00:00Have a good look at the front of your sweatshirt.
00:02Okay, let's ignore the pizza stains for now.
00:05Ever notice that V-shape right at the bottom of the collar?
00:08That small V-patch isn't just a decoration, it serves more than one purpose.
00:12Made from a double layer of webbing material, just like waistbands and cuffs,
00:16these inserts allowed the wearer to put on the sweater without losing any shape over time.
00:21As the sweatshirt would be pulled down over the head,
00:24the V-insert would stretch and flex to allow a lot of wiggle room.
00:28The other benefit the V-pattern gives is to absorb all that sweat.
00:32The chest is a major area of perspiring.
00:35Just look at soaked shirts after doing something physical.
00:38Although the V-insert can only take so much.
00:42That extra pocket on the right side of a suit jacket is called the ticket pocket.
00:46They used to store coins for people on horseback to pay tollbooths without opening their jackets.
00:51When train travel became more popular, they were perfect for tickets and passes.
00:55As for the left chest pocket, it's used to store handkerchiefs,
00:59keeping them away from the other cluttered and dirty pockets.
01:03Metallic zippers have a hidden lock built in.
01:05Next time you've put on a pair of pants, shorts, or skirt,
01:08never leave the zipper handle in an upward position.
01:11Push the little zipper tab downwards, and it'll automatically lock.
01:15To mute your annoying beeping microwave, look closely at the front panel for a sound button.
01:21It may have been there all along, just begging to be pressed.
01:24If there's no button, try pressing and holding 1, 0, stop, or cancel.
01:29It will either result in turning off the beeping sounds or activating a lock feature.
01:34Of course, if your microwave doesn't have any mute function at all,
01:37you'll just have to keep running to stop the timer late at night.
01:41Nintendo Switch cartridges have a hidden safety function,
01:44and it's going to leave a bad taste in your mouth.
01:46Although non-toxic, denotonium benzoate coats the cartridge in a sour, peppery, and bitter substance
01:52to prevent kiddos from swallowing them.
01:55This chemical compound is one of the most bitter flavors known to humanity,
01:59commonly used to keep people from consuming things they're not meant to.
02:03There's not much privacy while using a public toilet,
02:06especially when the door doesn't reach the floor at all.
02:08But these gaps are there for emergency access,
02:11in case the person inside needs immediate help.
02:14The gap also works for ventilation, thank goodness,
02:17and to stop people from lingering around the toilet too long.
02:21Toothpicks have a built-in holder to prevent you from just leaving them on the table.
02:25Just break off the top, it's that simple.
02:27Place that on your table and your toothpick between the notches.
02:31Pointy end up, of course.
02:32Now, it won't touch the table and get all dirty.
02:35You can do the same with disposable chopsticks.
02:38Break off the top piece before you pull them apart.
02:41Those tiny dimples on golf balls actually give a greater lift to the ball and reduce air resistance,
02:46meaning the ball can go further with them.
02:49These dimples come in spherical and hexagonal shapes,
02:52with each slightest change affecting the ball's performance.
02:55So, choose them carefully.
02:57Plastic wrap boxes have hidden little holders that stop the roll from jumping out of the box.
03:02They're little cardboard tabs on the sides that lock into the tube inside
03:06while making it easy to glide the film out.
03:09Just push them in and never be frustrated again.
03:13Gosh, I wish that would work with other stuff.
03:15The seven spikes on top of the Statue of Liberty's crown
03:18don't represent the seven seas and the seven continents at all.
03:22They're representing the sun's rays, giving a halo to show that she is divine.
03:27In the United States, 12 different Federal Reserve Banks print all the money.
03:32So, if you want to know where your money comes from, just look for these small codes.
03:58Meanwhile, the bristles on the side of every escalator are in place to encourage people
04:05to stay away from the edge, meaning they're less likely to face a mishap with a trapped bag or shoelace.
04:12Did you hear about the octopus caught on the escalator?
04:14It was a stretch.
04:16Old-fashioned pin cushions that are large tomato with a strawberry attached
04:19are more than a place for your needles.
04:22The strawberry contains an emery board.
04:24When you stick your pins and needles into the strawberry,
04:27the emery board keeps them rust-free and sharpens them as well.
04:30Some people still forget to engage the hose from their car after filling up with gas.
04:36Luckily, a lot of gas companies realize this.
04:38So, if you happen to drive off with a hose still attached to your car,
04:42there's a magnetic connector that disengages when pulled.
04:45Those different colored bread tags use a color-coded system to show the day that they were baked.
04:51They are usually blue tags for Mondays, green tags for Tuesdays,
04:55red tags Thursdays, white tags Fridays, and yellow tags for Saturdays.
04:59On the back of most beauty products,
05:02you'll find a small symbol on the back that indicates how long it'll stay good for.
05:06For example, 2M means two months after opening.
05:10Some jackets have those extra flaps with a button on the shoulder,
05:14and they actually have a use.
05:16These are perfectly designed for holding your purse, backpack, or bag in place and secure.
05:21Pom-poms on the top of beanies were never just a fashion statement.
05:25They were for protection, placed on top of the headwear to protect sailors from
05:29accidentally hitting their heads while moving around on a ship.
05:33Pom-poms touch the roof, so don't go any higher.
05:36They don't appear on every type of measuring tape,
05:39but diamonds or black circles are there to help contractors measure the proper placement of studs in a wall.
05:46Those little holes on your baseball cap aren't some fashion trends that stuck around for years
05:51and have never been changed.
05:52These holes are actually called eyelets,
05:55and they're to keep your head well ventilated, not for appearance.
05:58If you have YKK printed on your zipper,
06:02they're not some secret code to be cracked.
06:04Those three letters appear on so many zippers globally
06:06because they're the symbol of the world's most universal zipper manufacturer,
06:11the YKK Group.
06:13Every can of soda comes with a tab for easy opening of the tasty beverage,
06:17and every single one of them has a relatively large hole in the top.
06:21While it can make it easier to get your finger under the tab to get your soda,
06:25its intended purpose is a straw holder.
06:28Spin the tab over the opening and place your straw through it to secure it in.
06:33Disposable lids do a great job of keeping your drink inside the cup,
06:36but that's not its only purpose.
06:38When you're ready to sip on your drink,
06:40the lid has specially designed ridges to double it as a coaster
06:43and hold on to the bottom of your beverage tightly.
06:46The tiny black dot between the lens and the flash on the back of your iPhone
06:51is actually for a great purpose.
06:53It's the third microphone to provide superior sound quality
06:56by eliminating background noises
06:58and to pick up your voice much clearer in a crowded environment.
07:02Gas cans that have two holes with caps
07:05aren't there to fill different-sized equipment.
07:07The second hole is meant to be uncapped
07:10before you pour your gas to prevent that glugging effect.
07:13By allowing more airflow through,
07:15the smoother the gas will pour out.
07:17That little arrow next to the gas symbol on your car's dashboard
07:21shows you which side your gas tank is on.
07:24It'll help you when you go fill up your gas tank,
07:26especially if you're borrowing a different car than your own.
07:29Look at a check and see MP near the signature line.
