00:00You're trying on a pair of jeans, a dress, or a jacket, and are about to dig your hand into
00:05the pocket when you realize there's no depth to it.
00:08The pocket is simply not there.
00:11But why would anyone create pockets you can't put anything in?
00:15And now would be a good time to pick your iPhone up from off the floor.
00:19Well, the reason for fake pockets is simple.
00:22If a clothing item has a specific cut or shape, pockets may spoil it.
00:27They can alter the item's shape, either in the warehouse or already on the retail rack.
00:32The solution? Getting rid of pockets in key areas.
00:36Plus, fake pockets are obviously cheaper, and they don't get stretched out.
00:41Interestingly, this practice goes back to the 17th century.
00:44That's when pockets were actually removable.
00:47They resembled small bags, and women, for example, could move them from one outfit to another.
00:53Unfortunately, it was also very convenient for pickpockets.
00:57They could grab such a pocket and run off with it.
01:00Then clothes became more streamlined, and slim pockets started to be sewn right into them instead of attachable bags.
01:08This was believed to make the shape of a person's silhouette more alluring.
01:12But soon, slimmer skirts came into fashion, and pockets went out of it.
01:17And people started using handbags instead.
01:20These days, most pockets are real.
01:23But some of them are still fake.
01:25So, how can we make sure that we don't actually turn a fake pocket into a hole, thinking it's a
01:31real one?
01:31Well, first of all, take a look at the stitching along the edge of the pocket, where it's supposed to
01:36open up.
01:37If you see a single loose thread, just snip a piece of it and start pulling gently.
01:42If the pocket is real, the thread will easily come out.
01:46But if you feel that the stitching won't budge, most likely, you have a faux pocket on your hands.
01:52If this is the case, just leave it be.
01:56Now, let's move on to some other everyday objects that may be hiding some secrets.
02:01For example, those lines on some kinds of chips.
02:04For one thing, they help with the distribution of spices and seasonings.
02:08In other words, all those substances that make your chips taste like cheese are mostly stored inside the lines.
02:15Plus, the lines make chips crunchier.
02:19Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.
02:25Yellow and light green hues are the most popular because they don't prevent you from seeing the text after black
02:31and white photocopying.
02:33Photocopiers perceive yellow and light green marks as almost non-existent and don't print them.
02:39Now, back in the day, the first jeans had one problem.
02:43Workers and miners, who were the original jeans wearers, put too much pressure on the poor piece of clothing.
02:49As a result, the seams couldn't withstand the stress and tore.
02:53So, tiny metal studs were invented to prevent this from happening.
02:58Most metallic zippers have a hidden lock inside them.
03:01That's why you shouldn't leave the zipper handle in an upward position.
03:05When you pull it downwards, it automatically locks.
03:08It's all thanks to several tiny grooves hidden underneath the handle.
03:13Now, about those horizontal lines on plastic bottles.
03:16They help hold bottles up.
03:18Some bottles are produced from soft plastic.
03:21Without the lines, they wouldn't keep their shape.
03:24Instead, they would twist easily or even break.
03:27Bath foam isn't only for fun or a nice smell.
03:30It helps regulate the temperature, too.
03:32The bubbles keep the water hot, and you can enjoy your bath a bit longer.
03:37With or without your rubber ducky.
03:40Ever notice that layer of clear liquid in gel pens?
03:44It's called the ink follower or stopper fluid.
03:47The gel in such pens contains pigment particles dissolved in a polymer solution.
03:52The gel should be thick enough to keep the pigment particles suspended,
03:56but also thin enough to flow first onto the ball and then the paper.
04:00The main task of the stopper fluid is to be a barrier to prevent the gel from evaporating or leaking
04:07out.
04:08Without this transparent fluid, your gel pen wouldn't function.
04:11The fluid always stays in one position and doesn't get dissolved with the gel.
04:16Neither does it move backward or flow out of the pen.
04:19The holes in the bottoms of your earphones allow air to circulate up and through the speakers.
04:25It allows to increase low frequencies, making the bass sound deeper.
04:30The quality of the sound also becomes much better.
04:33Some plastic milk containers have dents on their sides.
04:36Try as they might, they just cannot park without some damage.
04:41Nah, I made that up.
04:42These dents serve several purposes.
04:44For one thing, when milk spoils, this process usually causes swelling and high-pressure buildup inside the container.
04:51Oh boy!
04:52That's when the dent comes in handy.
04:54It pops out and doesn't let the jug blow up.
04:57Plus, if you ever decide to freeze the milk, it will expand like any other liquid.
05:02And then again, the indentation will pop out and prevent the container from breaking inside your freezer.
05:08That's a good thing.
05:10Airplane windows have rounded edges, and that's a crucial safety measure.
05:15It prevents aircraft accidents.
05:17Weak spots are usually situated in the corners.
05:20If airplane windows were square or rectangular, each of them would have four potential weak spots.
05:26Under pressure, they would collapse.
05:29If you look closely at a tram's overhead lines,
05:32you'll see that its contact wires zigzag back and forth instead of going in a straight line.
05:38The thing is that all trams have pantographs attached to their roofs.
05:42The upper part of the pantograph is gradually worn down by the overhead wire and eventually needs to be replaced.
05:49To wear it down evenly, the wire is not installed strictly along the tram's path, but in zigzag patterns.
05:56As the tram moves, the pantograph slides along the wire and it wears down evenly.
06:02You might have wondered why some gas cans have two holes with caps, one bigger and one smaller.
06:09Before, I thought that the little hole was used when you poured something into a smaller container.
06:13But I was wrong.
06:15A very infrequent occasion.
06:17In reality, you're supposed to uncap it before you pour the gas inside the bigger hole
06:22to prevent it from glugging and spilling on your clothes and on the ground.
06:27Most of the buttonholes on a shirt are vertical, but the top and sometimes bottom ones are horizontal.
06:34The reason is simple.
06:35These two buttons slip out more often than others.
06:38Luckily, producers have found the solution that can prevent these buttons from slipping out.
06:43Horizontal buttonholes.
06:45What engineering!
06:46Buttons tend to slip out less from such buttonholes.
06:50Sticks sachets of sugar or salt are easier to open than many people think.
06:54There's no need to tear off one of the ends.
06:57The right way is actually to tear them down the middle.
07:01Some boots have loops sticking out on the back.
07:04Their main purpose is to help you pull your shoes on easier.
07:07Just tug on the loop while you're pushing your heel into the boot.
07:10You can also use these loops to hang your boots on a hook when they're dirty or when you want
07:16to dry them after washing.
07:17Or you can run your laces through the loop if you want to tie them around your ankle.
07:22When you're on board the plane, you might spot a little triangle over your seat.
07:27Such triangles show the flight crew the best spots to check the plane's flaps through the window, just in case
07:33they're flapping.
07:34If your shoes are really slippery, just take a bit of sandpaper and rub it on the soles for better
07:40traction.
07:41They'll become more grippy, and you'll be able to wear them out in the rain.
07:45Now, if they get too wet, they might turn griping, but that's only if you have talking shoes.
