead of cameras.
18:49So, if cameras do no good, then why spend money on them?
18:53Water is great at cleaning stuff because it has triangular molecules.
18:57They're made of one oxygen and two hydrogen atoms.
19:01Um, H2O?
19:02Such molecules have slightly different charges on their opposite sides,
19:06pretty much like magnets.
19:07That's why water easily sticks to other molecules,
19:10including those that make up dirt.
19:12Lots of private houses have triangular-shaped roofs
19:15because this allows rain, snow, and fallen leaves to slide off the slope.
19:20If all this stuff piled up on top of your house,
19:23one day, your roof would collapse.
19:25When a storm is coming, clouds seem to turn dark,
19:29but it's just an illusion.
19:30Thin clouds on a sunny day let the light through easily.
19:33They also scatter all the colors of the light spectrum.
19:37This makes us perceive the clouds as white,
19:39but the thicker the clouds are and the more water droplets they contain,
19:43the less light they let through and the darker they look.
19:47A good doorknob is the one made of brass, bronze, or some copper alloys.
19:52These metals have an anti-germ effect.
19:55Bacteria spread way slower on them.
19:58They also get rid of germs pretty fast, within a couple of hours.
20:02Nope, it doesn't mean you don't have to wash your hands.
20:05Diamonds have such symmetrical shape to show you their brilliance.
20:09Initially, the gems aren't so beautiful.
20:11They go through several stages of cutting,
20:14and then become pieces of elegance.
20:17Most of these stones have a round shape with slightly pointed corners.
20:21Diamonds shine the brightest in this shape.
20:24Why are there two holes in the socket?
20:27The left hole is neutral,
20:28the right hole is not,
20:30and the gap underneath is ground.
20:33Electricity needs to flow through the chain.
20:35The current flows from the hot slot,
20:38passes through your phone charger, for example,
20:40and then goes through the neutral hole.
20:42Ever wondered what that small pocket on your jeans is for?
20:46People used to wear watches on chains.
20:48That small pocket was meant for it.
20:50Now, almost no one wears such a watch,
20:53but the pocket remains.
20:54You can still keep something small in there, like a ring.
20:58In London, there are some poles that look like street lamps,
21:01but there are no bulbs.
21:03Well, their official name is stink pipes,
21:06and they're a thing of the past now,
21:07but they used to come in handy back in the 19th century.
21:10These hollow poles would vent away the air
21:13and explosive gases with bad smells
21:15to prevent, shall we say, unwanted consequences.
21:20Most kitchen shears have metal plier-like teeth in the middle.
21:23Between the handle grips,
21:24they can help you crack nuts,
21:26crab shells, and other tough products.
21:28You can also open jars and bottles
21:31or remove herb stems with their help.
21:34Leather often looks dull to the eye
21:36because it's covered with itsy-bitsy scratches and scrapes.
21:39They scatter the light that hits the material.
21:42When you coat your shoes in a layer of wax,
21:44you fill these tiny crevices.
21:46The surface becomes smoother,
21:48and the rays of light bounce off it more evenly.
21:51That's why the leather looks shiny.
21:54Highlighters are filled with a special
21:56semi-transparent fluorescent ink
21:58that can glow in dim light.
22:00Yellow and light green hues are the most popular
22:03because they don't prevent you from seeing the text
22:06after black-and-white photocopying.
22:08Photocopiers perceive yellow and light green marks
22:11as very pale and don't print them.
22:13They make magnets shaped as a horseshoe
22:16because this increases the magnetic force.
22:18Colors matter, too.
22:20The blue part indicates the south pole.
22:22The red part, the north pole.
22:24The two poles work simultaneously
22:26and increase the attraction force.
22:29The dime-sized holes in elevator doors
22:32is actually a keyhole.
22:34If the doors get stuck,
22:35an operator can open them manually thanks to this hole.
22:38They'll just insert a special key.
22:41The tiny hole in the airplane window
22:43is there to balance air pressure.
22:45The window has three layers.
22:48The outer pane is extremely sturdy.
22:50It can withstand air pressure differences
22:53during take-off and landing.
22:54The inner pane, which is the closest to you,
22:57is made of cheaper materials.
22:58It prevents potential damage to the window.
23:01The hole itself is in the middle pane.
23:04It not only balances the pressure,
23:06but also prevents the window from fogging.
23:09Escalator brushes are there for your safety.
23:12They don't allow you to come too close
23:13to the edge of the escalator.
23:15This way, your clothes won't end up between the steps.
23:18You see the sun as yellow or orange.
23:21Because the atmosphere of our planet
23:23scatters such colors as blue, green, and violet.
23:27This is also why the sun looks warmer
23:29at sunrise and sunset.
23:31Go shopping for some oranges
23:33and I'm sure you'll get them in a red mesh bag.
23:36You'll rarely see them lying around
23:37without one of those.
23:39It's pure marketing,
23:40and that color isn't a random choice.
23:42When packed in a red mesh bag,
23:44oranges appear more orange,
23:46fresher, and more appealing to you.
23:48So, you're more likely to buy them, right?
23:51Lemons are usually sold in green mesh bags
23:54for a similar reason.
23:55If you pack them in red,
23:57they'll appear more orange.
23:58Green goes better with yellow
24:00and makes those lemons stand out.
24:03Mattress manufacturers make a limited number
24:05of different mattresses,
24:07and the only way to make them look different
24:08is to come up with a fancy stitching pattern.
24:11Two mattresses of two different companies
24:13might be the exact same quality,
24:15but cost differently.
24:17Most people will never know it
24:18and will decide that different patterns
24:20mean something in terms of quality.
24:22So, when shopping,
24:24don't mind the pattern at all.
24:26Almost all hotels have white bed sheets.
24:29They choose this color specifically
24:31to show how high their standards of cleanliness are.
24:33The whiter and brighter the sheets are,
24:35the more luxurious the hotel seems.
24:38It's much easier to see dirt
24:39and stains on white linen.
24:41It's like proof that you've checked
24:43into a clean room.
24:44If you ever find yourself stuck
24:46in the trunk of your car,
24:48stay calm.
24:49All cars are supposed to be equipped
24:51with an emergency latch
24:52to help open the trunk from the inside
24:54in the unlikely case it happens.