07:34That means the check printer used microprint as one of the check security features.
07:38The lines look like a regular line to the untrained eye,
07:42but they're words like the bank's name,
07:44authorized signature, United States government,
07:46or even original document.
07:49That little disc that's underneath bottles
07:51isn't just a leftover part of the production process.
07:54It creates an even tighter seal with the lid.
07:57So, even if the bottle was turned upside down,
08:00the liquid doesn't leak out everywhere.
08:02The plastic disc keeps carbonated sodas carbonated for longer with this seal.
08:07The indent in the bottom of wine bottles is called a punt.
08:11But it's not just something to help you hold onto the bottle.
08:14The punt makes the wine bottle stronger,
08:16so if dropped, the cork won't fly across the room with all that pressure.
08:21I have a collection of questions you've always wanted the answers to.
08:25Let's go!
08:27First, an observation.
08:29Cookies and baguettes are basically kinds of bread.
08:33So, my question is,
08:34why when left outside for the night,
08:37a cookie gets soft and a baguette becomes hard?
08:41It doesn't make any sense.
08:43Well, the thing is, cookies are sugary bread.
08:46The sugar and salt in them soak up the moisture from the atmosphere,
08:51so they get soft.
08:54Baguettes don't have much salt and sugar,
08:56so they don't attract water and just dry out.
09:01Superglue sticks everything to everything,
09:04but how come it doesn't get stuck to the tube?
09:07Turns out that the glue needs some compound with hydrogen to polymerize.
09:13In the tube, there's just oxygen and no water,
09:16but outside, there's plenty of moisture.
09:19Also, this explains why the stuff always sticks so well to your fingers.
09:24They're warm and perfectly moist.
09:28I'm sure you cried at least once when cutting an onion.
09:32Why does it happen?
09:34So, onions and garlic contain amino acids,
09:37and one of the compounds gets decomposed when being sliced.
09:41It turns into an irritator when it comes in contact with water,
09:45in particular, your eyes.
09:47Your eyes release tears to wash the irritant away,
09:51so that's why you cry.
09:53There are a couple of tricks that can prevent it.
09:56When cutting an onion,
09:57try keeping a sugar cube between your teeth.
09:59It'll absorb the irritant.
10:01Another life hack is to hold a small piece of bread between your lips.
10:05It can help you too.
10:08Why do you see things when rubbing your eyes?
10:11These colors and shapes are called phosphenes.
10:14The reason why you see them is that when rubbing,
10:16you increase the pressure in your eyeballs
10:19and activate the neurons of the retina that process visual information.
10:23Once they're activated,
10:25your brain interprets it as seeing something.
10:29When you don't get enough sleep or are just too tired,
10:33you get those dark circles around your eyes.
10:35Want to know why?
10:36The skin under the eyes is very thin,
10:39so blood vessels are very close to the surface there,
10:42and you can see any difference easily.
10:44If you have a lack of sleep,
10:47your skin gets paler,
10:48and the blood vessels are even more visible,
10:51so you can see those dark circles showing through the skin.
10:54Also, with age, the skin naturally gets thinner,
10:58so that's why older people tend to have dark circles.
11:01But if you're young,
11:03just try to get more sleep.
11:06Let's pay a bit of attention to backpacks.
11:09They have a few interesting features.
11:11First, some of them have sternum straps,
11:14and they are quite helpful.
11:16They allow you to redistribute the weight of the backpack a bit,
11:19lifting some of it from your shoulders.
11:21Not much, but just enough to make your backpack lighter and easier to carry.
11:27And, of course, the sternum straps prevent the shoulder straps from sliding off.
11:33Okay, the next thing is gear loops.
11:36And probably from the name of it,
11:38you already have an idea of what you need them for.
11:41You can strap in some useful gear you need with you,
11:44like trekking poles or shovels.
11:46Some gear will need to be secured to do it.
11:49Drop the handle through the loop and rotate it upward.
11:52Then, secure it with the elastic hook at the top,
11:55and you're golden.
11:57And, yes, all backpacks have loops.
12:00Actually, I never thought of their purpose until today.
12:03Some people say that if you slide your thumbs through them,
12:06it makes the backpack sit tighter on your back,
12:09making it more comfortable.
12:11Other people just rest their hands there,
12:14but the reason why they're there
12:15is probably to prevent the ends from sliding back from the buckles.
12:19That would be quite a headache to slide them back all the time, right?
12:25Okay, let's look into some other ordinary stuff
12:28we've never paid attention to.
12:30Let's take, for example, jeans.
12:33They have those metal rivets.
12:35It turns out that they've been there as long as jeans exist.
12:39Jacob Davis, the man who made the first pair of jeans,
12:43added copper rivets to places where the pants were more likely to rip
12:46to make them stronger.
12:49So, it was a crucial detail to keep jeans together.
12:52Today, they have a more decorative purpose
12:55because they're distinctive and traditional for jeans.
13:00Also, many zippers have the letters YKK engraved on them.
13:05Those are the initial letters of Yoshida Kogyo Kabushiki Gaisha.
13:09It's the name of a Japanese company
13:11that can be translated as
13:13Yoshida Manufacturing Shareholding Company.
13:15It's the largest zipper manufacturer in the world,
13:20so all zippers produced by them are marked with these letters.
13:24It's estimated that the company produces half of all zippers in the world.
13:29That's why you see their zippers more often than any others.
13:35Have you noticed that canned and bottled soda seems to taste different?
13:40You're not wrong.
13:41That's actually true, and there's even science behind it.
13:45Chemists say that aluminum cans have a polymer layer
13:48that absorbs some of the soda's taste,
13:50so cans indeed change the taste.
13:54Chemicals in a plastic bottle can add some acetyl-dehyde,
13:57a by-product that gets formed while plastic is melted, to the drink.
14:01So, they also change the taste a bit.
14:04You never really drink the original drink.
14:07If you want to try the real thing,
14:09buy sodas in glass bottles.
14:12When soda is stored this way,
14:14its taste is the most similar to the original one.
14:19Plastic bottles with soft drinks have five bumps on the bottom,
14:23and water and juice plastic bottles have almost flat bottoms,
14:26except for a little kink.
14:28It's not random.
14:29A plastic bottle is made by putting a plastic tube into a mold
14:34and blowing some air inside to make it expand
14:37until it takes the needed shape.
14:39The problem is that at the bottom,
14:42the bottle will always have an outward kink
14:44that will make the bottle unstable.
14:47To avoid it, some air is also pushed inward from the bottom,
14:52creating that small punt at the base of it.
14:54Flat bottle bottoms are common
14:57because they need less plastic to be made,
15:00but soft drinks and sparkling water need special treatment.
15:04These liquids have internal pressure
15:06that can push the plastic outward,
15:08messing up with the punt and the stable form of a bottle.
15:12So, soda bottles have a curved shape
15:15because this way they're more pressure-resistant.
15:20Compare folding a regular piece of paper to folding a paper too.
15:24The latter will have more resistance.
15:26In the same way, curved plastic is more resistant to any pressure.
15:33Take a closer look at your bag of chips.
15:35You can probably find these little colored circles.
