00:00Now here's a trick. Instead of putting the box grater vertically on top of a plate, put it horizontally, with
00:06no plate underneath, of course.
00:08This way, you won't risk scraping your knuckles, because only your fingertips will eventually touch the grater when you reach
00:14the end of the process.
00:15Also, it gives the grater more stability, when otherwise you'd have to balance the grater or even hold it in
00:21the air with the other hand.
00:22When you're done, or when there's just too much grated stuff on the bottom wall of the grater, simply turn
00:28it on its side to pour the contents into the bowl or plate.
00:32Flowers in a vase would stay fresher for longer if not for the bacteria that breed in the water.
00:37Since copper has some antibacterial properties, dropping a penny into the water will help keep the microbes at bay and
00:44let you enjoy your flowers for that little bit longer.
00:47An easy way to check if your bed linen has dried completely is to put a small mirror in between
00:53the layers for about 5 minutes.
00:55If the mirror has steamed up when you pick it up, it means the sheets are still a bit damp.
01:00Let them dry until the mirror stops getting cloudy.
01:03A damp bed is a lovely breeding ground for fungi and bacteria.
01:08Okay, I'm in.
01:09If you have a not-very-healthy habit of eating in front of your computer, you'll be surprised at how
01:16much crumbs and grime there is inside your keyboard.
01:19Now, you can just turn it over and shake it vigorously, of course, but that's not very good for any
01:25piece of tech, you know.
01:26So instead, take a post-it note and run its sticky part over the keyboard.
01:31It will collect the little pieces of trash like magic.
01:34Even a better way to do it, though, is to take a slime and stick it to the keyboard, then
01:40take it away, squeeze it, and stick again in another part.
01:43The slime will fill the entire space between the keys, and its sticky properties will let it gather every little
01:49bit of garbage.
01:51Separating egg yolks from whites is easier using a plastic bottle.
01:55Break the necessary number of eggs into a bowl, and then take an empty plastic bottle and squeeze it.
02:01Hold the bottle over the yolk and release.
02:04It'll pull in air and the yolk together, leaving the white in the bowl.
02:08Repeat with the rest of the yolks, and you're done!
02:11And that's no yolk!
02:13If you're tired of spitting out the stones when eating cherries or want to make a cherry pie, push the
02:19stones out with a straw.
02:21Also, many garlic presses have a special tool on their handle that can be used exactly for that.
02:27Cleaning a blender can be a nuisance if you do it manually.
02:30Instead, fill it with hot water and add some liquid soap or detergent, then run it for about 10 seconds.
02:36Rinse it afterwards, and it's clean.
02:39Plaster walls can crumble, flake, and spread dust all over the floor when you hammer nails into it.
02:45Cut a strip of masking tape and stick it to the place you want to hammer a nail in.
02:49The tape won't let the plaster crack and crumble, leaving the hole neat and clean.
02:55Small scratches and dents on wooden furniture can be removed with some toothpaste or a walnut.
03:01For toothpaste, rub a pea-sized amount of it into the scratch until it's gone, then wipe the leftovers with
03:07a damp cloth.
03:08For a walnut, take a half of that brain-shaped nut and rub it into the dent.
03:14Then rub the area with your fingers and buff it with a soft cloth.
03:18This'll help the wood absorb the oil from the nut, making the scratch sealed and gone.
03:23The sticky residue on jars left after you remove the stickers won't be easily removed by water and detergent.
03:30So, take some vegetable oil instead.
03:32Soak a cotton pad in it and wipe the sticky surface.
03:36Let it sit for a while and then wash the oil away together with the residue.
03:41If you can't comfortably reach the wick of a candle with a lighter,
03:45hey, take a stick of spaghetti!
03:47Light up its end, and you'll get a burning stick that's easy to use for hard-to-reach places.
03:52Now, next time your razor blade's getting dull,
03:55try rubbing it backwards on a pair of jeans for regular upkeep.
03:59Not while you're wearing them, of course.
04:01Make sure you keep the blades dry, too, or even kept in mineral oil.
04:05That'll stop them from rusting.
04:07Keep all those jelly, ketchup, peanut butter, and mayo fresher for longer in your fridge
04:12by turning the contents upside down.
04:15This creates a partial vacuum inside the container, helping prevent mold growth.
04:20Storing ice cream upside down will prevent freezer burn, too.
04:24To bring your permanent marker back to life,
04:27simply put a few drops of rubbing alcohol into the felt material inside and shake.
04:32Once the felt absorbs the rubbing alcohol for a couple of minutes,
04:36the marker will be almost as good as new.
04:39Now, don't keep throwing away lettuce that goes black too quickly.
04:43Covering it with a dry paper towel and then placing it in an airtight container
04:47will help it keep fresher for much longer.