24:57These latches are so well thought out
24:59that they can be opened
25:00by people of all ages.
25:02More so, handles are designed
25:03to glow in the dark, too.
25:05You can even pull them with a mouth
25:07if there's not enough wiggle room
25:09to use your hands.
25:10Never mind how you ended up
25:11in the trunk in the first place.
25:13Moving on!
25:14If you're ever working
25:15with needle and thread,
25:17remember you don't need
25:18to stick the needle
25:19directly into the spool.
25:20You may end up losing
25:22the needle altogether.
25:23Not to mention,
25:24you can easily hurt your fingers!
25:26A lot of modern sewing kits
25:27these days come with a designated place
25:30for safeguarding the needles.
25:31It's located at the bottom part
25:33of the thread spool.
25:34You'll just need to pull it out.
25:36It's even made to hold
25:37multiple sewing needles at a time.
25:41Disposable ballpoint pens
25:42come with a little secret
25:43of their own.
25:44Did you ever notice
25:45that in some of them,
25:47there's a small hole
25:48in the plastic part?
25:49It's actually a rudimentary
25:51ventilation system.
25:52It's supposed to let the ink
25:54easily make it
25:55to the tip of the pen.
25:57Okay, I know it's in the name,
25:58but you really don't need
26:00to shake the seasoning shaker
26:01to get any product out.
26:03Don't believe me?
26:04Hey, you're not the only one.
26:06Go grab your favorite seasoning bottle
26:08out of your pantry.
26:09If it has one of those
26:11removable plastic caps,
26:12it's perfect for the experiment.
26:15Instead of shaking the bottle,
26:16try holding it from the plastic cap
26:18while it's upside down.
26:20Now gently twist the bottle
26:22from side to side,
26:23and before you know it,
26:25you get some gorgeously
26:26flowing seasoning
26:27without having to wiggle the shaker
26:29and make a mess
26:30all over the stove.
26:32On the same note,
26:33most salt and pepper shakers
26:35should have ridges
26:36on the bottom of the glass portion.
26:38In case you get any seasoning
26:40stuck in there,
26:41place the bottom of the salt shaker
26:42against the bottom
26:43of the pepper shaker
26:44and wiggle it around
26:46so the ridges
26:47click with each other.
26:48The seasoning should easily
26:50pour out now
26:50without you having
26:51to open the bottle.
26:53In colder weather,
26:54you often have so many
26:55clothing layers on you
26:57that you can hardly feel
26:58the purse or back straps
27:00on your shoulder anymore.
27:01Not to mention how fast
27:03they can slide off.
27:04Some jackets come
27:05with a built-in solution
27:06for that,
27:07in the form of a small tab
27:09on the shoulder
27:09with either a hook
27:10or a button.
27:11It's meant to be opened
27:13and closed comfortably,
27:14so you can keep your purse
27:15in place at any time.
27:18You're most likely using it
27:20merely to peel the skin
27:21of potatoes,
27:22carrots,
27:23or cucumbers.
27:24But you can use
27:25your vegetable peeler
27:26for chopping fine strips
27:28of onion as well.
27:29Just cut the onion
27:30into quarters vertically
27:31and then start slicing.
27:33This might also help out
27:35with those embarrassing
27:36onion tears.
27:38Most people miss this one,
27:39but should you ever have
27:41a closer look
27:42at your toothpaste tube,
27:43you will surely see
27:44some sort of coloring there,
27:46either a dot
27:47or a block.
27:48Colors can vary.
27:49They can be black,
27:50green,
27:51red,
27:51or even blue.
27:53These color spots
27:54are actually meant
27:55to help the assembly machines
27:56back at the toothpaste factory.
27:57They recognize
27:59when and where
27:59these machines
28:00need to cut
28:01the toothpaste tubes
28:02and proceed to fold them
28:03for packaging.
28:04For most types of footwear,
28:06if there's anything
28:07that seems a bit out of place,
28:09always know
28:10that it's there
28:10for a reason.
28:11Most manufacturers
28:13don't put extra items
28:14on shoes just for fun.
28:15It would definitely
28:16be a waste of time
28:18and resources.
28:19For footwear,
28:20like boots,
28:21for example,
28:21there's often a small loop
28:23at the top back
28:24of the shoe.
28:24It's there to help you
28:26when you need to put the shoe on
28:27since you can quickly pull on it.
28:29Plus,
28:30you can also hang the shoes somewhere,
28:32most likely to dry,
28:33since most boots
28:34are meant to be worn
28:35in the colder weather.
28:37Now,
28:37I've been guilty
28:38at least once
28:39of overdressing
28:40with a bunch of layers
28:41just so I won't need
28:42to jam everything
28:43in my check-in bag.
28:45But does it become a problem
28:47when you actually
28:48have to get seated?
28:49What do you do
28:49with your coat
28:50or your jacket?
28:51Well,
28:52have a closer look
28:53next time you board a plane
28:54on the seat in front of you.
28:56The hook
28:57that keeps the tray table upright
28:59can double
28:59as a jacket hook.
29:01As long as you don't need
29:02to have any meals
29:03while in the air,
29:04you're good to go.
29:06Now,
29:06most mascaras expire
29:08within 3-6 months,
29:09I'm told,
29:10depending on the manufacturer.
29:12But you can help
29:13speed up that process
29:14if you're not careful enough.
29:16Continuously pumping
29:17the mascara wand,
29:18trying to mix in the product,
29:20actually pushes
29:21more air into the tube.
29:22This can make it dry
29:24much faster
29:24and you evidently
29:26won't get the desired results
29:27with it anymore.
29:29There's an easy way
29:30to check if your mascara
29:31is still good enough
29:32to use.
29:33If you don't hear
29:34a popping noise
29:35when you take the brush out,
29:36you may very well need
29:38to go get yourself
29:39a new mascara tube.
29:41Now,
29:42I know
29:42we're living in the era
29:43of Bluetooth-connected devices,
29:45but for better quality sound,
29:47they still recommend
29:48using headphones
29:49that connect
29:50via audio jacks.
29:51Remember seeing
29:53black ridges
29:53on those jacks?