15:39They're made by the manufacturer
15:41to test the print that is used on the package.
15:43They're called color control patches.
15:47The circles are not the same palette as the final package.
15:50They're layered on top of each other
15:52to achieve the final color of the bag.
15:55So, why do manufacturers need them again?
15:59Imagine that something is off
16:00and the printing machine prints a bunch of wrong packages.
16:04That's a lot of wasted money.
16:06So, these control patches are there
16:09to make sure that the final print is going to be correct.
16:11If they're off, the manufacturer will know
16:14that the whole package is going to be off too.
16:18These patches allow the printers to find a surplus
16:21or a deficiency of color and solve the issue.
16:25But don't worry if you don't find these circles.
16:27They probably just got cut off.
16:31Take a good look at a milk jug.
16:33There's often an inverted circle on one of the sides.
16:37This dimple is there to make the jug more resistant
16:40and to prevent it from rupturing
16:42if the jug falls on the floor.
16:45The dimple gives some more space
16:47for the liquid to expand.
16:49Also, as the expiration date approaches,
16:52the microbes in the milk start to expel some gases.
16:56As more and more of them get trapped inside,
16:59the pressure in the jug rises.
17:01The dimple accommodates the expansion
17:03and prevents the jug from bursting.
17:10The Queen's Guard all appear to have the same uniform
17:13with a shared role of standing stoically for a long time.
17:16But if you look closely at their hats,
17:19there are five different types.
17:22The Grenadier has a white plume.
17:24The Coldstream has a red one.
17:26The Irish, a blue plume.
17:28The Welsh, green and white.
17:30And the Scots Guard has none.
17:33Their different divisions perform similar ceremonial duties
17:36at Buckingham Palace.
17:38But they have other actual roles as well,
17:41suited to their specialization.
17:44When peeling your boiled eggs,
17:46you can see a hidden layer under the shell.
17:48These two membranes, an inner and outer one,
17:51are made from the same stuff as your hair, keratin.
17:54It protects the inside from bacteria
17:56and stops liquids from escaping.
17:58You use X in your texts, which represents a kiss.
18:02It's been used this way for a very long time.
18:05Its original purpose dates back to the Middle Ages,
18:07where it was a representation of a person's faith,
18:10honesty and sincerity.
18:13Those that would sign off with an X
18:15would kiss it after signing as a display of a sworn oath.
18:20The X's meaning later changed to represent the action of kissing.
18:24And the first document showing this
18:26was a letter dating back to 1763,
18:29written by a naturalist, Gilbert White,
18:31who sent it to his wife.
18:34William Shakespeare is a name familiar to everyone.
18:37However, we don't know whether this was the actual way
18:40his name was spelled,
18:41and neither did he.
18:44He signed 80 different variations of his name's spelling
18:47on all his works.
18:49Historians haven't a clue which the correct spelling is.
18:52The version that we know of
18:53was only used on two of his plays.
18:57Different forms of alarm clocks
18:59were invented as far back as 348 BCE,
19:03with many versions throughout the world,
19:05all with complicated mechanics.
19:08Unaffordable to mostly everyone,
19:10they didn't catch on.
19:11Alternate methods to wake up in the morning
19:13started to be used in the 1800s.
19:16One process involving knocker-uppers
19:19was common in some countries.
19:21A person visited your house every morning
19:23to knock on your door four times.
19:27Inventor Antoine Rédier
19:28felt that he should be woken
19:30only when he felt it necessary.
19:32So, in 1847,
19:34he invented the first adjustable alarm clock.
19:38Tennis balls in Wimbledon
19:39must be kept at a perfect temperature
19:41to ensure they bounce at a consistent level.
19:45They're stored at 68 degrees Fahrenheit,
19:47so they're cold enough that the molecules
19:49inside the ball shrink,
19:51ensuring they bounce lower.
19:53Then, they're continuously swapped
19:55throughout a match
19:56as they expand by being hit too much,
19:58becoming too bouncy.
20:00Wimbledon goes through 50,000 tennis balls each year.
20:05You enjoy the smell of a freshly mowed lawn
20:08as you associate it with the weekends and summer.
20:11But that smell is a sign of stress
20:14made by the grass.
20:16Grass evolved to emit various elements
20:18when being eaten by bugs.
20:20This signal attracts predator insects to remove them.
20:23But unfortunately for the grass,
20:25there's nothing large enough to deter a lawnmower.
20:29There is no oxygen inside your packet of chips.
20:32If there was,
20:34it would influence the combination of molecules
20:36forming inside,
20:37spoiling the chips faster.
20:39The packets are instead filled with nitrogen,
20:42which pushes oxygen out.
20:43And this extends the shelf life
20:45and quality of your chips.
20:49You're traveling by plane overnight
20:51and just can't get to sleep.
20:53And the first night in a hotel wasn't great,
20:56regardless of how comfy the bed was.
20:58This is because of a human evolutionary trait
21:01called the first night effect.
21:04When you sleep in a different place than your home,
21:07the left side of the brain
21:08responds to more sounds while you're asleep.
21:10It continues to analyze your surroundings
21:13without you realizing,
21:14acting as though it's on a night watch
21:16and keeping you alert for any potential dangers.
21:20Most animals have this trait,
21:22although it's a lot more subtle in humans.
21:25But it's still effective enough
21:26to make sure you get your peanuts.
21:30Before playing basketball with hoops,
21:32you would have instead been playing with peach baskets.
21:34When the game was invented in 1891,
21:37a peach basket was used
21:39with the bottom of it cut off.
21:40But it only took 15 years
21:42for players to grow tired
21:43of constantly collecting the jammed balls
21:46and to remove the basket altogether.
21:49When you click your fingers,
21:51the snapping sound isn't from the physical click
21:53of finger and thumb.
21:54The noise actually comes from the finger hitting the palm.
21:59The instant film for the first Polaroid cameras
22:02didn't have their own coating after taking a photo.
22:05To develop it, you applied it yourself.
22:08Waiting for it to dry took a long time,
22:10so shaking it sped up the process.
22:12Then, from the 1970s,
22:14the film provided everything required
22:16for the photo to develop,
22:18making the popular craze of shaking Polaroids pointless.
22:22Shaking the photo can cause the ink to wave
22:24or blur before drying properly,
22:26so you shouldn't actually shake it
22:28like a Polaroid picture.
22:29And just wait patiently instead.
22:33Bug spray doesn't repel all bugs,
22:35especially the worst of them all,
22:37mosquitoes.
22:38It does cover the scent of carbon dioxide,
22:41which is what attracts mosquitoes.
22:43But the spray only protects you
22:45for a short distance.
22:47Mosquitoes can also track carbon dioxide
22:50over long distances.
22:51They will continue to stalk you
22:53until they find a gap in your invisible bug shield.
22:56A great alternative is lavender,
22:58which contains linalool.
23:00This fragrance completely overloads
23:03the mosquito's senses,
23:04making it unable to track you.
23:06The half belt on the back of some jackets
23:09appear like a fashion accessory.
23:11It was initially designed that way
23:13for larger jackets,
23:14as they could also be used as a blanket
23:16to wrap around oneself.