04:50This goes for any leafy greens you've got leftovers of.
04:53That sharpish bit sticking out of the cap of your favorite cream is there for a reason.
04:59These tubes are usually sealed with foil,
05:01so unless you love breaking your nails trying to open them,
05:04just flip the cap over and push.
05:07Your bobby pins might not stay in place if the grooves aren't facing the right way.
05:12They should always be on the bottom, close to your head.
05:15Still coming loose?
05:16Well, put a squeeze of hairspray right onto the bobby pin before you put it in your hair.
05:22Now, your cotton rounds pack has those strings on it,
05:25so you can hang it on a handy hook in the bathroom.
05:27But there's no need to loosen and tighten it back up every time.
05:31Check out the bottom of the pack.
05:33It has a perforated line.
05:35Tear it open carefully, and you're good to go.
05:38Two zips too much?
05:40Maybe.
05:41But they come in handy as a clever anti-theft device.
05:44Just lock them together.
05:46Now, no one can open your backpack.
05:48Don't have a lock on you?
05:50You can also tie them together with some string,
05:52or even just a paper clip.
05:54Anything to slow those pickpockets down.
05:57That tiny little button on the back of a shirt collar
06:00is used to hold your tie in place.
06:02Hey, you don't want your tie trying to escape back there.
06:06Shoe manufacturers care about their customers,
06:08so most running shoes now have a special anti-blister system pre-installed.
06:14Sounds intense, but it's basically just that extra hole on top of your sneakers.
06:19Make a loop with the extra hole, inserting the lace backward.
06:22Cross your laces and put them through the loops.
06:25Now, pull the laces down to lock your foot in place.
06:28Now, run.
06:29Yeah, go ahead.
06:31Car headrests are all about comfort,
06:33and detachable headrests are all about safety.
06:36If you pull the headrest out, you'll see two sturdy metal bars.
06:40If you ever get locked or trapped in your car,
06:43you can use the bars to smash the window and get out.
06:47If you've got some pesky parsley stuck in your teeth, try this tip.
06:51It can be hard to get it out with loose floss.
06:54You need more tension, so just tie it in a knot.
06:58It's not an accident that soy sauce bottles have two spouts.
07:01The sauce is liquid, and it flows out of the bottle pretty easily once you turn it over.
07:06Most Asian food lovers have spilled it at least once in a lifetime.
07:10That's why nowadays, restaurants prefer serving soy sauce in special bottles that have two spouts.
07:16This design allows you to control when and how much sauce will come out.
07:21Just put your finger on one spout when you pour the sauce through another.
07:24If you press your finger tightly to the spout, the sauce will stop flowing,
07:29and if you remove your finger, it'll flow again.
07:32And don't forget to ask your server,
07:34Hey, wasabi!
07:36Alright.
07:37A hair straightener is an excellent tool, not only for treating your natural curls,
07:42but also for fixing crumpled money or documents.
07:45You can also use a regular iron for this purpose.
07:47Just make sure you don't turn on steaming mode.
07:50Otherwise, there's a risk of damaging the paper.
07:53Hair bands are good not only for getting your hair done,
07:56but also to open a glass jar with canned food.
07:59Your hands might slip on the tightly closed lid,
08:02and if you don't open the can from the first attempt,
08:05your palms tend to get sweaty, making the task virtually impossible.
08:10So, put a hair band on the lid to fix your hand and make your grasp stronger.
08:15A simple rubber band will do as well.
08:17Now, it's time to take my sweaty palms and go.
08:20Okay, I know it's kind of cold to the touch, especially on a freezing winter's day.
08:25But did you know that brass doorknobs actually serve a purpose apart from looking classy and shiny?
08:30Since it's a copper alloy, brass has antimicrobial properties.
08:34That means it can help get rid of harmful germs and bacteria, sometimes in up to two hours.
08:39In high-traffic areas, that's all the more useful.
08:42But since brass is much costier than other metals like nickel and steel,
08:46you barely see these types of doorknobs anymore nowadays.
08:50Speaking of lovely multi-purpose items,
08:52most screwdrivers have a tiny little secret of their own.
08:55They can sometimes be slid through a wrench so that they can be used to create more torque when twisting.
09:00Not to mention the uses when it comes to bolts in hard-to-reach places.
09:05There's a reason why buttons on women's shirts are for the left-handed,
09:09and it has nothing to do with fashion.
09:11This practice dates back to the times when chambermaids were helping ladies dress themselves,
09:16and it was easier for them to perform their job with this orientation.
09:21Having the buttons placed as such indicated a sign of wealth,
09:24so it's easy to imagine why the practice carried on.
09:27Even though most people dress themselves nowadays.
09:31Next time you receive a package in your mail, take a look at your box cutter.