29:54They aren't there
29:55just to make them fit
29:56when you plug them
29:57into your phone
29:58or laptop.
29:59Made out of a special
30:00insulating material,
30:02these bands are meant
30:03to guard the wires
30:04when sound
30:05is being transmitted.
30:06Based on the number
30:07of bands,
30:08you can figure out
30:08which end goes where.
30:10Some empty space
30:11under noodles
30:12in a cup
30:13doesn't mean
30:13the company producing them
30:15wants to cheat you
30:16out of a full portion.
30:17No, no.
30:18It's a manner
30:19of keeping the noodles
30:20intact during
30:21their transportation.
30:22It also helps
30:23with the circulation
30:24of hot water
30:24that is poured
30:25over the products
30:26before you can enjoy them.
30:28The V-shaped neckline
30:30was initially designed
30:31to serve a bunch
30:32of objectives.
30:33First,
30:33as a way
30:34of prolonging
30:35the life of the garment
30:36that would maintain
30:37its shape
30:37over the years.
30:38It's also there
30:39to fit your head
30:40through the shirt
30:40in case it needs
30:42some stretching.
30:42This way,
30:43it ensures
30:44a snugger grip
30:45around the neck.
30:46Lastly,
30:47it helps absorb sweat
30:48in case you're wearing
30:49the shirt
30:50while exercising.
30:51Now,
30:52it's not necessarily
30:53a custom anymore,
30:54but you may have stumbled
30:55upon a dinner jacket
30:57with an additional
30:58mysterious pocket
30:59on the right side.
31:00Turns out,
31:01this pocket
31:02was used by men
31:03to easily reach
31:04their train tickets
31:05since most of them
31:06had to travel
31:07to work every day.
31:08It helped them
31:09keep their jacket
31:10buttoned up,
31:10but also benefited
31:11from the use
31:12of a pocket.
31:13Now,
31:14it's only added
31:15as a decoration
31:15and it doesn't serve
31:17an actual purpose anymore.
31:19Speaking of things
31:20we don't use these days,
31:21or at least
31:22for their initial purpose,
31:24did you know
31:24Play-Doh was originally
31:26a cleaning product?
31:27In the 1920s,
31:29the market was in need
31:30of a product
31:31that could help them
31:32wipe the wallpapered areas
31:33around coal-burning furnaces.
31:35The recipe
31:36for what we now know
31:37as Play-Doh
31:38was thus invented.
31:40It was manufactured
31:41in white only
31:42and was supposed
31:43to clean wallpaper
31:44by being rolled
31:45back and forth
31:46over the dirt.
31:47It was only later
31:48in the 1940s
31:49that new products
31:50for cleaning wallpaper
31:51were brought up
31:52and Play-Doh
31:54was redirected
31:55toward another
31:56area of the market.
31:57Now,
31:58while I enjoy
31:58a nice piece of toast
32:00for breakfast,
32:01isn't it pesky
32:02to have to clean out
32:03the toaster?
32:04Well,
32:04not anymore
32:05since I recently
32:06found out
32:07that toasters
32:08have a slide
32:09or a panel
32:09at the bottom
32:10that helps get rid
32:11of all those
32:12annoying breadcrumbs
32:13easily.
32:16Now,
32:17there used to be
32:18a time
32:18when you could only
32:19have access
32:19to video games
32:20by inserting cartridges
32:22in your console
32:23of choice.
32:24These tiny objects
32:25gave many doctors
32:26a lot of headaches.
32:28People soon started
32:29popping up
32:30in hospitals
32:30after swallowing
32:32small game cartridges,
32:33especially the younger generation.
32:35Nintendo,
32:36the company
32:37that manufactures
32:38the majority
32:38of these devices,
32:40had to come up
32:40with a creative solution
32:42to prevent
32:42these accidents.
32:43So,
32:44these days,
32:45Nintendo Switch cartridges
32:46are purposely
32:47coated
32:47with specific chemicals
32:49that can leave
32:50a really bad
32:51bitter taste
32:52in the mouth.
32:52Not that I'd,
32:53you know,
32:54recommend you ever
32:54try and taste
32:55for yourself.
32:56Hmm.
32:57Okay,
32:58I know it's kind of
32:59cold to the touch,
33:00especially on a
33:01freezing winter's day,
33:02but did you know
33:02that brass doorknobs
33:03actually serve a purpose
33:04apart from looking
33:05classy and shiny?
33:06Since it's a copper alloy,
33:08brass has antimicrobial
33:10properties.
33:10That means it can help
33:12get rid of harmful germs
33:13and bacteria,
33:14sometimes in up
33:15to two hours.
33:16In high traffic areas,
33:18that's all the more useful,
33:19but since brass is much
33:20costlier than other metals
33:22like nickel and steel,
33:23you barely see these types
33:25of doorknobs anymore nowadays.
33:27Speaking of lovely
33:28multi-purpose items,
33:29most screwdrivers
33:30have a tiny little secret
33:31of their own.
33:32They can sometimes
33:33be slid through a wrench
33:34so that they can be used
33:35to create more torque
33:36when twisting,
33:37not to mention the uses
33:39when it comes to bolts
33:40in hard-to-reach places.
33:42There's a reason
33:43why buttons on women's shirts
33:45are for the left-handed
33:46and it has nothing
33:47to do with fashion.
33:48This practice dates back
33:50to the times
33:50when chambermaids
33:51were helping ladies
33:52dress themselves
33:53and it was easier
33:54for them to perform
33:55their job
33:55with this orientation.
33:57Having the buttons
33:58placed as such
33:59indicated a sign of wealth,
34:01so it's easy to imagine
34:03why the practice
34:03carried on,
34:04even though most people
34:05dress themselves nowadays.
34:07Next time you receive
34:08a package in your mail,
34:10take a look
34:10at your box cutter.
34:12If it features
34:13some diagonal lines
34:14on the blade,
34:14you're in for a little
34:15design perk.
34:16Turns out that
34:17these are blades
34:18that snap off.
34:20Continuously cutting cardboard
34:21can dull the sharp edge
34:22of the blade.
34:23To help prevent the need
34:24to buy a brand new box cutter,
34:26the top segment
34:26along the next line
34:28can be broken off
34:29to reach a new sharp edge.