23:18The belt's position helps hold the material together,
23:21so it's easier to walk with
23:23whilst keeping you warm.
23:25Ketchup wasn't originally intended
23:28to be your favorite condiment.
23:30In 1834, a physician, John Cook,
23:33sold ketchup as a cure for indigestion.
23:36It was an immediate hit,
23:38and today, 10 billion ounces
23:40are purchased annually in the USA,
23:43although not as the intended medicine.
23:46Thomas Edison made over 1,000 inventions,
23:50and one in particular,
23:51the light bulb,
23:52is most famously linked to him.
23:54However, he didn't actually invent it.
23:57Warren Delarue, a British chemist,
23:59had solved this scientific challenge
24:0140 years earlier.
24:03There were also 20 other inventors
24:05who made alternate versions
24:06before Edison did.
24:08But earlier varieties relied on cotton thread
24:11and only lasted up to 14 hours.
24:14Edison, in 1880,
24:16used a carbonized bamboo thread instead,
24:18and his worked up to 1,200 hours.
24:21It became the most commercially viable light bulb,
24:24and today's ones are similarly shaped
24:26to Edison's original.
24:29The first treadmill was used in England in 1818.
24:32It was a large wooden cylinder with a handrail,
24:36although it wasn't used to keep fit.
24:39Convicted criminals would be forced to use these
24:41for up to 10 hours per day as a punishment.
24:45The energy output potential was realized,
24:47and soon it was built to work with water pumps
24:50and grain grinders.
24:52It was so effective that it was used
24:54in all prisons throughout the country.
24:56But in 1902, it was decided
24:58that it was too harsh and stopped.
25:00And now, this cruel punishment
25:02is mainly found in gyms.
25:05During the 1940s, there was a shortage of cocoa,
25:08and it was important to find a solution
25:10to this problem.
25:11A production company found a way
25:13by mixing only a small amount of cocoa
25:16with hazelnuts and milk,
25:17and the original Nutella was created.
25:20It started out as a loaf spread,
25:23like a stick of butter.
25:24It then transformed into a creamier version
25:26inside a jar in 1951.
25:29But it wasn't until 1964
25:31that it was given its famous name.
25:34Your passport might be a dark shade
25:36of either green, blue, or red.
25:39The darker color not only makes them appear
25:41more official, but is intended so that
25:44through its journeys,
25:45the dirt that's collected is more easily hidden.
25:49Wasabi was first used back in the 8th century.
25:52It wasn't meant as a spicy condiment
25:55as it's served with sushi today.
25:57Initially, it was used for its antimicrobial properties
26:00that help avoid the harmful reactions
26:02to fish with sushi that's a bit too old.
26:08Now, here's a trick.
26:10Instead of putting the box grater vertically
26:12on top of a plate,
26:13put it horizontally,
26:14with no plate underneath, of course.
26:16This way, you won't risk scraping your knuckles,
26:19because only your fingertips
26:20will eventually touch the grater
26:22when you reach the end of the process.
26:24Also, it gives the grater more stability,
26:26when otherwise, you'd have to balance the grater
26:29or even hold it in the air with the other hand.
26:31When you're done,
26:32or when there's just too much grated stuff
26:34on the bottom wall of the grater,
26:36simply turn it on its side
26:38to pour the contents into the bowl or plate.
26:41Flowers in a vase would stay fresher for longer
26:43if not for the bacteria that breed in the water.
26:46Since copper has some antibacterial properties,
26:49dropping a penny into the water
26:51will help keep the microbes at bay
26:53and let you enjoy your flowers
26:54for that little bit longer.
26:56An easy way to check
26:57if your bed linen has dried completely
27:00is to put a small mirror
27:01in between the layers for about 5 minutes.
27:04If the mirror has steamed up
27:06when you pick it up,
27:06it means the sheets are still a bit damp.
27:09Let them dry until the mirror
27:10stops getting cloudy.
27:12A damp bed is a lovely breeding ground
27:14for fungi and bacteria.
27:17Okay, I'm in.
27:18If you have a not-very-healthy
27:21habit of eating in front of your computer,
27:23you'll be surprised
27:24at how much crumbs and grime
27:26there is inside your keyboard.
27:28Now, you can just turn it over
27:30and shake it vigorously, of course.
27:32But that's not very good
27:33for any piece of tech, you know.
27:35So instead, take a post-it note
27:38and run its sticky part over the keyboard.
27:40It will collect the little pieces of trash
27:42like magic.
27:43Even a better way to do it, though,
27:45is to take a slime
27:46and stick it to the keyboard.
27:48Then take it away, squeeze it,
27:50and stick again in another part.
27:52The slime will fill the entire space
27:54between the keys,
27:55and its sticky properties will let it gather
27:57every little bit of garbage.
28:00Separating egg yolks from whites
28:01is easier using a plastic bottle.
28:04Break the necessary number of eggs
28:06into a bowl,
28:07and then take an empty plastic bottle
28:09and squeeze it.
28:10Hold the bottle over the yolk
28:11and release.
28:12It'll pull in air and the yolk together,
28:15leaving the white in the bowl.
28:17Repeat with the rest of the yolks,
28:18and you're done!
28:19And that's no yolk!
28:22If you're tired of spitting out the stones
28:24when eating cherries
28:25or want to make a cherry pie,
28:27push the stones out with a straw.
28:29Also, many garlic presses
28:31have a special tool on their handle
28:33that can be used exactly for that.
28:36Cleaning a blender can be a nuisance
28:38if you do it manually.
28:39Instead, fill it with hot water
28:41and add some liquid soap or detergent,
28:43then run it for about 10 seconds.
28:45Rinse it afterwards,
28:46and it's clean.
28:48Plaster walls can crumble, flake,
28:50and spread dust all over the floor
28:52when you hammer nails into it.
28:53Cut a strip of masking tape
28:55and stick it to the place
28:57you want to hammer a nail in.
28:59The tape won't let the plaster
29:00crack and crumble,
29:01leaving the hole neat and clean.
29:04Small scratches and dents
29:05on wooden furniture
29:06can be removed
29:07with some toothpaste or a walnut.
29:10For toothpaste,
29:11rub a pea-sized amount of it
29:13into the scratch until it's gone,
29:14then wipe the leftovers
29:16with a damp cloth.
29:17For a walnut,
29:18take a half of that brain-shaped nut
29:21and rub it into the dent.
29:22Then rub the area with your fingers
29:24and buff it with a soft cloth.
29:26This'll help the wood
29:27absorb the oil from the nut,
29:29making the scratch sealed and gone.
29:32The sticky residue on jars
29:34left after you removed the stickers
29:36won't be easily removed
29:37by water and detergent.
29:38So take some vegetable oil instead.
29:41Soak a cotton pad in it
29:43and wipe the sticky surface.
29:44Let it sit for a while
29:46and then wash the oil away
29:47together with the residue.
29:49If you can't comfortably
29:51reach the wick of a candle
29:52with a lighter,
29:53hey, take a stick of spaghetti.