09:35If it features some diagonal lines on the blade, you're in for a little design perk.
09:39Turns out that these are blades that snap off.
09:43Continuously cutting cardboard can dull the sharp edge of the blade.
09:46To help prevent the need to buy a brand new box cutter,
09:49the top segment along the next line can be broken off to reach a new sharp edge.
09:54To do this, check out the small hole at the base of the tool.
09:57Sometimes called the blade snapper.
10:00The people that first came up with this brilliant invention were engineers,
10:04inspired by the way chocolate bars are segmented.
10:07Hold on a minute, don't throw away the cardboard package just yet.
10:10Most likely, you'll have some silica gel packets somewhere at the bottom of the box.
10:14Since this gel is basically a drawing tool,
10:17it gathers up the moisture out of its environment,
10:19so you can store these packets for further occasions.
10:22Whether you'll need to dry out your phone or some other electrical object,
10:26you can place them in a container next to the silica gel to reduce the damage.
10:31You don't have to be a mechanic to know when a standard car tire needs replacing,
10:35since they come equipped with a neat indicator.
10:37Take a closer look,
10:39and you'll see that treads within the tire are a bunch of rubber notches.
10:43When the treads are evened out with the perpendicular bars,
10:46it's a sign you need to book an appointment with your local car service,
10:50since most likely the tires have lost most of their traction
10:53and may not be safe for driving any longer.
10:56The upper corners of a car windshield feature textured black dots
11:00melted into the glass edges.
11:02This neat add-on isn't there for design purposes.
11:05It's called Frit Glazing,
11:07which means that a special type of ceramic paint
11:10is added to the window for protecting its sealant from UV rays.
11:14It also conceals and creates a coarser surface
11:18for the adhesive used to set the window in place.
11:21Whenever you're up for a drive,
11:23check out if there's a small tab under your car's rearview mirror.
11:28Bet you didn't know it's there to help switch the mirror
11:30from daytime to nighttime views.
11:33It uses a prismatic glass technology to blur the reflection
11:37and reduce the glare of headlights behind you in traffic.
11:41People came up with these manually tilted mirrors in the 1930s,
11:45but they became standard somewhere in the 1970s.
11:48While you're in the car,
11:50check out the headrests,
11:51as you most likely don't know
11:52that they carry a little disguised purpose.
11:55Of course, they're adjustable to accommodate passengers
11:58of any height so that they get the proper support
12:00for their heads and necks.
12:02The hidden feature is that they are detachable
12:04and come with two very solid metal bars.
12:08Should you ever find yourself stuck in a car
12:10and need to make a fast getaway?
12:12These bars come in handy to crack out the car windows.
12:15So you're out for a drive and you're suddenly out of gas.
12:19What I'm about to describe sounds more like a meme
12:21than an actual situation bound to happen.
12:24But what if you're in such a hurry
12:26that you accidentally drive off with the gas nozzle still in the tank?
12:30Well, the nozzles have been designed to prevent any hazards from happening, rest assured.
12:35They feature a breakaway device that will allow the hose to separate
12:39when taken out with enough force.
12:41Initially designed in the early 20th century
12:44to be worn exclusively by basketball players,
12:47sneakers soon became one of those fashion fundamentals
12:50similar to jeans and leather jackets.
12:52If you take a closer look at them,
12:54you'll see they have two extra holes on the side,
12:56similar to the shoelace holes.
12:58They're manufactured as such
13:00not only to provide extra ventilation,
13:02but to allow people to get extra creative with their laces
13:05when wearing the shoes.
13:07Admit it, you've always thought that chopsticks are merged at the end
13:10for the sole purpose of keeping them together
13:12until you're ready to dig into your meal.
13:14That may or may not be the whole truth.
13:17Under a more detailed inspection,
13:19the wooden tools feature a square-shaped end.
13:22Chopsticks manufactured like this
13:24date back to an old Japanese traditional design,
13:27which can help with breaking the ends easily.
13:29The separated end can then be used as a resting block for the chopsticks
13:34to keep it more sanitized in hopes it can be used again,
13:37since they won't be touching the table or any other surface.
13:41Women's bikes have a special design,
13:43which, surprisingly, has a historical and fashionable purpose.
13:47The lower frame is for the most part
13:49meant to make up for the generally shorter height of ladies,
13:52compared to that of the average gentleman.
13:54While that is the case for handlebars and saddles,
13:57the overall frame is lower for an additional purpose.
14:00Way back when women wore long skirts and dresses all day,
14:04every day they needed to make sure their outfits
14:06wouldn't get caught in the frame.
14:08That's how we came up with a lower-framed bicycle,
14:11perfectly made for women and their needs at the time.
14:15The fact that toothpastes are multicolored
14:18is not just a nice perk to make dental hygiene more fun.