34:30To do this,
34:32check out the small hole
34:33at the base of the tool,
34:34sometimes called
34:35the blade snapper.
34:37The people that first
34:38came up with this
34:39brilliant invention
34:39were engineers
34:40inspired by the way
34:41chocolate bars
34:42are segmented.
34:43Hold on a minute,
34:44don't throw away
34:45the cardboard package
34:46just yet.
34:47Most likely,
34:47you'll have some
34:48silica gel packets
34:49somewhere at the bottom
34:50of the box.
34:51Since this gel
34:52is basically a drying tool,
34:54it gathers up the moisture
34:55out of its environment
34:56so you can store
34:57these packets
34:57for further occasions.
34:59Whether you'll need
34:59to dry out your phone
35:00or some other
35:01electrical object,
35:02you can place them
35:04in a container
35:04next to the silica gel
35:05to reduce the damage.
35:07You don't have to be
35:09a mechanic to know
35:09when a standard car tire
35:10needs replacing
35:11since they come equipped
35:13with a neat indicator.
35:14Take a closer look
35:15and you'll see
35:16that treads
35:17within the tire
35:18are a bunch
35:18of rubber notches.
35:20When the treads
35:21are evened out
35:21with the perpendicular bars,
35:23it's a sign you need
35:24to book an appointment
35:25with your local car service.
35:27Since most likely,
35:28the tires have lost
35:29most of their traction
35:30and may not be safe
35:31for driving any longer.
35:33The upper corners
35:34of a car windshield
35:35feature textured
35:36black dots
35:37melted into the glass edges.
35:39This neat add-on
35:40isn't there
35:40for design purposes.
35:42It's called
35:43frit glazing,
35:44which means
35:45that a special type
35:46of ceramic paint
35:47is added to the window
35:48for protecting its sealant
35:50from UV rays.
35:51It also conceals
35:53and creates
35:53a coarser surface
35:54for the adhesive used
35:56to set the window in place.
35:58Whenever you're up
35:59for a drive,
36:00check out
36:01if there's a small tab
36:02under your car's
36:03rear view mirror.
36:04Bet you didn't know
36:05it's there
36:06to help switch the mirror
36:07from daytime
36:08to nighttime views.
36:10It uses
36:11a prismatic glass technology
36:13to blur the reflection
36:14and reduce the glare
36:15of headlights behind you
36:16in traffic.
36:18People came up
36:19with these manually
36:19tilted mirrors
36:20in the 1930s,
36:21but they became
36:22standard somewhere
36:23in the 1970s.
36:25While you're in the car,
36:26check out the headrests,
36:28as you most likely
36:29don't know
36:29that they carry
36:30a little disguised purpose.
36:32Of course,
36:33they're adjustable
36:33to accommodate passengers
36:35of any height
36:35so that they get
36:36the proper support
36:37for their heads and necks.
36:38The hidden feature
36:39is that they are detachable
36:41and come with two
36:42very solid metal bars.
36:44Should you ever
36:45find yourself
36:46stuck in a car
36:47and need to make
36:47a fast getaway?
36:49These bars come in handy
36:50to crack out
36:51the car windows.
36:52So you're out
36:53for a drive
36:54and you're suddenly
36:55out of gas.
36:56What I'm about
36:56to describe
36:57sounds more like
36:58a meme
36:58than an actual
36:59situation bound
37:00to happen.
37:00But what if
37:01you're in such a hurry
37:02that you accidentally
37:03drive off
37:04with the gas nozzle
37:05still in the tank?
37:07Well,
37:07the nozzles
37:08have been designed
37:09to prevent any hazards
37:10from happening,
37:11rest assured.
37:12They feature
37:13a breakaway device
37:14that will allow
37:14the hose to separate
37:15when taken out
37:16with enough force.
37:18Initially designed
37:19in the early 20th century
37:21to be worn exclusively
37:22by basketball players,
37:24sneakers soon became
37:25one of those
37:25fashion fundamentals,
37:27similar to jeans
37:27and leather jackets.
37:29If you take
37:30a closer look at them,
37:31you'll see they have
37:31two extra holes
37:32on the side,
37:33similar to the
37:34shoelace holes.
37:35They're manufactured
37:36as such,
37:37not only to provide
37:38extra ventilation,
37:39but to allow people
37:40to get extra creative
37:41with their laces
37:42when wearing the shoes.
37:43Admit it,
37:44you've always thought
37:45that chopsticks
37:45are merged at the end
37:47for the sole purpose
37:48of keeping them together
37:49until you're ready
37:49to dig into your meal.
37:51That may or may not
37:52be the whole truth.
37:54Under a more detailed
37:55inspection,
37:56the wooden tools
37:57feature a square-shaped end.
37:59Chopsticks manufactured
38:00like this
38:00date back to an
38:02old Japanese
38:02traditional design,
38:03which can help
38:04with breaking
38:05the ends easily.
38:06The separated end
38:07can then be used
38:08as a resting block
38:09for the chopsticks
38:10to keep it more sanitized
38:12in hopes it can be used again,
38:13since they won't be
38:15touching the table
38:15or any other surface.
38:18Women's bikes
38:18have a special design,
38:20which, surprisingly,
38:21has a historical
38:22and fashionable purpose.
38:24The lower frame
38:25is for the most part
38:26meant to make up
38:27for the generally
38:27shorter height of ladies,
38:29compared to that
38:29of the average gentleman.
38:31While that is the case
38:32for handlebars
38:33and saddles,
38:34the overall frame
38:35is lower
38:36for an additional purpose.
38:37Way back when women
38:38wore long skirts
38:39and dresses all day,
38:41every day they needed
38:42to make sure their outfits
38:43wouldn't get caught
38:44in the frame.
38:45That's how we came up
38:46with a lower-framed bicycle,
38:48perfectly made for women
38:49and their needs
38:50at the time.
38:52The fact that
38:53toothpastes
38:53are multicolored
38:54is not just a nice perk
38:56to make dental hygiene
38:57more fun.
38:58There's a secret meaning
38:59related to each of the colors,
39:00which dates back
39:01to the 1970s.