29:55Light up its end
29:57and you'll get a burning stick
29:58that's easy to use
29:59for hard-to-reach places.
30:01Now, next time your razor blade's
30:03getting dull,
30:04try rubbing it backwards
30:05on a pair of jeans
30:07for regular upkeep.
30:08Not while you're wearing them,
30:09of course.
30:10Make sure you keep the blades dry, too,
30:12or even kept in mineral oil.
30:14That'll stop them from rusting.
30:16Keep all those jelly, ketchup,
30:18peanut butter, and mayo
30:19fresher for longer in your fridge
30:21by turning the contents upside down.
30:24This creates a partial vacuum
30:26inside the container,
30:27helping prevent mold growth.
30:29Storing ice cream upside down
30:31will prevent freezer burn, too.
30:33To bring your permanent marker
30:35back to life,
30:36simply put a few drops
30:37of rubbing alcohol
30:38into the felt material
30:39inside and shake.
30:41Once the felt absorbs
30:42the rubbing alcohol
30:43for a couple of minutes,
30:45the marker will be
30:46almost as good as new.
30:48Now, don't keep throwing away
30:49lettuce that goes black
30:51too quickly.
30:52Covering it with a dry paper towel
30:54and then placing it
30:55in an airtight container
30:56will help it keep fresher
30:57for much longer.
30:58This goes for any leafy greens
31:00you've got leftovers of.
31:02That sharpish bit
31:04sticking out of the cap
31:05of your favorite cream
31:06is there for a reason.
31:08These tubes are usually
31:09sealed with foil,
31:10so unless you love
31:11breaking your nails
31:12trying to open them,
31:13just flip the cap over
31:14and push.
31:16Your bobby pins
31:17might not stay in place
31:18if the grooves
31:19aren't facing the right way.
31:21They should always be
31:22on the bottom,
31:23close to your head.
31:24Still coming loose?
31:25Well, put a squeeze
31:26of hairspray
31:27right onto the bobby pin
31:29before you put it
31:29in your hair.
31:30Now, your cotton rounds pack
31:32has those strings on it
31:33so you can hang it
31:34on a handy hook
31:35in the bathroom.
31:36But there's no need
31:37to loosen and tighten it
31:39back up every time.
31:40Check out the bottom
31:41of the pack.
31:42It has a perforated line.
31:44Tear it open carefully
31:45and you're good to go.
31:47Two zips too much?
31:49Maybe.
31:50But they come in handy
31:51as a clever
31:51anti-theft device.
31:53Just lock them together.
31:54Now, no one
31:55can open your backpack.
31:57Don't have a lock on you?
31:58You can also tie them together
32:00with some string
32:01or even just a paper clip.
32:03Anything to slow
32:04those pickpockets down.
32:06That tiny little button
32:07on the back
32:08of a shirt collar
32:08is used to hold
32:09your tie in place.
32:11Hey, you don't want
32:12your tie trying
32:13to escape back there.
32:15Shoe manufacturers
32:16care about their customers.
32:17So, most running shoes
32:19now have a special
32:20anti-blister system
32:21pre-installed.
32:23Sounds intense,
32:24but it's basically
32:25just that extra hole
32:26on top of your sneakers.
32:27Make a loop
32:28with the extra hole,
32:29inserting the lace backward.
32:31Cross your laces
32:32and put them
32:33through the loops.
32:34Now, pull the laces down
32:35to lock your foot in place.
32:37Now, run.
32:38Yeah, go ahead.
32:40Car headrests
32:41are all about comfort,
32:42and detachable headrests
32:43are all about safety.
32:45If you pull the headrest out,
32:47you'll see
32:47two sturdy metal bars.
32:49If you ever get locked
32:51or trapped in your car,
32:52you can use the bars
32:53to smash the window
32:54and get out.
32:56If you've got some
32:57pesky parsley
32:58stuck in your teeth,
32:59try this tip.
33:00It can be hard
33:01to get it out
33:01with loose floss.
33:02You need more tension,
33:04so just tie it in a knot.
33:06It's not an accident
33:08that soy sauce bottles
33:09have two spouts.
33:10The sauce is liquid,
33:11and it flows out of the bottle
33:13pretty easily
33:14once you turn it over.
33:15Most Asian food lovers
33:16have spilled it
33:17at least once in a lifetime.
33:19That's why nowadays,
33:20restaurants prefer
33:21serving soy sauce
33:22in special bottles
33:24that have two spouts.
33:25This design allows you
33:26to control
33:27when and how much
33:28sauce will come out.
33:29Just put your finger
33:30on one spout
33:31when you pour the sauce
33:32through another.
33:33If you press your finger
33:35tightly to the spout,
33:36the sauce will stop flowing,
33:37and if you remove your finger,
33:39it'll flow again.
33:41And don't forget
33:42to ask your server,
33:43Hey, wasabi!
33:45Alright.
33:46A hair straightener
33:47is an excellent tool
33:48not only for treating
33:49your natural curls,
33:50but also for fixing
33:52crumpled money
33:52or documents.
33:53You can also use
33:54a regular iron
33:55for this purpose.
33:56Just make sure
33:57you don't turn on
33:58steaming mode.
33:59Otherwise,
34:00there's a risk
34:00of damaging the paper.
34:02Hairbands are good
34:03not only for getting
34:04your hair done,
34:05but also to open
34:06a glass jar
34:07with canned food.
34:08Your hands might slip
34:09on the tightly closed lid,
34:11and if you don't open
34:12the can from the first attempt,
34:14your palms tend to get sweaty,
34:16making the task
34:17virtually impossible.
34:18So, put a hairband
34:20on the lid
34:21to fix your hand
34:22and make your grasp stronger.
34:24A simple rubber band
34:25will do as well.
34:26Now, it's time
34:27to take my sweaty palms
34:29and go.
34:29Okay, I know
34:30it's kind of cold
34:31to the touch,
34:32especially on a
34:33freezing winter's day,
34:34but did you know
34:34that brass doorknobs
34:35actually serve a purpose
34:36apart from looking
34:37classy and shiny?
34:39Since it's a copper alloy,
34:40brass has antimicrobial
34:42properties.
34:42That means it can help
34:44get rid of harmful germs
34:45and bacteria,
34:46sometimes in up to
34:47two hours.
34:48In high-traffic areas,
34:50that's all the more useful,
34:51but since brass is
34:52much costlier than
34:53other metals like
34:54nickel and steel,
34:55you barely see
34:56these types of
34:57doorknobs anymore
34:58nowadays.
34:59Speaking of lovely
35:00multi-purpose items,
35:01most screwdrivers
35:02have a tiny little
35:03secret of their own.
35:04They can sometimes
35:05be slid through a wrench
35:06so that they can be used
35:07to create more torque
35:09when twisting,
35:09not to mention the uses
35:11when it comes to bolts
35:12in hard-to-reach places.
35:14There's a reason
35:15why buttons on
35:16women's shirts
35:17are for the left-handed
35:18and it has nothing
35:19to do with fashion.
35:20This practice dates
35:21back to the times
35:22when chambermaids
35:23were helping ladies
35:24dress themselves
35:25and it was easier
35:26for them to perform
35:27their job
35:28with this orientation.