14:21There's a secret meaning related to each of the colors,
14:23which dates back to the 1970s.
14:26In those days, people grew more and more interested
14:29in their oral health care,
14:31and as such, they were looking for products
14:34which could do more than merely clean their teeth.
14:36One company was the pioneer in that regard,
14:39adding mouthwash to its toothpaste,
14:41meaning the blue strip.
14:43They later added on the red strip,
14:45meant to feature ingredients which helped with gum care.
14:49Speaking of toothpaste,
14:50check the cap next time you open a new tube.
14:52You may be in for a little surprise.
14:54There's a pointed cone shape inside the cap,
14:57so you can puncture the seal of the toothpaste
14:59without cutting yourself or ruining your manicure.
15:02Not to mention, it's more hygienic
15:04since you won't be able to transfer germs
15:06or other bacteria into the product itself.
15:10On the subject of bathroom countertop items,
15:13toothbrushes come with a neat add-on
15:15hidden in the bristle patterns.
15:16Apart from making the toothbrush look cooler,
15:19they also do come with a practical purpose.
15:22Most toothbrushes come with a pattern of blue bristles
15:25intertwined with white ones.
15:26The blue dye is meant to fade out,
15:29signaling the time when you need to replace your toothbrush.
15:32Dentists say that toothbrushes should be replaced
15:34every three to four months,
15:36but it does serve as a great reminder in case you forget.
15:39Still love playing with Lego?
15:41Don't judge.
15:42Hey, it's a great hobby for all ages.
15:45Notice there's a hole on top of the Lego heads?
15:47Behold, you're looking at a safety feature
15:49that the people at Lego designed to prevent choking hazards.
15:53The most dangerous issue should a person swallow
15:56any of these pieces is the blocking of the airways.
15:59Designing a hole inside the Lego head
16:02helps the air to flow freely through the piece
16:04until it can be removed safely.
16:07We're now used to all sorts of modern light bulbs,
16:10some tubular, some shaped like diamonds,
16:12and some even twisted all together.
16:15Historically, light bulbs were round
16:17and the initial shape served a purpose in itself.
16:20It was mainly connected to the fact
16:22that glass bulbs were hand-blown,
16:24which gave them the round shape to begin with.
16:27The hidden practical reason
16:28was that the light bulb filament
16:30needed to be at the same distance
16:31from every surface of the glass sphere.
16:34The easiest way to achieve this
16:35was to make the glass in the shape of a globe.
16:40You just spent the entire morning
16:42running errands up and down the street,
16:44and you finally stopped to treat yourself
16:46to a cup of coffee.
16:47You enter the nearest coffee shop,
16:50place your order,
16:50and notice that actually,
16:52you really need to use the bathroom.
16:54It's a regular-looking public one
16:56with multiple stalls.
16:58As you pick yours, the one in the middle,
17:00you get inside,
17:01and your mind starts to wander.
17:03Why on earth do bathroom doors
17:05have a half-inch gap
17:06between the door and the lock?
17:08And why on earth do they have a huge gap
17:10between the door and the floor?
17:12Can we have a drumroll for this moment, please?
17:15Well, my friend,
17:16there is not only one specific reason
17:18why public bathroom doors
17:20have so many gaps in them,
17:22but rather several.
17:23Public toilets are designed
17:25to make people spend
17:26as little time there as possible.
17:28You aren't supposed to feel comfortable
17:29or at home.
17:31So the design would have to reflect
17:33this notion.
17:33Here come the gaps.
17:35In some bathrooms,
17:37gaps are so big
17:38that users may even feel self-conscious
17:41about doing their business
17:42out of preoccupation
17:43that the rest of the people
17:44standing in line will see them.
17:47Then there's the matter of pricing.
17:49Making custom doors
17:50can be a heavy burden
17:51for the people building public toilets.
17:53This would mean understanding
17:55exact measurements
17:56so that doors would always fit
17:58the mold of the stalls
17:59it's supposed to be installed into.
18:01Now, not all the gaps
18:03in public bathrooms
18:04are necessarily the same size.
18:06They may vary,
18:07even if this variation is small
18:09and often unnoticeable.
18:11So these gaps actually help
18:13to reduce the margins of errors
18:14and to turn production
18:16more cost-effective
18:17for the people financing them.
18:19In case a door comes wider
18:21or more narrow than it should,
18:23the gap regulates the differences
18:24and allows for their installation anyway.
18:27There is also the case
18:29of air circulation.
18:30The last thing you want to do
18:32in a public bathroom
18:33is to trap odors.
18:34So you need a little space
18:36under and between the doors
18:37to allow the air to flow.
18:40Finally, the gaps are a big safety measure.