39:03In those days,
39:04people grew more
39:05and more interested
39:06in their oral health care
39:08and as such,
39:09they were looking
39:10for products
39:10which could do more
39:11than merely clean
39:12their teeth.
39:13One company
39:14was the pioneer
39:15in that regard,
39:16adding mouthwash
39:17to its toothpaste,
39:18meaning the blue strip.
39:19They later added on
39:21the red strip,
39:22meant to feature ingredients
39:23which helped
39:24with gum care.
39:25Speaking of toothpaste,
39:27check the cap
39:27next time you open
39:28a new tube.
39:29You may be in
39:30for a little surprise.
39:31There's a pointed cone shape
39:33inside the cap
39:34so you can puncture
39:35the seal of the toothpaste
39:36without cutting yourself
39:37or ruining your manicure.
39:39Not to mention,
39:40it's more hygienic
39:41since you won't be able
39:42to transfer germs
39:43or other bacteria
39:44into the product itself.
39:46On the subject
39:47of bathroom countertop items,
39:49toothbrushes come
39:50with a neat add-on
39:51hidden in the bristle patterns.
39:53Apart from making
39:54the toothbrush look cooler,
39:55they also do come
39:56with a practical purpose.
39:59Most toothbrushes
40:00come with a pattern
40:00of blue bristles
40:01intertwined with white ones.
40:03The blue dye
40:04is meant to fade out,
40:05signaling the time
40:06when you need
40:06to replace your toothbrush.
40:09Dentists say
40:10that toothbrushes
40:11should be replaced
40:11every three to four months,
40:13but it does serve
40:14as a great reminder
40:15in case you forget.
40:16Still love playing
40:17with Lego?
40:18Don't judge.
40:19Hey, it's a great hobby
40:20for all ages.
40:21Notice there's a hole
40:22on top of the Lego heads?
40:24Behold,
40:25you're looking at
40:25a safety feature
40:26that the people at Lego
40:27designed to prevent
40:29choking hazards.
40:30The most dangerous issue
40:32should a person
40:33swallow any of these pieces
40:34is the blocking
40:35of the airways.
40:36Designing a hole
40:38inside the Lego head
40:39helps the air
40:40to flow freely
40:40through the piece
40:41until it can be
40:42removed safely.
40:44We're now used
40:45to all sorts
40:45of modern light bulbs,
40:47some tubular,
40:48some shaped like diamonds,
40:49and some even
40:50twisted all together.
40:52Historically,
40:53light bulbs were round
40:54and the initial shape
40:55served a purpose
40:56in itself.
40:57It was mainly connected
40:58to the fact
40:59that glass bulbs
41:00were hand-blown,
41:01which gave them
41:02the round shape
41:02to begin with.
41:03The hidden practical reason
41:05was that the light bulb filament
41:06needed to be
41:07at the same distance
41:08from every surface
41:09of the glass sphere.
41:10The easiest way
41:11to achieve this
41:12was to make the glass
41:13in the shape
41:14of a globe.
41:16Seatbelt on the passenger seats
41:18has a fabric loop.
41:20When put under
41:20a great amount of pressure,
41:22the stitches on the loop
41:23rip apart so the excess fabric
41:25can assist in cushioning
41:26the passengers.
41:28The extra few inches
41:29can make a great difference
41:30within a dire circumstance.
41:32However,
41:33there isn't one
41:34on the driver's side.
41:35As the driver is so close
41:37to the steering wheel,
41:38it's safer for them
41:39not to have one.
41:41Seatbelts were originally invented
41:43in the mid-19th century,
41:44though this technology
41:45wasn't brought
41:46into common practice
41:47until the 1960s.
41:49Pre-collision sensory technology
41:52has assisted with developing
41:53the safety of seatbelts
41:54and other features
41:55to the next level.
41:57Effectively predicting
41:58a car's collision,
41:59the technology directs
42:00the seatbelts
42:01to automatically tighten,
42:03aligning the airbags
42:04and ensuring the brakes
42:06will be preloaded
42:07to reduce shock.
42:08Every year,
42:10six million car accidents occur,
42:12which explains why
42:13all cars still must continue
42:15to develop safety features,
42:16not only to alleviate accidents,
42:18but to protect people
42:19more effectively
42:20within their cars.
42:22The materials that make up
42:24the body of cars
42:25only started getting replaced
42:27within the last 25 years,
42:29ranging from aluminum
42:30and magnesium alloys
42:31to carbon fiber composites.
42:33These lighter materials
42:35not only enable
42:36a more fuel-efficient journey,
42:37but they also ensure
42:38that when a car
42:39is in an accident,
42:40its build provides
42:42a crumple zone.
42:43As a car hits another object,
42:45the crumple zone
42:46absorbs energy
42:47from the collision.
42:48Although this would appear
42:49to cause more damage
42:50to the car,
42:51it helps prevent impact
42:53on the passengers.
42:54Front and rear bumpers
42:56are very underrated,
42:57and due to their long history
42:59of being used in cars,
43:00you can't imagine
43:01a time we didn't use them.
43:03They were invented
43:04in the late 1800s.
43:06The bumpers evolved
43:07over the years
43:08to the point
43:08we don't even realize
43:09we have them.
43:10But they're there,
43:11quietly waiting
43:12under the outer covers,
43:14consisting of compressible foam
43:16or plastic
43:16around a rigid reinforced bar.
43:19All the windows
43:20of your car
43:21are made of glass,
43:22but the windshield
43:23is made of a shatterproof version.
43:25It's laminated,
43:27so whatever might hit it,
43:28you can be sure
43:29there won't be
43:30any shards of glass
43:31falling into the front seats.
43:33Normal glass was used
43:34up until the 1950s.
43:36As vehicles became
43:38more prominent,
43:39they made modifications
43:40to ensure safety.
43:42Airbags seem like
43:43another common feature
43:44that has always been there.
43:46In fact,
43:47they were originally invented
43:48in 1968
43:49and were ahead of their time.
43:51They slowly gained popularity,
43:54and through safety precautions
43:55for cars,
43:56they eventually became mandatory
43:57for all cars to have
43:59only in 1998.
44:01They have since developed
44:02from just being an airbag
44:04within the steering wheel.