07:51If you drill several holes at the bottom of your garbage can, putting in and taking out trash bags will
07:57become much easier.
07:58You won't have any problems with suction.
08:01You can usually find some silica gel in bags, shoes, and many other things you buy.
08:07This shell absorbs excess moisture.
08:09Don't throw it away.
08:10Each time your shoes get wet, put a few packets of silica gel inside.
08:16The thermos wasn't actually invented to keep your coffee warm.
08:20It was made by a Scottish scientist who just wanted a safe place to put his chemicals at a stable
08:25temperature.
08:26So, he took two bottles, put the smaller one inside the bigger one, and vacuumed out the air between them.
08:33Well, anyway, thanks for the hot coffee!
08:38Whether it's something as simple as a button on your jeans, or something that's part of a larger moving mechanism,
08:44here are 26 secrets to everyday things you probably didn't know about.
08:50You use doorknobs every day, so it's right to be concerned about how many germs could be on them.
08:56However, they have made doorknobs out of brass partly for that reason.
09:01Brass provides an antimicrobial effect, eliminating the microorganisms that were hoping to start a colony on your doorknob.
09:09Your pants have that one-fifth pocket that's recognized as the small, useless one.
09:14Originally, it was there to provide a safe place for your pocket watch,
09:18something that was necessary when first implemented in 1901.
09:22It then continued to remain for traditional purposes.
09:25However, it's still a great place to put your Tic Tacs.
09:29You've probably mistaken those little rivets on your jeans as some form of fashion statement,
09:34similar to the small pocket.
09:36In fact, they're incredibly important.
09:39They are there to provide extra support for areas that withstand the most strenuous parts of your clothing,
09:45preventing them from embarrassingly falling apart.
09:48That little button at the end of your seatbelt seems like it's way out of place.
09:53In fact, it's there to ensure your buckle will always remain at the end,
09:57so you won't have to awkwardly fiddle with your seatbelt every time you put it on.
10:02You're in a new car or a rental,
10:04and the gauge tells you the gas is getting low.
10:07You don't know which side the fuel cap is on from the inside.
10:10It can cause unnecessary effort at the gas station.
10:14However, your fuel gauge has an arrow that reminds you which side to fill your gas tank up from.
10:20Some models of cars may also have a gas tank hose instead,
10:24with the hose pictured on the side that the cap is on.
10:28Hiking and walking through snow requires the best kind of footwear.
10:33The shoes which are perfect for this also have an extra eyelet for your lace to loop through.
10:38Looping your laces through the extra eyelets will give more support for your ankles and feet,
10:43and will provide more stability as you walk.
10:46But as you walk, blisters are also a concern.
10:50The sweat in your shoe creates friction between the feet and the shoe,
10:55which then helps create the blisters.
10:58Antiperspirant that you use for your armpits will help keep the feet from sweating.
11:02Just make sure you use the clear one.
11:05Cooking for people is always nice.
11:08However, sometimes the guests are late.
11:11Yep, we're all guilty of that sometimes, right?
11:14The extra drawer under your oven, where you've been keeping all of your spare pots and pans,
11:20was actually made to keep your food warm.
11:22Great for those who are late to the meal.
11:25Ever wondered how long that padlock could possibly last when it's outside,
11:29in the rainy weather, keeping your bike safe?
11:32It has a little hole at the bottom of it.
11:35It's there to drain water to avoid corrosion on the inside.
11:39It also serves to provide oil, further prolonging its use.
11:44That hole in the elevator door isn't there to check who's inside,
11:48so you can avoid sharing a ride with specific people.
11:51It's a keyhole, in case it breaks down.
11:55Ketchup, sauce bottles, and all other condiments we love
11:58all have a stage when it's difficult to get the insides out.
12:02You try hitting it, shaking it,
12:04and poking things inside to encourage the tasty condiments to come out.
12:08Luckily, there is an easier way to do it.
12:12The label at the top suggests where to tap the bottle.
12:16The sauce will come out easier and smoother,
12:19allowing gravity to take the place of frustration.
12:23The purpose of wooden coat hangers is to help repel pesky insects
12:27and avoid fungal growth that eats away at your clothing,
12:30as it's made of cedar wood.
12:33It contains oils that have insecticidal and fungicidal properties
12:37and were used as far back as the ancient Egyptians,
12:41although they used it for other purposes.
12:45We've all been trained and tested at the art of typing
12:48and know the correct way to use a keyboard.
12:51But you may not have noticed that the F and J keys
12:54have a small ridge at the bottom.
12:56They're there to help you find your correct starting place
13:00with your fingers on the keyboard,
13:01without having to look down.
13:04If you've been lucky enough to get the window seat on the plane,
13:07you would have noticed that little hole at the bottom of the window.
13:11It helps with the air pressure on the plane.
13:13The window itself is made from acrylic and isn't actually glass,
13:18which saves it from fogging up so you can see the scenery on your journey.
13:22The windows on planes were originally square.
13:25However, they would continuously break from the constant changes in pressure.
13:30Round windows are able to evenly distribute the pressure,
13:33ensuring you'll have a pleasant journey without falling out.
13:36For all you Nintendo Switch players,
13:39those who have tried to taste your cartridges
13:41will notice they have a bitter taste.
13:43The manufacturers added it intentionally,
13:46as the Switch's cartridge size is very small,
13:49and it might be a hazard for the youngest players
13:52that have a tendency to put things in their mouth that they shouldn't.
13:56So, the bitter taste made from denotonium benzoate ensures that they won't be tasted for too long.
14:02Cosmetics containers that are filled with products used for your skin
14:06have a secret number on them.
14:09This is to help inform you how long the product will be usable,
14:13ensuring it doesn't cause the reverse effect by damaging your skin instead.
14:19Pen lids have a hole at the end of them.
14:22It's not there to help your pen breathe and boost performance,
14:25but it's there to help you breathe.
14:27Just in case while you're sitting in class or at work
14:30and you're chewing on your lid and just happen to swallow it,
14:33you can be rest assured if it's stuck,
14:36the pen makers were thinking of you.
14:39When you're traveling by car or any other form of ground transportation
14:43and you're trying to drink your favorite pop from a straw,
14:46you'll find it quite difficult to do at times.
14:49Simply turn the tab on the can around so that your straw easily fits inside,
14:54making it easier to drink out of.
14:57There are always spare buttons when buying new clothes,
15:00along with a little bit of fabric.
15:02It's far too small to repair that crutch part that always rips first.
15:06The fabric is actually there for you to test how to wash it,
15:09so you don't accidentally ruin your brand new clothes.
15:14Determining how much pasta you need just for yourself can be difficult to figure out.
15:18Your big spaghetti spoon with the big hole on the inside,
15:21that looks like it's there to drain water,
15:24is actually there so you can put the uncooked pasta inside before cooking,
15:28so you know exactly how much you need.
15:32New shoes always come with those strange little packets,
15:36that silica gel.
15:37The gels are there to reduce the moisture in the air
15:40to avoid any fungal growth while the shoes were waiting to be purchased.
15:44There's a lot of chemistry involved to get you that silica,
15:48and it's very effective, capable of absorbing 50% of the humidity.