18:42It can always allow for people
18:44on the outside
18:44to see if someone inside a stall
18:47isn't feeling too okay
18:48and maybe need some help.
18:50And what about that extra hole
18:52in the upper part of the sink?
18:54It has a name in everything.
18:55The overflow hole.
18:57And it's designed
18:58to keep the sink from flooding.
19:00So in case someone forgets
19:02and keeps the faucet going for too long
19:04or the sink gets clogged
19:05and water can't drain down
19:07from the main drain hole,
19:08the overflow hole comes in
19:10to save the day.
19:12Let's say it buys you a little time
19:13before you have
19:14the entire bathroom floor flooded.
19:16Have you ever noticed
19:17how satisfying closing
19:19the door of a car can be?
19:21Car manufacturers devote
19:22a great deal of time
19:23to designing these sounds.
19:25Studies have shown
19:26that they create
19:27a perceived sense of quality
19:28in the buyer.
19:29It all begins
19:30with the primary material.
19:32While older cars
19:33used to be made
19:34with heavier materials,
19:35car doors nowadays
19:36are produced with lighter tin,
19:38which can make
19:39a rather unpleasant metallic sound
19:41once you shut them closed.
19:43So car companies
19:44employ sound engineers
19:45to ensure that there is
19:47the exact amount of foam,
19:48mats, and tin
19:49in a car's composition
19:51to make the most comforting
19:52sound possible.
19:54And what about
19:55those tiny dots
19:56on the top
19:56of your car's front window?
19:58The pattern
19:59of these little black dots
20:00minimizes distractions
20:01for your eyes.
20:02This black part,
20:04also known as frit,
20:05normally gets warmer
20:06than the clear parts,
20:07which prevents
20:08the windshield
20:09from deforming.
20:10And no,
20:11the tab under
20:12your rearview mirror
20:13is not made only
20:14for the purpose
20:15of hanging fluffy dice
20:16or aromatic-pleasing
20:17air fresheners.
20:18It's actually a switch
20:20that allows you
20:20to adjust the position
20:21of the mirror
20:22depending on the time of day.
20:24Flip it one way
20:25and it's the daytime driving mode.
20:27Flip the other
20:28and you're ready
20:29to drive safely
20:30during nighttime
20:30as it tones down
20:31the glare
20:32coming from headlights
20:33of the cars behind you.
20:35Next time you head out
20:36to the supermarket,
20:37make sure to keep this in mind.
20:39In case you don't have a coin
20:40to unlock these shopping carts,
20:42there is a well-kept secret
20:44that can help you out.
20:45If you have your house keys on you,
20:47check for a rounded key head.
20:49If you happen to find one,
20:51try using it
20:51to unlock the cart.
20:53It should fit perfectly in there,
20:55replacing the need
20:56to carry coins around.
20:57Because,
20:58if we're being honest,
20:59who still has them?
21:01Elevators.
21:01If you want to ride them
21:02on your terms
21:03and your terms only,
21:04make sure to try something out.
21:06Most elevators
21:07have a secret button combination
21:09you can use
21:10to skip all the other
21:11selected floors
21:12and go directly
21:13to the one
21:13of your choosing.
21:14This might work out,
21:16especially on those days
21:17when you've pressed 13.
21:18But you wanted to press 33.
21:21On most elevators,
21:22this works
21:23once you simultaneously
21:24press the closed door button
21:25together with your floor number.
21:27This should help you
21:28get to your floor
21:29without stopping.
21:30Some elevators require you
21:32to double-press
21:33the selected floor numbers,
21:34as double-pressing
21:36will often cancel
21:37the previously made request.
21:38While other elevators
21:40require you
21:40to hold the open door button
21:42and then double-press
21:43the buttons of the floors
21:45you'd like to cancel.
21:46Now,
21:47to stay out of trouble,
21:48it's best not to cancel
21:49the floors
21:49of the other people
21:50in the elevator.
21:51They won't take it kindly.
21:53Also,
21:54keep in mind
21:54that there are elevators
21:55that might not have
21:56this function.
21:57Now,
21:58for honey lovers out there,
21:59go ahead and raise your hand.
22:01If your pot of golden honey
22:02is crystallized,
22:04know that it is actually
22:05a good sign.
22:07Crystallized honey
22:07means that it hasn't
22:09been pasteurized,
22:10which means
22:10better product quality.
22:12With a decrease in temperature,
22:14the natural ingredient
22:15of honey,
22:16also known as glucose,
22:17will make it crystallize.
22:19Now,
22:19try making the best of it.
22:21To add some texture
22:22to your oatmeal or toast,
22:23add a layer of crystallized honey
22:25and enjoy nature's sugar.
22:27And if you don't like
22:28crystallized honey,
22:29plop it in the microwave
22:30for a minute or two.
22:32Ah,
22:33winter and fall.