35:29Having the buttons
35:30placed as such
35:32indicated a sign of wealth,
35:33so it's easy to imagine
35:35why the practice carried on,
35:36even though most people
35:38dress themselves nowadays.
35:39Next time you receive
35:40a package in your mail,
35:42take a look at
35:43your box cutter.
35:44If it features
35:45some diagonal lines
35:46on the blade,
35:46you're in for
35:47a little design perk.
35:48Turns out that
35:49these are blades
35:50that snap off.
35:52Continuously cutting cardboard
35:53can dull the sharp edge
35:54of the blade.
35:55To help prevent the need
35:56to buy a brand new
35:57box cutter,
35:58the top segment
35:58along the next line
36:00can be broken off
36:01to reach a new sharp edge.
36:03To do this,
36:04check out the small hole
36:05at the base of the tool,
36:06sometimes called
36:07the blade snapper.
36:09The people that first
36:10came up with this
36:11brilliant invention
36:11were engineers
36:12inspired by the way
36:13chocolate bars are segmented.
36:15Hold on a minute,
36:16don't throw away
36:17the cardboard package
36:18just yet.
36:19Most likely,
36:20you'll have some
36:20silica gel packets
36:21somewhere at the
36:22bottom of the box.
36:23Since this gel
36:24is basically a drying tool,
36:26it gathers up the moisture
36:27out of its environment,
36:28so you can store
36:29these packets
36:29for further occasions.
36:31Whether you'll need
36:32to dry out your phone
36:32or some other
36:33electrical object,
36:35you can place them
36:36in a container
36:36next to the silica gel
36:37to reduce the damage.
36:39You don't have to be
36:41a mechanic to know
36:42when a standard car tire
36:43needs replacing,
36:44since they come equipped
36:45with a neat indicator.
36:46Take a closer look,
36:48and you'll see
36:48that treads
36:49within the tire
36:50are a bunch
36:50of rubber notches.
36:52When the treads
36:53are evened out
36:54with the perpendicular bars,
36:55it's a sign you need
36:56to book an appointment
36:57with your local car service,
36:59since most likely
37:00the tires have lost
37:01most of their traction
37:02and may not be safe
37:03for driving any longer.
37:05The upper corners
37:06of a car windshield
37:07feature textured black dots
37:09melted into the glass edges.
37:11This neat add-on
37:12isn't there
37:12for design purposes.
37:13It's called
37:15frit glazing,
37:16which means
37:17that a special type
37:18of ceramic paint
37:19is added to the window
37:20for protecting its sealant
37:22from UV rays.
37:23It also conceals
37:25and creates
37:26a coarser surface
37:27for the adhesive used
37:28to set the window
37:29in place.
37:30Whenever you're up
37:31for a drive,
37:32check out
37:33if there's a small tab
37:34under your car's
37:35rear-view mirror.
37:36Bet you didn't know
37:38it's there
37:38to help switch the mirror
37:39from daytime
37:40to nighttime views.
37:42It uses a prismatic
37:44glass technology
37:45to blur the reflection
37:46and reduce the glare
37:47of headlights
37:48behind you
37:48in traffic.
37:50People came up
37:51with these manually
37:51tilted mirrors
37:52in the 1930s,
37:53but they became
37:54standard somewhere
37:55in the 1970s.
37:57While you're in the car,
37:58check out the headrests
38:00as you most likely
38:01don't know
38:01that they carry
38:02a little disguised purpose.
38:04Of course,
38:05they're adjustable
38:05to accommodate passengers
38:07of any height
38:07so that they get
38:08the proper support
38:09for their heads and necks.
38:10The hidden feature
38:11is that they are
38:12detachable
38:13and come with
38:14two very solid
38:15metal bars.
38:16Should you ever
38:17find yourself
38:18stuck in a car
38:19and need to make
38:19a fast getaway?
38:21These bars come in handy
38:22to crack out
38:23the car windows.
38:24So you're out
38:25for a drive
38:26and you're suddenly
38:27out of gas.
38:28What I'm about
38:29to describe
38:29sounds more like
38:30a meme
38:30than an actual
38:31situation bound
38:32to happen.
38:32But what if
38:34you're in such a hurry
38:35that you accidentally
38:35drive off
38:36with the gas nozzle
38:37still in the tank?
38:38Well,
38:40the nozzles
38:40have been designed
38:41to prevent
38:41any hazards
38:42from happening,
38:43rest assured.
38:44They feature
38:45a breakaway device
38:46that will allow
38:46the hose to separate
38:48when taken out
38:48with enough force.
38:50Initially designed
38:51in the early 20th century
38:53to be worn
38:53exclusively
38:54by basketball players,
38:56sneakers soon became
38:57one of those
38:57fashion fundamentals
38:59similar to jeans
39:00and leather jackets.
39:01If you take
39:02a closer look at them,
39:03you'll see they have
39:03two extra holes
39:04on the side
39:05similar to the
39:06shoelace holes.
39:07They're manufactured
39:08as such not only
39:09to provide extra
39:10ventilation but to
39:11allow people to get
39:12extra creative
39:13with their laces
39:14when wearing the shoes.
39:15Admit it,
39:16you've always thought
39:17that chopsticks
39:18are merged at the end
39:19for the sole purpose
39:20of keeping them together
39:21until you're ready
39:22to dig into your meal.
39:23That may or may not
39:24be the whole truth.
39:26Under a more
39:27detailed inspection,
39:28the wooden tools
39:29feature a square-shaped end.
39:31Chopsticks manufactured
39:32like this date back
39:33to an old Japanese
39:34traditional design
39:35which can help
39:36with breaking
39:37the ends easily.
39:38The separated end
39:40can then be used
39:41as a resting block
39:42for the chopsticks
39:42to keep it more sanitized
39:44in hopes it can be used again
39:45since they won't be
39:47touching the table
39:47or any other surface.
39:50Women's bikes
39:50have a special design
39:52which, surprisingly,
39:53has a historical
39:54and fashionable purpose.
39:56The lower frame
39:57is for the most part
39:58meant to make up
39:59for the generally
39:59shorter height of ladies
40:00compared to that
40:01of the average gentleman.
40:03While that is the case
40:05for handlebars
40:05and saddles,
40:06the overall frame
40:07is lower
40:08for an additional purpose.
40:09Way back when women
40:10wore long skirts
40:11and dresses all day,
40:13every day they needed
40:14to make sure
40:14their outfits
40:15wouldn't get caught
40:16in the frame.
40:17That's how we came up
40:18with a lower-framed bicycle,
40:20perfectly made for women
40:21and their needs
40:22at the time.
40:24The fact that
40:25toothpastes
40:25are multicolored
40:27is not just a nice perk
40:28to make dental hygiene
40:29more fun.
40:30There's a secret meaning
40:31related to each of the colors,
40:32which dates back
40:33to the 1970s.
40:35In those days,
40:36people grew more
40:37and more interested
40:38in their oral health care
40:40and as such,
40:41they were looking
40:42for products
40:42which could do more
40:43than merely clean
40:44their teeth.