15:53So make sure you don't throw it away.
15:55Next time you need to dry out your electrical devices,
15:58it's a lot easier than using rice.
16:01It's difficult enough to see at night whilst driving,
16:04but it's even worse when the driver behind you shines their high beams.
16:08Your rearview mirror has a tab at the bottom.
16:11When you press it, it changes the angle.
16:14One is for day driving, the other, well, for nighttime.
16:17It'll help in case that one person driving behind you
16:20has forgotten to turn off their high beams.
16:23Although your screwdriver is ergonomically made for your hand,
16:26sometimes you have that one screw that's too hard to loosen up.
16:30The handle is also shaped so you can easily fit inside of a ring spanner or wrench,
16:36allowing you to apply more force,
16:38ensuring that you can remove that troublesome screw.
16:41The skirt part on an escalator seems like a good spot to get your foot stuck.
16:46But in reality, those long brushes poking out
16:48aren't there to give you an extra shine on your shoes,
16:51but for safety precautions,
16:53to minimize the risk of trapping objects
16:55between the steps and the side of the escalator.
16:59Many shirts have two buttons on the cuffs,
17:02but only one buttonhole.
17:04So what is the second button for?
17:07Turns out you can use it whenever you're wearing a watch,
17:10so the cuff is looser.
17:13Most clothing items you buy come with a small bag of fabric
17:16or a button, or both.
17:19Buttons obviously can be used as a replacement
17:21if you lose the original ones.
17:23Pieces of fabric can be used to patch up a hole,
17:26but most importantly, it's a tester.
17:29You can use it to test different washing products on it
17:32and see what happens to the fabric.
17:35Some umbrellas have a tip at the top,
17:38and it turns out it's not just a pretty design.
17:41When going inside on a rainy day,
17:44you should just close your umbrella
17:45and tap the tip against the floor
17:47to drain the water faster and more effectively.
17:51Many backpacks have this diamond
17:54with two parallel cutout slits on its front,
17:56and it's there for your comfort.
17:59You can attach something to it,
18:01like a water bottle or shoes.
18:03It comes especially handy if you travel somewhere
18:06or go hiking,
18:07so you don't have to hold your stuff.
18:10Okay, the next thing is gear loops,
18:13and probably from the name of it,
18:15you already have an idea what they're there for.
18:17You can strap in some useful gear
18:19you need to have with you,
18:21like trekking poles or shovels.
18:23Some gear will need to be secured to do it.
18:26Drop the handle through the loop
18:27and rotate it upward.
18:29Then, secure it with the elastic hook at the top,
18:32and you're golden.
18:34On the back of many makeup and hygiene products,
18:38you can find this symbol with a marking,
18:40like 6M, 12M, and 24M.
18:44This is the number of months
18:46this product can serve after you open it
18:49and before you should throw it out.
18:52The two sides of a cotton pad are different
18:55because each of them has a particular purpose.
18:58A cotton pad has several layers
19:00to ensure that it's soft,
19:01strong,
19:02and can absorb liquids.
19:04The edge is stitched to hold it all together.
19:08The smooth side of a pad is for applying products,
19:11like tonics and lotions.
19:12And the embossed side is best for cleansing
19:15and makeup removal.
19:18Also, any pack of cotton pads
19:20has those strings on the sides.
19:22They're there so you can hang the package somewhere.
19:25Then, you can open the package at the bottom,
19:28where the perforated line is,
19:29and take them out.
19:32Did you know that there is an efficient
19:34way to pull a thread from yarn?
19:36When you pull from the outside,
19:38the yarn rolls away,
19:39so you need to hold it.
19:40However, if you pull it from the center,
19:42it will stay together.
19:45We're all familiar with staplers,
19:47but I bet you don't know all its secrets.
19:51Most staplers have a compartment
19:52to store spare staples,
19:54which can be located either on top
19:56or at the bottom.
19:58Also, surprise!
20:00This metal plate you press staples against
20:02can be turned around.
20:04This way, the device will be able
20:06to staple your documents
20:07by turning the metal ends outwards.
20:11No need to wonder whether you need
20:12to get a smaller or bigger container.
20:15Turns out, plastic food containers
20:17have volume measurements on their bottoms,
20:19indicating how much food they can fit.
20:23Ceiling fans come with a small switch
20:25on the inside of the blade.
20:26You might not have noticed it
20:28because it's not in plain sight,
20:29so check yours out.
20:31This switch allows you to change
20:33the direction of rotation.
20:35Now, why would you want to do that?
20:38The blades of a fan push the air
20:40in different directions,
20:41depending on the way they rotate.
20:43In the summer,
20:44you need the air to be pushed down
20:47to create the effect of a breeze.
20:49In the winter,
20:50the direction should be changed
20:52so that the air is pushed
20:53towards the ceiling.
20:55It then heats up
20:56before going down the walls.
20:59Have you noticed
21:00that the gas tank sign
21:02on car's dashboards
21:03has a little arrow next to it?
21:06Well, this arrow has a purpose.
21:08It points at the side of the car
21:10where the gas tank is located.
21:12It's very useful
21:13for forgetful people
21:14who constantly wonder
21:16where the gas tank is
21:17and also for those
21:18who drive rentals
21:19once in a while.
21:20The answer is right
21:21in front of your eyes.
21:23If you can't find the arrow
21:25on your panel,
21:25then the fuel hose
21:27on the icon
21:27indicates the side instead.
21:31All car tires
21:32have 12-digit numbers
21:34printed on them
21:35and they're actually
21:36important codes
21:36for car owners
21:37if they want to get
21:38the right tire.
21:40The first letter
21:41identifies the type of tire.
21:43P stands for a tire
21:45for light passenger cars
21:47and LT is for heavy vehicles.
21:50Then, the following numbers
21:51stand for the width
21:53of the tire,
21:53its radial,
21:54and its diameter.
21:57Measuring tapes
21:58have that metal stud
21:59on the end
22:00which you can use
22:01to attach the tape
22:02to the surface you measure.
22:04This way,
22:04you don't need
22:05to hold it yourself.
22:07But there's also
22:08a small slot
22:09which can be used
22:10to hang the tape
22:11on a nail,
22:12again,
22:12to free your hands
22:13and keep measuring.
22:15The bottom of the end
22:17of the tape
22:17has a ridged edge.
22:19It will help you
22:20make a mark
22:21if you don't have
22:21a marking tool with you.
22:24On the tape,
22:25there are black diamonds
22:26that are placed
22:27every 19.2 inches.
22:29They're useful
22:30for construction workers
22:31when spacing
22:32engineering joists.
22:34They can also be useful
22:36for you
22:36if you want to hang
22:37something heavy,
22:38for example.
22:39The diamond will mark
22:40the exact center
22:41of a wooden joist.
22:43Those are placed
22:4416 inches apart
22:45from one another.
22:46There,
22:47you can drill something
22:48to that center
22:49to make sure
22:50whatever you hang
22:51is safely attached
22:52to the joist
22:52instead of the unreliable
22:54thin wall.