22:34You know what this means,
22:35right?
22:36Sweater weather.
22:37But there's nothing
22:38more annoying
22:38than wearing your
22:39beautiful wool sweater
22:41and itching yourself
22:42all the way through it.
22:44Actually,
22:44I can be more annoying
22:45than that,
22:46but let's talk about
22:47itchy sweaters.
22:48To keep this from happening again,
22:50here's the secret.
22:51Turn your sweater
22:52inside out
22:53and soak it in cold water.
22:54Add two or three
22:55tablespoons of vinegar
22:57and let it sit for a while.
22:58Then,
22:59drain the water.
23:00Now,
23:01while the sweater
23:01is still wet,
23:02massage a generous amount
23:04of hair conditioner
23:05into the fibers
23:06of the wool.
23:07After letting it soak
23:08in the hair conditioner
23:09for about 30 minutes,
23:11gently press the excess water
23:12out of the wool
23:13and leave it to dry flat
23:15on a towel.
23:16There you go!
23:17No more itchy sweater.
23:19Any fast food restaurant
23:20you go to
23:21will hand out
23:22small paper cups
23:23for customers to fill
23:24with their ketchup,
23:25mustard,
23:25or barbecue sauce.
23:27But if you're eating
23:28some chicken nuggets
23:29or trying to dip
23:30your burger into the cup,
23:31there's always that bit of sauce
23:33that seems impossible to reach.
23:35Next time,
23:36try unfolding the cup.
23:38It'll turn into
23:39a small paper plate,
23:40and this way,
23:41you'll get all the ketchup
23:42you poured in the first place.
23:45Padlocks used
23:46in outdoor environments
23:47should be clean
23:48and lubricated
23:49every three months.
23:50Regular lubrication
23:52will help prevent padlocks
23:53from freezing
23:54in cold weather conditions.
23:55Look for the tiny hole
23:57on the bottom of the lock,
23:58then pour oil into it,
24:00and there you go!
24:01It opens again!
24:03One thing we often neglect
24:05is a point in an ointment cap.
24:07These pointy surfaces
24:08were designed to help us
24:09break the tinfoil protection
24:11of the ointment tube.
24:12You just turn the cap over
24:14and break the ointment seal
24:16with its own cap,
24:17and there you go!
24:19After a long day of work,
24:20all you really need to do
24:22is a bubble bath.
24:23You turn on the hot water
24:24and let it run for a few minutes.
24:26You might even light a candle
24:28and pour some essential oils
24:29into the water.
24:30Then, in comes the liquid soap.
24:33You stir the water
24:34until the entire surface
24:36of the tub water
24:36is crammed with bubbles
24:38and make your way in.
24:40The bubbles in a bubble bath
24:41have a fundamental
24:42primary function.
24:43Their job is to preserve
24:45the water's temperature,
24:46just so you can have
24:47warm water for longer.
24:49Do you have sweaty feet?
24:51Weird question, I know.
24:52But if you're one of these people,
24:54here's some good news.
24:56All is not lost.
24:57Try putting a dry tea bag
24:59inside your shoes
25:00and storing it
25:01in a dry place for a while.
25:03The tea bags will absorb
25:04the humidity and the smell
25:06off the soles of your shoes.
25:08So, here I am thinking,
25:10shouldn't we have learned
25:11these things in school?
25:12Well, either way,
25:13if you learned something new today,
25:15make sure to tell us about it
25:16in the comments below.
25:25Have a good look at the front
25:27of your sweatshirt.
25:27Okay, let's ignore
25:28the pizza stains for now.
25:30Ever notice that V-shape
25:31right at the bottom
25:32of the collar?
25:33That small V-patch
25:34isn't just a decoration,
25:35it serves more than one purpose.
25:37Made from a double layer
25:39of webbing material,
25:40just like waistbands and cuffs,
25:41these inserts allowed the wearer
25:43to put on the sweater
25:44without losing any shape over time.
25:46As the sweatshirt
25:47would be pulled down
25:48over the head,
25:49the V-insert would stretch
25:51and flex to allow
25:52a lot of wiggle room.
25:53The other benefit
25:54the V-pattern gives
25:55is to absorb all that sweat.
25:57The chest is a major area
25:59of perspiring.
26:00Just look at soaked shirts
26:01after doing something physical.
26:03Although, the V-insert
26:04can only take so much.
26:07That extra pocket
26:08on the right side
26:09of a suit jacket
26:09is called the ticket pocket.
26:11They used to store coins
26:12for people on horseback
26:14to pay tollbooths
26:15without opening their jackets.
26:16When train travel
26:17became more popular,
26:19they were perfect
26:19for tickets and passes.