40:45One company
40:46was the pioneer
40:47in that regard,
40:48adding mouthwash
40:49to its toothpaste,
40:50meaning the blue strip.
40:51They later added on
40:53the red strip,
40:54meant to feature ingredients
40:55which helped
40:56with gum care.
40:57Speaking of toothpaste,
40:59check the cap
40:59next time you open
41:00a new tube.
41:01You may be in
41:02for a little surprise.
41:03There's a pointed cone shape
41:05inside the cap
41:06so you can puncture
41:07the seal of the toothpaste
41:08without cutting yourself
41:09or ruining your manicure.
41:11Not to mention,
41:12it's more hygienic
41:13since you won't be able
41:14to transfer germs
41:15or other bacteria
41:16into the product itself.
41:18On the subject
41:19of bathroom countertop items,
41:22toothbrushes come
41:22with a neat add-on
41:23hidden in the bristle patterns.
41:25Apart from making
41:26the toothbrush look cooler,
41:27they also do come
41:28with a practical purpose.
41:31Most toothbrushes
41:32come with a pattern
41:32of blue bristles
41:33intertwined with white ones.
41:35The blue dye
41:36is meant to fade out,
41:37signaling the time
41:38when you need
41:39to replace your toothbrush.
41:41Dentists say
41:42that toothbrushes
41:43should be replaced
41:43every three to four months,
41:45but it does serve
41:46as a great reminder
41:47in case you forget.
41:48Still love playing with LEGO?
41:50Don't judge.
41:51Hey, it's a great hobby
41:52for all ages.
41:53Notice there's a hole
41:54on top of the LEGO heads.
41:56Behold,
41:57you're looking at
41:57a safety feature
41:58that the people at LEGO
41:59designed to prevent
42:01choking hazards.
42:02The most dangerous issue
42:04should a person swallow
42:05any of these pieces
42:06is the blocking
42:07of the airways.
42:08Designing a hole
42:10inside the LEGO head
42:11helps the air
42:12to flow freely
42:12through the piece
42:13until it can be
42:14removed safely.
42:16We're now used
42:17to all sorts
42:18of modern light bulbs,
42:19some tubular,
42:20some shaped like diamonds,
42:21and some even
42:22twisted all together.
42:24Historically,
42:25light bulbs were round
42:26and the initial shape
42:27served a purpose
42:28in itself.
42:29It was mainly connected
42:31to the fact
42:31that glass bulbs
42:32were hand-blown,
42:33which gave them
42:34the round shape
42:34to begin with.
42:35The hidden practical reason
42:37was that the light bulb filament
42:38needed to be
42:39at the same distance
42:40from every surface
42:41of the glass sphere.
42:42The easiest way
42:44to achieve this
42:44was to make the glass
42:45in the shape of a globe.
42:49You just spent
42:50the entire morning
42:51running errands
42:52up and down the street,
42:53and you finally stopped
42:54to treat yourself
42:55to a cup of coffee.
42:56You enter
42:57the nearest coffee shop,
42:58place your order,
42:59and notice that,
43:00actually,
43:01you really need
43:02to use the bathroom.
43:03It's a regular-looking
43:04public one
43:05with multiple stalls.
43:06As you pick yours,
43:08the one in the middle,
43:09you get inside,
43:10and your mind
43:11starts to wander.
43:12Why on earth
43:13do bathroom doors
43:14have a half-inch gap
43:15between the door
43:16and the lock?
43:17And why on earth
43:18do they have
43:18a huge gap
43:19between the door
43:20and the floor?
43:21Can we have a drumroll
43:22for this moment, please?
43:24Well, my friend,
43:25there is not only
43:26one specific reason
43:27why public bathroom doors
43:29have so many gaps in them,
43:31but rather several.
43:32Public toilets
43:33are designed
43:34to make people spend
43:34as little time
43:36there as possible.
43:37You aren't supposed
43:37to feel comfortable
43:38or at home.
43:40So, the design
43:41would have to reflect
43:41this notion.
43:42Here come the gaps.
43:44In some bathrooms,
43:45gaps are so big
43:47that users
43:48may even feel
43:48self-conscious
43:49about doing their business
43:51out of preoccupation
43:52that the rest of the people
43:53standing in line
43:54will see them.
43:55Then, there's
43:56the matter of pricing.
43:58Making custom doors
43:59can be a heavy burden
44:00for the people
44:01building public toilets.
44:02This would mean
44:03understanding
44:04exact measurements
44:05so that doors
44:06would always fit
44:07the mold of the stalls
44:08it's supposed
44:08to be installed into.
44:10Now, not all the gaps
44:11in public bathrooms
44:12are necessarily
44:14the same size.
44:15They may vary,
44:16even if this variation
44:17is small
44:18and often unnoticeable.
44:20So, these gaps
44:21actually help
44:22to reduce the margins
44:23of errors
44:23and to turn production
44:25more cost-effective
44:26for the people
44:27financing them.
44:28In case a door
44:29comes wider
44:30or more narrow
44:31than it should,
44:32the gap regulates
44:33the differences
44:33and allows for
44:34their installation anyway.
44:36There is also
44:37the case of air circulation.
44:39The last thing
44:40you want to do
44:41in a public bathroom
44:41is to trap odors.
44:43So, you need
44:44a little space
44:45under and between
44:46the doors
44:46to allow the air
44:47to flow.
44:48Finally, the gaps
44:50are a big safety measure.
44:51It can always allow
44:52for people on the outside
44:53to see if someone
44:54inside a stall
44:55isn't feeling too okay
44:57and maybe
44:58needs some help.
44:59And what about
45:00that extra hole
45:01in the upper part
45:02of the sink?
45:03It has a name
45:03in everything.
45:04The overflow hole.
45:06And it's designed
45:07to keep the sink
45:08from flooding.
45:08So, in case
45:09someone forgets
45:10and keeps the faucet
45:11going for too long
45:12or the sink
45:13gets clogged
45:14and water
45:15can't drain down
45:15from the main drain hole,
45:17the overflow hole
45:18comes in
45:19to save the day.
45:20Let's say it
45:21buys you a little time
45:22before you have
45:23the entire bathroom
45:24floor flooded.
45:25Have you ever noticed
45:26how satisfying
45:27closing the door
45:28of a car can be?
45:29Car manufacturers
45:30devote a great deal
45:32of time
45:32to designing
45:33these sounds.
45:34Studies have shown
45:35that they create
45:35a perceived sense
45:36of quality
45:37in the buyer.
45:38It all begins
45:39with the primary material.
45:41While older cars
45:42used to be made
45:43with heavier materials,
45:44car doors nowadays
45:45are produced
45:46with lighter tin,
45:47which can make
45:48a rather unpleasant
45:49metallic sound
45:50once you shut
45:51them closed.
45:52So, car companies
45:53employ sound engineers
45:54to ensure
45:55that there is
45:56the exact amount
45:56of foam,
45:57mats,
45:58and tin
45:58in a car's composition
45:59to make the most
46:01comforting sound possible.
46:02And what about
46:03those tiny dots
46:05on the top
46:05of your car's
46:06front window?