22:55Pictures will survive,
22:57but it's particularly
22:58important
22:58if you're hanging
22:59something heavy.
23:01Did you know
23:02that batteries
23:03have an expiration date?
23:05Yes,
23:06it's printed
23:07right on their label,
23:08but I've never
23:09noticed it before.
23:10The expiration date
23:12doesn't mean
23:12you can't use it
23:13after that.
23:14It's more like
23:16a recommended usage period,
23:18after which
23:18the manufacturer
23:20can't guarantee
23:21full battery life
23:22due to
23:23deteriorated components.
23:26These little feet
23:28keyboards have
23:29are actually
23:30a standard.
23:31The height
23:32of a keyboard
23:33should be adjustable,
23:34allowing the angle
23:35between 0 degrees
23:37and 15 degrees.
23:39The reason
23:40to fold the feet
23:41out
23:41is for you
23:42to see the keys
23:43better,
23:44in case you don't
23:45type blindly.
23:46A little problem
23:47that comes with it
23:48is that,
23:49in this case,
23:50your wrists are bent,
23:52and it's not good
23:53to keep them
23:54in this position
23:55for a long time.
23:58Pans have those holes
23:59on the ends
24:00of their handles.
24:01They're not just there
24:02for you to hang them.
24:03You can also place
24:05your cooking spoon
24:06in there.
24:07It'll hang
24:08right above the pan,
24:09and the sauce
24:10will not spill around.
24:12Make sure to tap off
24:14the sauce or food
24:15beforehand, though,
24:16so that it doesn't
24:17go down the spoon's handle.
24:21Stickers with numbers
24:22you can find on fruits
24:23can tell you
24:24some information
24:25on how the food
24:27was grown.
24:28A four-digit code
24:30that starts with a four
24:31means that the fruit
24:33was grown conventionally,
24:35meaning it contains
24:37chemicals and pesticides.
24:39So your best choice
24:40should be a fruit
24:41with a five-digit number.
24:43And if you see
24:45the number nine,
24:46it indicates that
24:47the fruit
24:47is certified organic.
24:50On the bottom
24:52of plastic bottles,
24:53you can often notice
24:54a mark of a triangle
24:56with a number
24:57engraved in the middle.
24:58This number specifies
25:01the type of plastic
25:02that was used
25:03to produce the bottle.
25:05These codes help people
25:07and local recycling centers
25:09to sort returns.
25:11Products that were made
25:12of plastic of types
25:14one and two
25:15are the easiest ones
25:17to recycle.
25:18Plastics of types
25:20three through seven
25:21are tougher to recycle.
25:25If you look at it
25:26on the street,
25:27you'll think a fire hydrant
25:28is about three feet
25:29in height.
25:30But the actual size
25:31of the device
25:31used to provide water supply
25:33to firefighters
25:33all over the world
25:34is twice as large.
25:36That is,
25:37if you count the rest
25:38of the hydrant,
25:38which is hiding underground.
25:40They're mostly red
25:41and it's not just a matter
25:42of urban design.
25:43First of all,
25:44they need to be of bright,
25:45easily noticeable colors
25:46so firefighters can spot them
25:48fast when they need to.
25:49The choice of color
25:51depends on how much water
25:52the hydrant can hold.
25:53It can sometimes vary
25:55depending on the location,
25:56but here's the breakdown.
25:57A red fire hydrant
25:58can splash 500 gallons
26:00of water per minute,
26:02while an orange one
26:03at least 1,000 gallons.
26:06Green ones mostly process
26:081,500 gallons of water
26:09per minute,
26:10and the most plentiful ones
26:11colored blue
26:12can generally contain
26:13over 1,500 gallons.
26:16Hey bowling fans,
26:17isn't it super annoying
26:18when your bowling ball
26:19gets cracked?
26:20Turns out that most of them
26:21get damaged
26:22because of incorrect storage
26:23or spikes in temperature.
26:26Now come on and face it,
26:28since it's already cracked a bit,
26:29aren't you curious
26:30what's actually inside
26:31the bowling ball?
26:32Because I sure am.
26:33Let's have a look.
26:34They mostly make
26:35the inner core of the ball
26:36of powdered metal oxides,
26:38like calcium
26:39or iron oxide.
26:40They mix them
26:41with some resin
26:42and catalyst
26:42to harden the whole mixture.
26:44So that light bulb shape
26:46you now see inside of the ball
26:47is actually its heaviest part.
26:49It also influences
26:50how your bowling ball rotates
26:51when going down the lane.
26:54The same goes
26:55with spray paint cans.
26:56When you shake it,
26:57it makes a weird noise.
26:59But what is that thing in there?
27:00It's called a pea,
27:02and it's meant to hold
27:03the paint mixture in place
27:04and maintain its shape.
27:05They generally make it
27:07out of plastic,
27:07metal,
27:08or ceramic.
27:09It basically acts
27:10as a whisk
27:11to make sure your paint
27:12is well mixed together
27:13before you apply it
27:14to your surface of choice.
27:16Ever wondered
27:17how soda bottles
27:17keep that refreshing fizz
27:19for that long?
27:20Well,
27:21they have a little plastic ring
27:22fastened to the lid.
27:23They place it there
27:24to keep the gas
27:25from escaping
27:26and making the soda
27:27go flat,
27:27even if you shake it around
27:29in your bag
27:30the whole day.
27:32Speaking of things
27:33we use on a hot summer's day,
27:34wait, wait,
27:35don't put your baseball cap
27:36on just yet.
27:37Take a look at it
27:38for a minute,
27:39and you'll notice
27:39there's a small button
27:40on the very top.
27:41Is it functional
27:43or is it just there
27:43for the sake of design?
27:45Way back when people
27:46started using fabrics
27:47to cover their heads,
27:48some say the button
27:49was actually functional.
27:51Since it's on top
27:52of the cap
27:52where the fabric panels
27:53come together,
27:55the top button
27:55helps keep the cap crown
27:56in one single piece.
27:58Now,
27:59with recent advances
28:00in fabric
28:00and pattern design,
28:02the button is more
28:02of an aesthetic feature.
28:04It's used to cover up
28:05the joint point
28:05of the fabric panels.
28:07Your cap might not
28:08have a button at all,
28:09but don't you think
28:10a cap actually looks better
28:11with one?
28:13Cotton pads
28:13have two sides,
28:15and if you take the time
28:16to look at them carefully,
28:17they're actually
28:17different in texture.
28:19Just in case
28:20you've ever wondered why,
28:21the textured side
28:22is for applying makeup,
28:23and the even side
28:24is for removing it.
28:27Bookworms,
28:28this one is for you.
28:29Dust jackets
28:30that come with a lot
28:31of hardcover books
28:31are not just meant
28:32to make your book
28:33look pretty,
28:34they also double
28:35as a bookmark.
28:36Just fold the pages
28:37you've already read
28:38underneath the inside
28:39of the jacket,
28:40and voila!
28:41Next time you reach out
28:43for your favorite shirt,
28:44take a look at the top
28:45buttonhole.
28:45It should be stitched
28:46horizontally,
28:47and all the other ones
28:48are vertical.