44:05Today,
44:06depending on the vehicle,
44:07they can be located
44:08throughout the car,
44:10ensuring all potential passengers
44:11will be protected.
44:13Crash sensors connected,
44:14to an onboard computer,
44:16detect when a collision occurs,
44:17and trigger the bags,
44:19inflating within milliseconds,
44:21and providing a cushioned safety
44:23within a blink of an eye.
44:25It can be difficult
44:26to predict the weather,
44:27and even more so
44:28to determine traction
44:29on the road.
44:30In the late 1960s,
44:32anti-lock braking systems,
44:34ABS,
44:35were implemented in vehicles.
44:37Before that,
44:38they had been used
44:39in many aircraft,
44:40with designs going
44:41as far back as 1908.
44:43They soon became
44:44a necessity for all vehicles,
44:46ensuring traction
44:47is maintained
44:48on slippery surfaces,
44:49and that there is
44:50complete control
44:51when braking.
44:52Today,
44:53ABS has advanced so much
44:55that the latest variations
44:57ensure further detection
44:58when there are strong crosswinds.
45:01Cruise control,
45:02initially invented in 1948,
45:04has been in constant development
45:06over many decades.
45:07Today,
45:08adaptive cruise control
45:10ensures that when the car
45:11is cruising at a constant speed
45:13and detects a slower car ahead,
45:15it will then adjust the speed
45:17to match the car in front.
45:18Other advanced variants
45:20may also ensure
45:21the car will make
45:21a complete stop
45:22once identifying
45:23that the car in front
45:25has done the same.
45:26It's easy to forget
45:28to have your high beams on
45:29when driving on the long
45:30and lonesome road
45:31for many hours.
45:32Automatic high beams
45:33are quickly becoming
45:35more common.
45:36High-tech camera modules
45:38can easily determine
45:39what type of light
45:40is passing through
45:41and help ensure
45:42when the high beam
45:43will be necessary.
45:44Although versions
45:45of automatic high beams
45:47have been around
45:47since the 1950s,
45:49they counted on
45:50light-sensitive sensors
45:51and were very unreliable.
45:53The new varieties
45:54can identify the sources
45:56of light,
45:56whether it's from the sun,
45:58directly from a car's light,
45:59or even from the reflection
46:01on a sign,
46:02ensuring you won't cause
46:03issues with other drivers.
46:06It's a pain in the neck
46:07to have to ensure
46:08there isn't anyone
46:09creeping into that
46:10semi-visible corner,
46:11the blind spot,
46:13which causes around
46:14400,000 accidents per year.
46:16Solar sensors
46:17within rear bumpers
46:18of vehicles
46:19and blind spot
46:20monitoring systems
46:21watch and identify
46:22adjacent lanes.
46:24They alert the driver
46:25that a vehicle
46:26may be in the lane
46:27beside them,
46:28whether by flashing lights
46:29on the dash
46:29or from beeping sounds.
46:31This way,
46:32they help to alleviate
46:33the many concerns
46:34the blind spot causes.
46:361.6 million road accidents
46:39are caused by texting
46:40and driving,
46:41and fatigue normally causes
46:43up to 10%
46:44of all car accidents
46:45per year.
46:46The driver attention monitor
46:48helps to alleviate
46:49both statistics.
46:50It works through sensors
46:52that monitor the car's movements
46:54and the amount
46:54of steering corrections
46:55to ensure the driver
46:57is paying attention
46:58to the road.
46:59When the system identifies
47:00that the driver
47:01isn't completely awake
47:02or is slightly distracted
47:04with their phone,
47:04it will prompt signals
47:06to suggest
47:06it's time for a break.
47:08Tires are among
47:10the most critical components
47:11for your car
47:11with a close relationship
47:13with whatever path
47:14you take.
47:15Many safety features
47:16rely on the tires themselves
47:18for their own
47:18independent purposes.
47:19That's why it's super important
47:22to ensure the tires
47:23are always in top condition.
47:24Tire pressure monitoring systems
47:26check the air pressure
47:27of all four tires,
47:29ensuring you're aware
47:30when they need
47:31their pressure increased
47:32to avoid the risk
47:32of a blowout.
47:34The constant evolution
47:36in technologies
47:36continues to ensure
47:38you stay safe
47:39on longer stretches
47:40of the road.
47:41Lane departure warnings
47:42focus on the lines
47:43on the road,
47:44ensuring the car
47:45stays within.
47:46Whenever a car
47:47starts drifting
47:48over a line in the road
47:49without signaling
47:50to do so,
47:51the camera-based feature
47:52identifies and signals
47:53to the driver.
47:55The lane-keeping assist feature
47:57follows the same method
47:58of identifying
47:59when the car
47:59is intruding
48:00the bordering lane.
48:01When it gets too close,
48:03it will readjust
48:04the steering
48:04and center the car
48:06within its appropriate lane.
48:08Other features
48:09in more advanced cars
48:10have autonomous
48:11driving capabilities.
48:13The autopilot systems
48:14have taken cruise control
48:16to the next level.
48:16Not only does it
48:18allow the vehicle
48:18to steer itself
48:19in the intended lane
48:20while maintaining
48:21a set speed,
48:22but it also changes
48:24lanes when required,
48:25making the ride
48:26more and more efficient.
48:28Some safety features
48:29are only just making
48:30a trend in car models
48:31worldwide.
48:32For example,
48:33night vision
48:34using thermographic cameras
48:36to look out
48:36for pedestrians
48:37and animals nearby.
48:39It goes within
48:40the infotainment screen,
48:41facing frontwards
48:42and identifying objects
48:44from their heat signatures.
48:46It's estimated
48:47that there are
48:47over 1.4 billion cars
48:49in use worldwide.
48:50And as the world's
48:52population increases,
48:53it's expected
48:54that the number of cars
48:55will follow suit.
48:57Safety features
48:57will continue to adapt
48:59further beyond
48:59what we know of today.
49:02Infrared headlights
49:03will be further adapted
49:04to be used in conditions
49:05with poor visibility,
49:06like storms,
49:08snow,
49:08and fog.