46:07The pattern
46:07of these little
46:08black dots
46:09minimizes distractions
46:10for your eyes.
46:11This black part,
46:12also known as frit,
46:14normally gets warmer
46:15than the clear parts,
46:16which prevents
46:17the windshield
46:18from deforming.
46:19And no,
46:20the tab under
46:21your rearview mirror
46:22is not made only
46:23for the purpose
46:23of hanging fluffy dice
46:25or aromatic-pleasing
46:26air fresheners.
46:27It's actually a switch
46:28that allows you
46:29to adjust the position
46:30of the mirror
46:31depending on the time
46:32of day.
46:33Flip it one way
46:34and it's the daytime
46:35driving mode.
46:36Flip the other
46:37and you're ready
46:37to drive safely
46:38during nighttime
46:39as it tones down
46:40the glare coming
46:41from headlights
46:42of the cars behind you.
46:44Next time you head
46:45out to the supermarket,
46:46make sure to keep
46:47this in mind.
46:48In case you don't
46:49have a coin
46:49to unlock these
46:50shopping carts,
46:51there is a well-kept
46:52secret that can
46:53help you out.
46:54If you have your
46:55house keys on you,
46:56check for a rounded
46:57key head.
46:58If you happen to find
46:59one, try using it
47:00to unlock the cart.
47:01It should fit
47:02perfectly in there,
47:04replacing the need
47:04to carry coins around.
47:06Because, if we're
47:07being honest,
47:07who still has them?
47:09Elevators.
47:10If you want to ride
47:11them on your terms
47:12and your terms only,
47:13make sure to try
47:14something out.
47:15Most elevators
47:16have a secret
47:17button combination
47:18you can use to skip
47:19all the other
47:20selected floors
47:20and go directly
47:21to the one
47:22of your choosing.
47:23This might work out,
47:25especially on those
47:26days when you've
47:26pressed 13.
47:27But you wanted
47:28to press 33.
47:29On most elevators,
47:31this works once you
47:32simultaneously press
47:33the closed door button
47:34together with your
47:35floor number.
47:36This should help you
47:37get to your floor
47:38without stopping.
47:39Some elevators
47:40require you to
47:41double-press the
47:42selected floor numbers,
47:43as double-pressing
47:44will often cancel
47:45the previously made
47:46request.
47:47While other elevators
47:49require you to
47:49hold the open door
47:51button and then
47:52double-press the
47:52buttons of the
47:53floors you'd like
47:54to cancel.
47:55Now, to stay out of
47:56trouble, it's best not
47:57to cancel the floors
47:58of the other people
47:59in the elevator.
48:00They won't take it
48:01kindly.
48:02Also, keep in mind
48:03that there are elevators
48:04that might not have
48:05this function.
48:06Now, for honey lovers
48:07out there, go ahead
48:08and raise your hand.
48:09If your pot of golden
48:11honey is crystallized,
48:12know that it is
48:13actually a good sign.
48:16Crystallized honey
48:16means that it hasn't
48:17been pasteurized,
48:19which means better
48:19product quality.
48:21With a decrease in
48:22temperature, the natural
48:23ingredient of honey,
48:24also known as
48:25glucose, will make
48:27it crystallize.
48:28Now, try making the
48:29best of it.
48:30To add some texture
48:31to your oatmeal or
48:32toast, add a layer of
48:33crystallized honey and
48:34enjoy nature's sugar.
48:36And if you don't like
48:37crystallized honey,
48:38plop it in the
48:39microwave for a minute
48:40or two.
48:41Ah, winter and fall.
48:43You know what this
48:44means, right?
48:44Sweater weather.
48:45But there's nothing
48:47more annoying than
48:47wearing your beautiful
48:49wool sweater and
48:50itching yourself all the
48:51way through it.
48:52Actually, I can be more
48:54annoying than that,
48:55but let's talk about
48:56itchy sweaters.
48:57To keep this from
48:57happening again,
48:58here's the secret.
48:59Turn your sweater
49:01inside out and soak
49:02it in cold water.
49:03Add two or three
49:04tablespoons of vinegar
49:05and let it sit for a
49:07while.
49:07Then, drain the water.
49:09Now, while the sweater
49:10is still wet,
49:11massage a generous
49:12amount of hair
49:13conditioner into the
49:14fibers of the wool.
49:16After letting it soak
49:17in the hair conditioner
49:18for about 30 minutes,
49:19gently press the excess
49:21water out of the wool
49:22and leave it to dry
49:23flat on a towel.
49:25There you go!
49:26No more itchy sweater.
49:28Any fast food
49:29restaurant you go to
49:30will hand out
49:30small paper cups
49:32for customers to fill
49:33with their ketchup,
49:34mustard, or
49:34barbecue sauce.
49:36But if you're eating
49:37some chicken nuggets
49:38or trying to dip
49:39your burger into the
49:40cup, there's always
49:41that bit of sauce
49:42that seems impossible
49:43to reach.
49:44Next time,
49:45try unfolding the
49:46cup.
49:47It'll turn into
49:48a small paper plate
49:49and this way,
49:50you'll get all
49:51the ketchup you
49:51poured in the
49:52first place.
49:54Padlocks used
49:55in outdoor environments
49:56should be clean
49:57and lubricated
49:58every three months.
49:59Regular lubrication
50:00will help prevent
50:01padlocks from freezing
50:03in cold weather
50:03conditions.
50:04Look for the tiny hole
50:06on the bottom
50:06of the lock.
50:07Then, pour oil
50:08into it,
50:09and there you go!
50:10It opens again!
50:12One thing we often
50:13neglect is a point
50:14in an ointment cap.
50:16These pointy surfaces
50:17were designed to help
50:18us break the tinfoil
50:19protection of the
50:20ointment tube.
50:21You just turn the cap
50:22over and break the
50:24ointment seal with its
50:25own cap, and there you
50:27go!
50:28After a long day of work,
50:29all you really need to
50:31do is a bubble bath.
50:32You turn on the hot
50:33water and let it run
50:34for a few minutes.
50:35You might even light a
50:36candle and pour some
50:37essential oils into
50:38the water.
50:39Then, in comes the
50:41liquid soap.
50:42You stir the water
50:43until the entire surface
50:44of the tub water is
50:45crammed with bubbles
50:47and make your way in.
50:48The bubbles in a
50:49bubble bath have a
50:50fundamental primary
50:51function.
50:52Their job is to
50:53preserve the water's
50:54temperature, just so
50:55you can have warm
50:57water for longer.
50:58Do you have sweaty
50:59feet?
51:00Weird question, I know.
51:01But if you're one of
51:02these people, here's
51:03some good news.
51:05All is not lost.
51:06Try putting a dry
51:07teabag inside your
51:09shoes and storing it
51:10in a dry place for a
51:11while.
51:12The teabags will
51:13absorb the humidity
51:14and the smell off the
51:15soles of your shoes.
51:17So, here I am
51:18thinking, shouldn't we
51:19have learned these
51:20things in school?
51:21Well, either way, if
51:22you learned something
51:23new today, make sure
51:24to tell us about it in
51:25the comments below.