28:50Turns out that the dress
28:51shirt was designed
28:52this way,
28:52since the first
28:53and the last buttons
28:54were the first ones
28:55to unbutton
28:56throughout the day.
28:57They then changed
28:58the direction
28:59of the buttonhole
28:59to ensure the shirt
29:00would stay nice
29:01and fitted
29:02before you're ready
29:02to take it off.
29:05These days,
29:06we have so many variations
29:07of this awesome dessert
29:08that it's hard to imagine
29:09we've ever lived
29:10without it.
29:11You can find
29:11different types
29:12of cookie dough ice cream
29:13or even chocolate chip
29:14cookie cake
29:15basically everywhere,
29:16but the famous cookie
29:17wasn't actually invented
29:19until 1930.
29:20The story goes
29:21that a woman named
29:22Ruth Graves Wakefield
29:23was preparing
29:24some chocolate cookies
29:25as she was waiting
29:26for some guests
29:27to arrive.
29:27She soon figured out
29:29she was out of
29:29Baker's chocolate,
29:30a crucial ingredient
29:31for the classic cookies.
29:33To fix things up,
29:34she chopped up
29:35a block of
29:35semi-sweet chocolate
29:36thinking it would
29:37eventually spread out
29:38evenly throughout
29:39the batter
29:39given the heat
29:40of the oven.
29:41Things didn't necessarily
29:42go as planned,
29:43but hey,
29:44it's great they didn't
29:45because this is how
29:46she invented
29:46this modern dessert
29:47we now can't
29:48get enough of.
29:50And speaking of
29:51popular snacks,
29:52the potato chip
29:53is even younger
29:54than the chocolate chip
29:55cookie.
29:56Well,
29:56at least historically.
29:58There are many stories
29:59trying to explain
30:00how it was invented
30:01one of them
30:02goes like this.
30:03A chef named
30:04George Crumb
30:05based in New York
30:06put the chips together
30:07in 1953.
30:09He decided to try
30:10a different cooking
30:11solution when one
30:12of his customers
30:12didn't have nice
30:13things to say
30:14about his french fries.
30:16He said they were
30:16too thick
30:17and kind of mushy.
30:19Then,
30:19Crumb came up
30:20with potatoes
30:20that were thinly
30:21sliced and fried
30:22until brown.
30:23People absolutely
30:25loved the dish
30:26and they welcomed
30:27the first ever
30:28batch of chips
30:28with open arms.
30:31Ice cream anyone?
30:32If the story is true,
30:33back in 1904
30:35at the St. Louis
30:36World's Fair,
30:36one ice cream shop
30:37owner ran out of cups
30:39to serve his dish.
30:40So,
30:40he fashioned a waffle
30:41into the shape
30:42of a cone
30:43and the rest was history.
30:45Okay,
30:46I'll admit it,
30:47chewing gum-like treats
30:48have been around
30:49since the ancient Greeks.
30:50So this one
30:51isn't particularly
30:52a revolutionary discovery.
30:53But the actual gum
30:54we buy today
30:55wasn't there
30:56until the late 1800s.
30:58An American inventor
31:00named Thomas Adams
31:01wanted to mix together
31:02different chemicals
31:03to create rubber.
31:04He tried and failed
31:05for that matter
31:06to play with Chickle
31:07for his experiment
31:08but ended up
31:09fashioning this neat treat.
31:11They still use Chickle
31:12to this day
31:12to produce most chewing gums.
31:15Back in the 1800s,
31:16there lived a man
31:17named Jean-Baptiste Jolie
31:18who worked in the fabric industry
31:20as a textile maker.
31:22How he came up
31:23with this next invention
31:24that we use a lot
31:25these days
31:25has less to do with him
31:26and more to do
31:27with his maid.
31:29The story goes
31:30that the woman
31:31accidentally knocked
31:32a kerosene lamp over
31:33onto a tablecloth.
31:35Instead of getting upset
31:36over the damaged fabric,
31:38Jolie noticed
31:39that the substance
31:39actually made
31:40the material cleaner.
31:41Figured it out yet?
31:43Yep,
31:43that's how the idea
31:44for the very first
31:45dry cleaner popped up.
31:46A very neat accident
31:48if I do say so myself.
31:51Now this one I loved.
31:52Did you know
31:53matchsticks
31:54were initially called
31:55friction lights?
31:56Or at least
31:57that's how their inventor,
31:58a chemist named
31:59John Walker,
31:59called them back in 1826.
32:02He scraped a stick
32:04coated in chemicals
32:05across his hearth
32:06totally by accident
32:07one day
32:07and realized
32:08that they ignited
32:09and created a spark.
32:11Initially made out
32:12of cardboard,
32:13they were then made
32:14using wooden splints
32:15and sandpaper.
32:18Back in the 1940s,
32:19a man named Harry Coover
32:21stumbled upon
32:21a chemical formulation
32:22that seemed to stick
32:23to everything it touched.
32:25The scientific community
32:27at the time
32:27didn't look much into it
32:28as the formula
32:29didn't seem to have
32:30many applications back then.
32:32It wasn't until 1951
32:34that he looked a bit more
32:35into the formula
32:36and decided to repurpose it.
32:38Along with a fellow
32:39Eastman Kodak researcher
32:41named Fred Joyner,
32:42they gave it a proper full name.
32:44But you must know it
32:45by the shorter version,
32:47Super Glue.
32:49It also has many uses
32:51in security these days
32:52that it's hard to believe
32:53that we didn't come up
32:54with this one on purpose.
32:56Back in 1903,
32:57a scientist
32:58named Edward Benedictus
33:00knocked over a flask
33:01by accident.
33:02He looked down
33:03and was amazed to see
33:04that the glassware
33:05had just slightly cracked
33:07but maintained its shape.
33:08He was expecting it
33:09to break into
33:10a million tiny pieces.
33:12Curious about this
33:13hidden feature,
33:14he looked into it
33:14and figured out
33:15what was keeping
33:16the glass together
33:17was a substance
33:18coating the inside
33:19of the glass.
33:20Ta-da!
33:20That's how humanity
33:22came up with safety glass.
33:25Various types of cheese
33:27have holes for a reason.
33:29For example,
33:30Swiss cheese is made
33:31with special bacteria
33:32that produce carbon dioxide.
33:34As the CO2 is emitted,
33:36it blows like bubble gum,
33:38leaving tiny craters,
33:39also known as cheese eyes.
33:41Then the cheese is cooled down,
33:43but the holes stay in place.
33:47Over 40 billion Oreos
33:49are made every single year.
33:51It's the world's most popular
33:53manufactured cookie.
33:54The geometric design
33:56stamped onto these cookies
33:57has the Nabisco logo,
33:59the symbol of European quality,
34:01surrounding the word Oreo.
34:03William Tournier
34:04created the chocolate cookie design
34:06we see today
34:07back in 1952.
34:11If you use reusable bottles,
34:13you probably know
34:14that sometimes they smell.
34:16Even if you only use it
34:18for regular water,
34:19it still smells.
34:20But it's not the water
34:22that smells,
34:22it's the microorganisms in it.