26:21As for the left chest pocket,
26:23it's used to store handkerchiefs,
26:24keeping them away
26:25from the other cluttered
26:27and dirty pockets.
26:28Metallic zippers
26:29have a hidden lock built in.
26:30Next time you've put on
26:32a pair of pants,
26:33shorts, or skirt,
26:34never leave the zipper handle
26:35in an upward position.
26:37Push the little zipper tab downwards,
26:39and it'll automatically lock.
26:40To mute your annoying beeping microwave,
26:43look closely at the front panel
26:45for a sound button.
26:46It may have been there all along,
26:48just begging to be pressed.
26:49If there's no button,
26:51try pressing and holding
26:521, 0, stop, or cancel.
26:54It will either result
26:55in turning off the beeping sounds
26:57or activating a lock feature.
26:59Of course,
27:00if your microwave
27:00doesn't have any mute function at all,
27:03you'll just have to keep running
27:04to stop the timer late at night.
27:06Nintendo Switch cartridges
27:07have a hidden safety function,
27:09and it's going to leave
27:10a bad taste in your mouth.
27:12Although non-toxic,
27:13denotonium benzoate
27:15coats the cartridge
27:16in a sour, peppery,
27:17and bitter substance
27:18to prevent kiddos
27:19from swallowing them.
27:20This chemical compound
27:21is one of the most bitter flavors
27:23known to humanity,
27:24commonly used to keep people
27:26from consuming things
27:27they're not meant to.
27:28There's not much privacy
27:29while using a public toilet,
27:31especially when the door
27:32doesn't reach the floor at all.
27:34But these gaps are there
27:35for emergency access,
27:36in case the person inside
27:38needs immediate help.
27:39The gap also works
27:41for ventilation,
27:42thank goodness,
27:42and to stop people
27:43from lingering around
27:44the toilet too long.
27:46Toothpicks have a built-in holder
27:48to prevent you
27:48from just leaving them
27:49on the table.
27:50Just break off the top,
27:52it's that simple.
27:53Place that on your table
27:54and your toothpick
27:55between the notches,
27:56pointy end up, of course.
27:58Now, it won't touch the table
27:59and get all dirty.
28:00You can do the same
28:01with disposable chopsticks.
28:03Break off the top piece
28:04before you pull them apart.
28:06Those tiny dimples
28:07on golf balls
28:08actually give a greater lift
28:09to the ball
28:10and reduce air resistance,
28:12meaning the ball
28:12can go further with them.
28:14These dimples come in spherical
28:15and hexagonal shapes
28:17with each slightest change
28:19affecting the ball's performance.
28:20So, choose them carefully.
28:23Plastic wrap boxes
28:24have hidden little holders
28:25that stop the roll
28:26from jumping out of the box.
28:28They're little cardboard tabs
28:29on the sides
28:30that lock into the tube inside
28:32while making it easy
28:33to glide the film out.
28:35Just push them in
28:36and never be frustrated again.
28:38Gosh, I wish that would work
28:39with other stuff.
28:40The seven spikes
28:42on top of the Statue of Liberty's crown
28:44don't represent the seven seas
28:45and the seven continents at all.
28:47They're representing the sun's rays,
28:50giving a halo
28:50to show that she is divine.
28:53In the United States,
28:5412 different Federal Reserve Banks
28:56print all the money.
28:57So, if you want to know
28:58where your money comes from,
29:00just look for these small codes.
29:02A1, Boston.
29:03B2, New York.
29:05C3, Philadelphia.
29:06D4, Cleveland.
29:08E5, Richmond.
29:09F6, Atlanta.
29:11G7, Chicago.
29:12H8, St. Louis.
29:14I9, Minneapolis.
29:16J10, Kansas City.
29:18K11, Big D, Little A, Double L A S.
29:21It's a song.
29:22L12, San Francisco.
29:24Never call it Frisco.
29:26Meanwhile,
29:27the bristles on the side
29:28of every escalator
29:29are in place
29:30to encourage people
29:31to stay away from the edge,
29:32meaning they're less likely
29:34to face a mishap
29:35with a trapped bag or shoelace.
29:37Did you hear about
29:38the octopus caught on the escalator?
29:39It was a stretch.
29:41Old-fashioned pin cushions
29:42that are large tomato
29:43with a strawberry attached
29:45are more than a place
29:46for your needles.
29:47The strawberry contains
29:48an emery board.
29:50When you stick your pins
29:51and needles into the strawberry,
29:52the emery board
29:53keeps them rust-free
29:54and sharpens them as well.
29:56Some people still forget
29:58to engage the hose
29:59from their car
29:59after filling up with gas.
30:01Luckily,
30:02a lot of gas companies
30:03realize this,
30:03so if you happen to drive off
30:05with a hose
30:06still attached to your car,
30:07there's a magnetic connector
30:09that disengages when pulled.