49:09They'll be capable
49:10of enhancing
49:11the visibility
49:11of the driver
49:12in all conditions
49:13without affecting
49:14the sight
49:14of passing drivers.
49:16Driver override systems
49:18will soon be able
49:19to monitor
49:19and identify
49:20human behavior.
49:21Whether due to
49:22reckless conduct
49:23on the road
49:23or for other
49:24safety precautions,
49:26cars will soon
49:27have the functionality
49:27to take complete
49:29control of themselves,
49:30ensuring both
49:31the passengers
49:32and the driver's safety.
49:34Augmented reality
49:35windshields
49:35are in early
49:36development already,
49:37providing some
49:38indicator reflections
49:39from the dash
49:40onto the windshield.
49:41So, it's quite possible
49:43that soon all
49:44necessary directions
49:45from maps
49:45and alerts
49:46will appear
49:47right in front
49:47of the driver
49:48to ensure
49:49they never take
49:49their eyes
49:50off the road.
49:52Airbags will soon
49:53not only just be used
49:54within a car
49:55to ensure
49:55the passenger's safety,
49:57they will also activate
49:58from the outside
49:59of the car
49:59once they identify
50:00a definitive collision.
50:02The airbags
50:03will inflate outwards,
50:04covering the entire
50:05outside of the car
50:06and drastically
50:08reducing its impact.
50:09It may be so advanced
50:10that the bodywork
50:11of the car
50:12won't even need
50:13to be buffed out.
50:14The future technology
50:16of cars
50:16is expected
50:17to be so progressive
50:18that the cars
50:19themselves
50:19will have their
50:20own form of communication,
50:22not with human drivers,
50:23but with other cars.
50:25Just imagine,
50:26cars communicating
50:27and sharing information
50:28as they identify
50:29roadblocks,
50:30issues on the road,
50:32or disruptive
50:32weather patterns.
50:33It will all ensure
50:34the most efficient
50:35and safest route possible.
50:41The cylinder
50:42on the end
50:43of a cable
50:43is sitting there,
50:45useless as it might seem.
50:47In fact,
50:47this is a ferrite bead
50:50that assists
50:51with many electrical wires
50:52to reduce
50:53electromagnetic interference.
50:55Electrical wires
50:56act like unintentional antennas,
50:58broadcasting the EMI.
51:02There's a reason
51:03why the spinning wheel
51:04inside their microwave
51:05is circular.
51:06A circular object
51:07will evenly distribute
51:09the heat
51:09as opposed to
51:10a rectangular
51:11and square one.
51:12When you place
51:13containers of these
51:14shapes inside,
51:15the energy is focused
51:17on the corners,
51:18rather than spread evenly
51:19like in a round container.
51:22The temperature gauge
51:24on a toaster
51:25is commonly used
51:26to determine
51:26how crisp
51:27you like your toast.
51:28But the other,
51:29more specific use
51:30for the gauge
51:31was for the different
51:32types of bread.
51:33White and sweet
51:35types of bread
51:35heat up much faster
51:37as opposed to
51:38heavier brown
51:39and rye ones.
51:40The older bread is,
51:42the more time
51:42it will need
51:43in a toaster
51:44to ensure
51:44the golden brown results
51:46you're looking for.
51:48Most ovens
51:49give you the option
51:50of leaving the door
51:51ajar
51:52when broiling
51:53a dish inside.
51:54You probably think
51:55the goal here
51:56is to help
51:57cool down the oven
51:57after use.
51:58In reality,
52:00its purpose
52:01is to focus
52:01on cooking
52:02the top of the dish
52:03and to ensure
52:04a crusty layer.
52:06Controlling
52:06the buildup
52:07of heat and steam
52:08by releasing it
52:09through the slightly
52:10ajar door
52:11gives you the desired result
52:13without cooking
52:14the entire dish
52:14to a crispy end.
52:17You probably've noticed
52:18that your dishwasher
52:19has specific areas
52:21for different types
52:22of cutleries
52:22and dishware.
52:24But all the dishware
52:25pieces should be
52:26facing towards the center
52:27and not all
52:28in one direction.
52:30What types of foods
52:31were on the plates
52:32will also determine
52:33where they should
52:34be located
52:35in the racks.
52:36As the middle
52:37of the machine
52:38gets the strongest spray,
52:39carb-based stains
52:41from tomatoes
52:42and potatoes
52:42should be placed there.
52:44The detergent
52:45is more focused
52:46on the outside
52:46during the clean,
52:48creating a waterfall-like
52:50cleanse.
52:51That's why
52:51protein-based stains
52:53like from eggs
52:54for example,
52:55should be stacked there.
52:58Ceiling fans
52:59push cool air down
53:00on a hot day,
53:02circulating the room.
53:03But they can serve you
53:04during the winter
53:05just as effectively
53:06if you flick that switch
53:07on the side
53:08or use the pulley.
53:10So if you want
53:11to save some money
53:12on heating
53:12and try to quickly
53:13warm up your room
53:14on a cold day,
53:15turn the fan on.
53:16It will push the air up
53:17and spread the warm air around,
53:19more effectively
53:20warming the room up.
53:23Do you still use
53:25sticky notes
53:25instead of those
53:26fancy new apps
53:27on all possible gadgets?
53:29Welcome to the club!
53:30Regardless of what
53:31you use them for,
53:32they can annoyingly
53:33curl up.
53:34If you've had this issue,
53:36it's because you've peeled them
53:37from the bottom upwards.
53:39Doing it this way
53:40causes the curling.
53:41Peeling them from the side
53:43will ensure
53:43they remain flat,
53:44ready to remind you
53:45of your daily tasks.
53:48Did you know
53:49that can openers
53:50weren't invented
53:51until 50 years
53:52after preservation cans
53:53had been readily available?
53:55So how would it be possible
53:56to open a can?
53:58There are a couple
53:59of alternative methods
54:00just in case
54:01you've misplaced
54:02your trusty opener.
54:04All you need
54:04is a metal spoon.
54:06Set the can down
54:07on the counter,
54:08hold onto it firmly
54:09and grasp the head
54:11of the spoon tightly.
54:13Apply pressure
54:14and vigorously rub
54:15the edge of the can's top
54:16over a small area.