34:25If you drink water
34:26from a bottle,
34:27the particles of your saliva
34:28and sweat stay in there.
34:30Those bacteria start to build up
34:32in the bottle,
34:32causing the smell.
34:34So, if you choose
34:35reusable bottles,
34:36make sure to wash them
34:38every day
34:38to prevent those bacteria
34:40from building up.
34:41After washing,
34:42let it dry completely
34:43before using it again.
34:47Not only are the jeans blue,
34:49but the police officers'
34:51uniforms as well.
34:52The first official police officers
34:54appeared in the 19th century
34:55in London.
34:56They were given
34:57a blue uniform
34:58to contrast
34:59with the red and white uniform
35:00that military workers
35:02had already been wearing.
35:03Two decades afterward,
35:05the police force
35:06was adopted in the USA,
35:07and they followed the patterns.
35:09The uniform is still blue nowadays
35:11because it proved
35:12to be a good color.
35:13It's not that visible
35:14in dark hours,
35:15and police officers
35:17can observe things
35:18and people
35:18staying unnoticed.
35:20Also, stains aren't that visible
35:22on dark material.
35:23And, well,
35:25everyone knows
35:25that police officers
35:26wear blue
35:27and they're recognized in.
35:29So, why change that?
35:32Baby carrots are tiny,
35:34and unlike regular carrots,
35:36wet.
35:37Not unlike baby humans.
35:39Baby carrots
35:39aren't some special
35:41sort of carrot.
35:41They're actually
35:42made of regular carrots
35:44by cutting off the skin
35:45and outer layers
35:46and then polishing them
35:47to look that pretty.
35:49The problem is,
35:50they can't retain moisture.
35:51A regular carrot
35:52retains some water inside
35:54because of the layers
35:55that lock it in.
35:56Once they're chopped out,
35:58baby carrots
35:58can dry out easily.
36:00So, they usually
36:01sell them in bags
36:02with some water inside.
36:06Jeans have metal rivets
36:08and they're there
36:08from the very beginning.
36:10Jacob Davis,
36:11the man who made
36:12the first pair of jeans,
36:13added copper rivets
36:14to spots where pants
36:16are more likely to rip,
36:17flies in pockets,
36:18to make them stronger.
36:20Today, they have more
36:21of a decorative purpose
36:22since they are distinctive
36:23and traditional for jeans.
36:25Another special thing
36:27about jeans
36:27is those tiny pockets
36:29they have
36:29that seemingly
36:30served no purpose.
36:32Well, maybe it's true now.
36:34But years ago,
36:35when many cowboys
36:36were wearing jeans,
36:37the pocket was made
36:38specifically
36:39to keep a pocket watch there.
36:41Also, back then,
36:42a pair of jeans
36:43had just four pockets.
36:45That tiny pocket,
36:46the watch pocket,
36:47two big pockets in front,
36:49and just one pocket
36:50in the back.
36:53Car headrests
36:54are all about comfort
36:55and detachable headrests
36:56are all about safety.
36:58If you pull the headrest out,
36:59you'll see two sturdy
37:01metal bars.
37:02If you ever get locked
37:03or trapped in a car,
37:04you can use the bars
37:05to smash the window
37:06and get out.
37:09Those little red spots
37:11you sometimes see
37:12after you crack an egg
37:13are nothing to be worried about.
37:16Tiny blood spots
37:16can be caused
37:17by a small rupture
37:18in a blood vessel
37:19of a hen
37:20as it was laying the egg.
37:22Eggs with these blood spots
37:23are safe to eat,
37:24but that spot
37:25can be removed
37:26if you want.
37:27It won't affect
37:28the taste of the egg.
37:29Oh, that's comforting.
37:32Hidden within
37:32the Toblerone logo
37:34of the mountain
37:34is the image
37:35of a bear
37:36standing on its hind legs
37:38about to eat
37:38that yodeler over there.
37:40No, not really.
37:41This is because
37:42bears are a big part
37:43of Bern,
37:44one of the biggest cities
37:45in Switzerland
37:46where the founder
37:47created the triangular
37:48chocolate tree.
37:49Toblerone is also
37:50a play on the founder's
37:52family name,
37:53Tobler,
37:53and the Italian word
37:55Torone
37:55for honey and almond nougat.
38:00The space below
38:01a cup of noodles
38:02is there to protect
38:03the noodles
38:03during transport.
38:04This technique
38:05is called
38:05a middle suspension.
38:07Not only are they
38:08protected better
38:09in their styrofoam cup,
38:10but it also helps
38:12those noodles
38:12soften more evenly
38:13and quickly.
38:14Even though you
38:15might have noticed
38:16that the hole
38:17on the barrel
38:17of ballpoint pens
38:18has no purpose,
38:20it does.
38:21It's called
38:21a venting system,
38:22which helps the ink
38:23flow more smoothly.
38:24This way,
38:26an even amount
38:26of air pressure
38:27is created inside
38:28and outside the pen,
38:30allowing the ink
38:31to flow into the point
38:32easily.
38:34It's not an accident
38:35that soy sauce bottles
38:36have two spouts.
38:38The sauce is liquid
38:39and it flows out
38:40of the bottle
38:40pretty quickly
38:41once you turn it over.
38:42Most Asian food lovers
38:44will admit
38:44they've spilled it
38:45at least once
38:46in a lifetime.
38:47That's why,
38:48nowadays,
38:49restaurants prefer
38:50serving soy sauce
38:51in special bottles
38:52that have two spouts.
38:53This design allows
38:55you to control
38:55when and how much
38:56sauce will come out.
38:58Just put your finger
38:59on one spout
39:00while you pour
39:00the sauce through another.
39:02If you press your finger
39:03tightly to the spout,
39:04the sauce will stop flowing
39:06and if you remove
39:07your finger,
39:08it will flow again.
39:09And please,
39:10do not remove
39:11your finger
39:11in a restaurant.
39:12It will freak
39:13everybody out.
39:15You've probably noticed
39:17that train and bus seats
39:18are covered in fabrics
39:19with weird patterns.
39:21Any idea why?
39:22They use these patterns
39:23to cover any germs
39:25and stains on the seat.
39:26Oh boy.
39:27The brighter the color
39:28and the more patterned it is,
39:30the harder it will be
39:31for a passenger
39:32to notice any stains
39:33and get grossed out.
39:34Also,
39:35the patterns are usually
39:36so ugly
39:37that no one even
39:38wants to look at them
39:39for long enough
39:40to spot any stains.
39:41So yeah,
39:42the pattern is there
39:43to make you look away
39:44and if you look,
39:46to make it less noticeable.
39:47No bus will ever
39:49have plain white seats.
39:50That's a guarantee.
39:53The middle tab
39:54on soda cans
39:55can be flipped around.
39:56You can slip a straw
39:57in place
39:57so you don't have
39:58to hold it up your mouth.
40:00This stay-on tab
40:01replaced the pull ring tab
40:02created in the early 60s.
40:04You remember those,
40:05don't you?
40:06Those could be
40:06quite sharp
40:07and easily discarded
40:08where they could be
40:09a menace for others.