30:11Those different colored bread tags
30:13use a color-coded system
30:14to show the day
30:15that they were baked.
30:16They are usually
30:17blue tags for Mondays,
30:18green tags for Tuesdays,
30:20red tags Thursdays,
30:22white tags Fridays,
30:23and yellow tags for Saturdays.
30:25On the back
30:26of most beauty products,
30:27you'll find a small symbol
30:28on the back
30:29that indicates
30:30how long it'll stay good for.
30:32For example,
30:332M means
30:34two months after opening.
30:36Some jackets
30:36have those extra flaps
30:38with a button on the shoulder,
30:39and they actually
30:40have a use.
30:41These are perfectly designed
30:42for holding your purse,
30:44backpack,
30:44or bag in place
30:45and secure.
30:46Pom-poms
30:47on the top of beanies
30:48were never just
30:49a fashion statement.
30:50They were for protection,
30:52placed on top
30:53of the headwear
30:53to protect sailors
30:54from accidentally
30:55hitting their heads
30:56while moving around
30:57on a ship.
30:58Pom-poms touch the roof,
31:00so don't go any higher.
31:01They don't appear
31:02on every type
31:03of measuring tape,
31:04but diamonds
31:05or black circles
31:06are there to help
31:07contractors measure
31:08the proper placement
31:09of studs in a wall.
31:11Those little holes
31:12on your baseball cap
31:13aren't some fashion trends
31:15that stuck around for years
31:16and have never been changed.
31:18These holes
31:18are actually called eyelets,
31:20and they're to keep
31:21your head well-ventilated,
31:22not for appearance.
31:24If you have YKK
31:25printed on your zipper,
31:27they're not some secret
31:28code to be cracked.
31:29Those three letters
31:30appear on so many
31:31zippers globally
31:32because they're the symbol
31:33of the world's
31:34most universal
31:35zipper manufacturer,
31:36the YKK Group.
31:38Every can of soda
31:39comes with a tab
31:40for easy opening
31:41of the tasty beverage,
31:42and every single one
31:43of them has a relatively
31:45large hole in the top.
31:46While it can make it easier
31:48to get your finger
31:49under the tab
31:49to get your soda,
31:50its intended purpose
31:52is a straw holder.
31:53Spin the tab
31:54over the opening
31:55and place your straw
31:56through it
31:56to secure it in.
31:58Disposable lids
31:59do a great job
32:00of keeping your drink
32:01inside the cup,
32:02but that's not
32:02its only purpose.
32:03When you're ready
32:04to sip on your drink,
32:05the lid has
32:06specially designed ridges
32:07to double it as a coaster
32:09and hold onto the bottom
32:10of your beverage tightly.
32:12The tiny black dot
32:13between the lens
32:14and the flash
32:15on the back of your iPhone
32:16is actually
32:17for a great purpose.
32:18It's the third microphone
32:20to provide superior
32:21sound quality
32:22by eliminating
32:22background noises
32:23and to pick up your voice
32:25much clearer
32:25in a crowded environment.
32:27Gas cans
32:28that have two holes
32:29with caps
32:30aren't there
32:31to fill different-sized
32:32equipment.
32:33The second hole
32:33is meant to be uncapped
32:35before you pour your gas
32:37to prevent that
32:37glugging effect.
32:38By allowing more airflow
32:40through,
32:40the smoother the gas
32:41will pour out.
32:43That little arrow
32:44next to the gas symbol
32:45on your car's dashboard
32:46shows you which side
32:48your gas tank is on.
32:49It'll help you
32:50when you go fill up
32:51your gas tank,
32:52especially if you're
32:53borrowing a different car
32:54than your own.
32:55Look at a check
32:56and see MP
32:58near the signature line.
32:59That means the check printer
33:00used microprint
33:02as one of the check
33:03security features.
33:04The lines look like
33:05a regular line
33:06to the untrained eye,
33:07but they're words
33:08like the bank's name,
33:09authorized signature,
33:11United States government,
33:12or even
33:12original document.
33:13That little disc
33:15that's underneath bottles
33:16isn't just a leftover
33:18part of the production process.
33:19It creates an even
33:21tighter seal with the lid,
33:22so even if the bottle
33:24was turned upside down,
33:25the liquid doesn't
33:26leak out everywhere.
33:27The plastic disc
33:28keeps carbonated sodas
33:30carbonated for longer
33:31with this seal.
33:32The indent
33:33in the bottom
33:34of wine bottles
33:34is called a punt,
33:36but it's not just something
33:37to help you hold
33:38onto the bottle.
33:39The punt
33:39makes the wine bottle
33:40stronger,
33:41so if dropped,
33:42the cork won't fly
33:43across the room
33:44with all that pressure.