54:18It takes time,
54:19but as you continuously rub,
54:21a small indentation
54:22soon opens a hole.
54:23Once the hole
54:24is wide enough
54:25for the spoon's tip,
54:26pry the lid upwards
54:27and keep going
54:28along the edges
54:29until you can finally
54:31access the hard-earned
54:32meal within.
54:34Most toilets rely
54:36on water pressure
54:37and gravity to function,
54:38so a power outage
54:39will not affect them.
54:41But if yours does
54:42need electricity
54:43to function,
54:44you must be worried
54:45about using it
54:45when the power is out.
54:47The good news is
54:48the power is only used
54:50to fill the toilet
54:50and not to flush it,
54:52as the flushing mechanism
54:53will still work.
54:54Open the toilet tank
54:55and pour in a couple
54:56of gallons
54:57and you're free
54:58to flush away
54:58whatever you need to.
55:01Blockages in shower drains
55:03occur over a long
55:04period of time.
55:05It's inevitable.
55:06We lose 50 to 100 hairs
55:08a day
55:09and many of them
55:10will endeavor
55:10to reside within
55:11our shower drains.
55:13Hair only forms
55:14the foundations
55:15of the blockage
55:16and this attracts
55:17the build-up
55:17of various other things.
55:18A great life hack
55:20is to use
55:21your vacuum cleaner
55:21and put the nozzle
55:22in the hole
55:23once removing the plug.
55:25Apply a wet cloth
55:26around the nozzle
55:27ensuring air
55:28cannot escape.
55:29The vacuum
55:30will suck up
55:31the blockages
55:31a lot easier.
55:32This will help
55:33avoid any extra costs
55:35from plumbers
55:35as they themselves
55:37use this technique.
55:40To make your candles
55:41last longer,
55:42trim their wicks
55:43multiple times
55:43and keep them
55:44as far away from water
55:45and moist as possible.
55:47It will guarantee
55:48that your candle's wax
55:49stays firm
55:50and steady
55:51and continues
55:52to burn slower
55:53for a longer period
55:54of time.
55:56The empty space
55:57between the panes
55:58of the oven door
55:59is there for a reason.
56:01You can stick a brush
56:02in there to clean
56:03the oven door glass.
56:04It's easy to access
56:06the space through
56:06the bottom of the door,
56:08open the lower shelf,
56:09then push the brush
56:10through the hole.
56:12While you're parking
56:13in a garage,
56:14you might find it
56:15difficult to determine
56:16how close to it
56:17you need to be.
56:18Not all cars
56:19have sensors
56:20ensuring you keep
56:21the right distance
56:22before the bumper
56:23makes an indentation
56:24on the wall.
56:25Applying a rope
56:26with a tennis ball
56:27from the ceiling
56:28at the right distance
56:29will help you learn
56:30the best distance
56:30to park from the wall.
56:33We've all been told
56:34to loosen a lock
56:35with WD-40
56:36or lubricant.
56:37Yes, we all know
56:38we should have these
56:39around the house.
56:40But in case you don't,
56:42a great alternative
56:43is drawing with
56:44a gray lead pencil
56:45along the edges
56:46of the key
56:46and then putting it
56:47into the lock.
56:49Continue doing this
56:50until the keyhole
56:51has been adequately
56:52lubricated
56:53and the key functions
56:54smoothly.
56:56Pliers are prone
56:57to damage
56:58when you use them
56:59to adjust faucets
57:00and shower heads
57:00and are also
57:01difficult to grip.
57:03Take a couple of pieces
57:04from the end
57:05of an old garden hose
57:06and attach them
57:07to the jaws
57:08of the pliers.
57:09You'll find a huge
57:10improvement with grip
57:11and will avoid
57:12wear and tear.
57:15You can find
57:16a good use
57:16for discarded rubber
57:17for different things
57:18around the house.
57:20When fed up
57:20with tightening
57:21or loosening
57:22with a screwdriver,
57:23try using
57:24a simple rubber band.
57:25Place part of it
57:27into the screw grip
57:28and the screwdriver
57:29will have far
57:29greater traction.
57:32Moving cement blocks
57:34isn't safe
57:34for your lower back.
57:35Even with a wheelbarrow,
57:37it can be a risky process
57:38to place the cement
57:39onto the ground
57:40without causing damage.
57:42Three simple cylinder pipes
57:43can make a world
57:44of difference,
57:45regardless of the size
57:46of the block.
57:47Try lifting the edge
57:48onto the first pipe
57:49with a pry bar,
57:51then pushing
57:52and maneuvering
57:53as you gradually direct
57:54the three pipes
57:55towards the desired location.
57:57Just make sure
57:58you're not doing this
57:59on a slope.
58:01That first strike
58:02on a nail
58:03can be a great success
58:04or will result
58:05in a throbbing thumb.
58:07A bobby pin
58:08is perfectly shaped
58:09to hold a nail in place,
58:11allowing for your hand
58:12to be clear
58:13out of harm's way
58:14and for you
58:14to strike the nail
58:15without fear.
58:17Use a crayon
58:19instead of a pen
58:20or pencil
58:21while working
58:21with a wet saw
58:22to ensure the markings
58:23are not removed.
58:25They will also be easier
58:26to see under
58:27the murky water.
58:30Checking the drains
58:31on the roof
58:32and determining
58:32when they need
58:33to be cleaned
58:34can take a lot of time.
58:36Using duct tape,
58:37attach a mirror
58:38on the end
58:39of a long broom
58:40and review
58:41whether the drains
58:42need to be cleaned.
58:43To further assist
58:45with your balance
58:45as you check
58:46on the gutters,
58:47attach a pair
58:48of old trainers
58:49to the end
58:49of the ladder.
58:50The spread
58:51of the shoe
58:51and its grip
58:52will ensure
58:53a further level
58:54of safety.
58:56Liquid caulk
58:57normally comes
58:57in huge tubes
58:58so you can never
58:59use it all at once.
59:01The hardened tips
59:02of liquid caulk
59:03create blockages.
59:04Grab a used cork
59:06and drill through it
59:07to make a perfect lid
59:08concealing the liquid caulk.
59:10Now it's ready
59:11to be used again
59:12with no blockages.