40:10Now,
40:11you can pop your straw
40:12straight into one.
40:13Also means
40:14you can produce
40:15some bubbles
40:15and make a mess
40:16like a three-year-old.
40:19Sometimes,
40:19when you purchase
40:20an article of clothing,
40:21you receive
40:22a plastic baggie
40:23with an extra button
40:25and a swatch of fabric.
40:26While the fabric
40:27is clearly used
40:28to patch holes,
40:29it can also be used
40:31to test the effects
40:31of various cleaners
40:33on certain surfaces.
40:34It's handy, too,
40:35to test wash cycles
40:36before using them
40:37to wash the whole garment.
40:41Escalators have
40:42those fluffy black brushes
40:43for a similar reason
40:44that some have
40:45yellow lines
40:46on their steps
40:47to try and deter people
40:49from getting too close
40:50to dangerous places.
40:51People don't always
40:53take notice,
40:53and sometimes,
40:54clothing can drape
40:55close to the point
40:56where the step
40:57meets the edge
40:58or skirt.
40:59The brush
41:00is a little barrier
41:01to help prevent
41:01this from happening.
41:02They can also
41:03catch bits of fluff
41:04and prevent other
41:05small things
41:06from falling down
41:07into the gaps.
41:09Those takeaway containers
41:11most associated
41:12with Chinese restaurants
41:13are designed
41:14to not only
41:15carry your food home,
41:16but to store it
41:17in the fridge.
41:18They double as a plate
41:20as you can eat
41:20straight out of them
41:21and don't have to worry
41:22about dirty dishes.
41:24Yay!
41:24They were actually
41:25patented way back
41:26in 1894
41:28to transport
41:29freshly shucked oysters
41:30and were known
41:31as oyster pails.
41:32They were later
41:33adapted to use
41:34as leak-proof containers
41:35for food.
41:38Ever wondered
41:39why coins
41:39have those little ridges
41:41along the edge?
41:41It's a leftover
41:42from earlier times
41:43when they were worth more.
41:45Counterfeiters
41:46could easily
41:46file the edges off
41:48to sell as gold
41:49or silver coins
41:50to make some profit.
41:51The ridges
41:52were created
41:52so it was much easier
41:54to tell which of the coins
41:55had been altered.
41:56It's not needed today,
41:57but the coins
41:58still have that altered style.
42:02All crackers
42:03and some cookies
42:04have holes
42:05to make sure
42:05the final product
42:06has the right texture.
42:08These teeny tiny holes
42:09allow steam to escape
42:10so your crackers
42:12and cookies
42:12won't snap.
42:13If it weren't
42:14for these holes,
42:15also known as dockers,
42:17steam would build up
42:18inside the tree
42:19and the final result
42:20might have been scrumptious
42:21but it would have been
42:22rather oddly shaped.
42:25Dogs like to walk
42:26in circles
42:27before snoozing
42:28because they inherited
42:29this behavior pattern
42:30from their ancestors.
42:32There were no special
42:33doggy beds back then
42:34so most pooches
42:35would have to push down
42:36tall grass
42:37to make a sort of
42:38snoozing spot.
42:39Plus, as a bonus,
42:41those movements
42:42scared off all the critters
42:43lurking in the vegetation.
42:46Donuts are ring-shaped
42:47for a similar reason.
42:49If they hadn't had holes
42:50right in the center,
42:51the dough there
42:52would have always
42:53been undercooked.
42:54By the way,
42:55they're often associated
42:56with the police
42:57because back in the 1950s,
42:59doughnut shops
43:00were among the only places
43:01openly.
43:02They were a perfect place
43:04for police officers
43:05to grab something to eat
43:06and even deal with
43:07some paperwork
43:08during the night shift.
43:11Your jeans are blue
43:12on the outside
43:12and white on the inside
43:14because of a smart way
43:16to weave the fabric.
43:17The warp thread is dyed
43:19while the weft thread
43:20has no color.
43:21It's just white.
43:23This way,
43:23manufacturers reduce
43:24the amount of dye
43:25needed for each piece
43:27of clothing.
43:28And they're still dying
43:29to make the jeans.
43:34You know,
43:35there are all sorts
43:36of amazing things
43:37you can do with products
43:38already lying around the house
43:40that were meant
43:41for other things.
43:43We'll explore some of those,
43:44plus everyday items
43:46that have other purposes
43:47you may not be aware of.
43:49I'm also in a silly mood,
43:51so hey,
43:51let's have some fun.
43:53Many pairs of kitchen scissors
43:55today have a serrated opening
43:57where the handles
43:58and blades meet.
43:59You can use this
44:00as an herb stripper
44:01to de-stem difficult herbs
44:03like thyme,
44:04rosemary,
44:05and chives.
44:06Saves you a lot of time
44:08trying to pick
44:08the leaves off by hand.
44:10And if you're short
44:11of a vase,
44:12you could present roses
44:13to your significant other
44:14this way.
44:15Just be careful
44:16when you're pointing
44:17the sharp end.
44:19The metal tab
44:20on soda cans
44:21can be flipped around.
44:22You can slip a straw in place
44:24so you don't have to
44:25hold it up to your mouth.
44:27This stay-on tab
44:28replaced the pull ring tab
44:29created in the early 60s.
44:31You remember those,
44:33don't you?
44:33Those could be quite sharp
44:35and easily discarded
44:36where they could be
44:37a menace for others.
44:39Now,
44:40you can pop your straw
44:41straight into one.
44:42Also means
44:43you can produce some bubbles
44:44and make a mess.
44:47Sometimes,
44:48when you purchase
44:48an article of clothing,
44:49you receive a plastic baggie
44:51with an extra button
44:52and a swash of fabric.
44:54While the fabric
44:55is clearly used
44:56to patch holes,
44:57it can also be used
44:59to test the effects
45:00of various cleaners
45:01on certain surfaces.
45:02It's handy, too,
45:03to test wash cycles
45:05before using them
45:06to wash the whole garment.
45:08And,
45:09if you want to clean
45:09your nose with it,
45:11that suggestion
45:11never came from me.
45:14You can use a screwdriver
45:15for leverage
45:16if you're having trouble
45:17lifting or moving something.
45:19Some also have
45:20a hexagonal-shaped handle
45:22that fits inside
45:23a wrench or spanner.
45:24You can use it
45:25to improve torque
45:26and, again,
45:27for leverage.
45:28A little easier
45:29on your hands.
45:30Some of us
45:31aren't that strong.
45:32Or,
45:32maybe that's just me.
45:35Rubber bands
45:35are great for many things,
45:37but if you have a bottle
45:38that's hard to open,
45:39you can wrap the band
45:41around it
45:41for a better grip.
45:44Escalators
45:45have those fluffy
45:46black brushes
45:47for a similar reason
45:48that some have
45:49yellow lines
45:49on their steps.
45:51To try and deter people
45:52from getting too close
45:53to dangerous places.
45:55People don't always
45:56take notice,
45:56and sometimes,
45:57clothing can drape
45:59close to a point
45:59where the step
46:00meets the edge
46:01or skirt.
46:02The brush
46:03is a little barrier
46:04to help prevent
46:05this from happening.
46:06They can also
46:07catch bits of fluff
46:08and prevent
46:09other small things
46:10from falling down
46:11into the gaps.
46:13Your average pair
46:14of jeans
46:15has several features
46:16that are both
46:17functional
46:17and somewhat sentimental.
46:19The metal rivets
46:21around the pockets
46:22help secure
46:22the stress points.
46:23This ensures
46:24they last a bit
46:25longer than average,
46:27though not all
46:28jeans have them.
46:29Many still have
46:30a tiny pocket
46:32directly above
46:33the main pocket.
46:34This was originally
46:35meant to hold
46:36a pocket watch.
46:37Even though pocket watches
46:38are mostly a thing
46:39of the past,
46:40many people still
46:41use this space
46:42to store coins,
46:44rings,
46:44or even a portable USB.
46:47Now,
46:48this may seem
46:49a little obvious,
46:50but if you've ever
46:51wondered what all
46:52the notches are
46:53in a car tire,
46:54it's for traction
46:55on the road.
46:56However,
46:57there are also
46:57a good indicator
46:59if your tire
46:59is getting too
47:00worn down.
47:01If those notches
47:03aren't so deep anymore
47:04and are almost
47:05flush with the road,
47:06it's time
47:07to replace them.
47:08If you don't,
47:09the next time
47:10you try to stop
47:11suddenly at a stop sign,
47:12you might be surprised
47:14to find your car
47:15has turned
47:15into a giant
47:16roller skate.
47:18Those takeaway containers
47:19most associated
47:21with Chinese restaurants
47:22are designed
47:23to not only
47:24carry your food home,
47:25but to store them
47:26in the fridge.
47:28They double as a plate
47:29as you can eat
47:30straight out of them
47:31and don't have to worry
47:32about dirty dishes.
47:34Yay!
47:34They were actually
47:36patented
47:36way back in 1894
47:38to transport
47:39freshly shucked oysters

47:43They were later adapted
47:44to use as leak-proof
47:46containers for food.
47:48While you're sitting
47:49on an airplane
47:50and looking out
47:51the window,
47:52you may have noticed
47:53those little holes
47:54or, in some instances,
47:55a small singular opening
47:57near the bottom.
47:58This is called
47:59a breather hole
48:00and, no,
48:01it's not for you.
48:02It's designed
48:03to equalize
48:04the difference
48:04in air pressure
48:05which builds up
48:06between the pressurized cabin
48:08and the atmosphere
48:09outside,
48:10especially during
48:11high altitudes.
48:12It also releases
48:14moisture from
48:14between the panes
48:16to avoid frost
48:17from forming
48:17on the windows
48:18and obstructing
48:19that all-important view.
48:21Sorry,
48:22but it looks like
48:22you won't be drawing
48:23a smiley face
48:24on it anytime soon.
48:26This was first introduced
48:28way back in 1956
48:30by a company in Japan.
48:32Pretty cool, huh?
48:33They got their inspiration
48:34from snap-off rows
48:36on chocolate bars.
48:37Just don't get
48:38the two mixed up.
48:39One doesn't taste good.
48:42When it comes
48:43to measuring tape,
48:44almost every reel
48:45has an empty slot
48:46in the metallic end.
48:48This is called
48:49a nail grab,
48:50so you can attach it
48:51to a nail or screw.
48:53A handy trick
48:54to do measurements
48:55without requiring
48:56someone else
48:57to hold it in place.
48:58Ooh, very nifty.
49:01Bobby pins have grooves
49:03on one side
49:04to hold your hair
49:04in place better.
49:06Crazy notion, huh?
49:07The straight side
49:08goes face up
49:09while the grooves
49:10go down against your head.
49:12They're called
49:13bobby pins
49:14because of the bobbed
49:15hairstyle
49:15which was popular
49:17in the 1920s,
49:18though the pins
49:19were invented
49:20in the 19th century.
49:21The look is gone,
49:23but the pins remain.
49:24Please take them out
49:25before you wash your hair
49:27as they don't look great
49:28stuck to your fingers.
49:30If you've been in a car
49:32or a bus
49:32and noticed
49:33the textured black dots
49:35baked into the black edges,
49:37you've probably worked out
49:38that it's not there
49:39for its pretty looks.
49:40It's called frit,
49:42a ceramic paint.
49:43Its main purpose
49:45is to protect the window
49:46from ultraviolet rays.
49:48It also creates
49:49a rough surface
49:50for the adhesive
49:50to cling to.
49:52Now, if you see
49:53a pink lump
49:54of adhesive
49:55in the corner,
49:56please do not touch it.
49:58It's actually
49:59someone's old bubble gum.
50:01If you take a look
50:03at the bottom of the lock,
50:04chances are
50:05you'll see
50:05one or two little holes.
50:07This is to let water out
50:09from the inside
50:09that may have been trapped
50:11due to rain.
50:12This mini-draining capability
50:14prevents the inner working
50:16from rusting over
50:17or freezing in place
50:18if the weather's very cold.
50:20If, in another situation,
50:22the lock becomes stuck,
50:24you can ease
50:25an oil-based product inside
50:27to lubricate the lock
50:28and get it working again.
50:31If you've lost the key
50:33and want to ease
50:34your frustrations,
50:35you can yell
50:36into the holes.
50:37It won't do anything
50:38to unlock it,
50:39but it may help you
50:40feel a little better.
50:42Some dress shirts
50:43have a fabric loop
50:44on the back.
50:45You guessed it!
50:46It's used for
50:47hanging the shirt up.
50:49The loops were reportedly
50:50first used in the navy,
50:52as it was easy
50:53to simply hang them
50:54on the wall.
50:55During the 1960s
50:57in colleges,
50:58the fashion of the day
50:59was to wear the shirt
51:00buttoned all the way
51:01to the top,
51:02which made them
51:03difficult to hang.
51:04So designers began
51:06putting the loop
51:07on the back.
51:08If the student
51:08removed the loop,
51:10it signified that
51:10they were going steady
51:11in a relationship.
51:13Unless your friend
51:14ripped one off
51:15for a prank,
51:16now everyone's asking
51:17whom you're with.
51:19There's a little more
51:20to this story,
51:20but we haven't got time
51:22to hang around.
51:24And yes,
51:25that's a bad pun.
51:26On purpose.
51:27It's what I do.
51:29Ever wondered
51:30why coins have
51:31those little ridges
51:32along the edge?
51:33It's a leftover
51:34from earlier times
51:36when they were worth more.
51:38Counterfeiters
51:38could easily file
51:39the edges off
51:40to sell as gold
51:41or silver coins
51:42to make some profit.
51:44The ridges were created
51:45so it was much easier
51:47to tell which of the coins
51:48had been altered.
51:49It's not needed today,
51:50but the coins still
51:52have that altered style.
51:54If you ever get
51:55really bored,
51:56you could try counting
51:57how many ridges
51:58there are.
51:59Actually,
52:00that is a very boring idea.
52:01Forget that
52:02and watch another
52:03Bright Side video instead.
