00:00I have a collection of questions you've always wanted the answers to. Let's go!
00:07First, an observation. Cookies and baguettes are basically kinds of bread.
00:12So my question is, why when left outside for the night, a cookie gets soft and a baguette becomes hard?
00:20It doesn't make any sense.
00:23Well, the thing is, cookies are sugary bread.
00:26The sugar and salt in them soak up the moisture from the atmosphere, so they get soft.
00:33Baguettes don't have much salt and sugar, so they don't attract water and just dry out.
00:41Superglue sticks everything to everything, but how come it doesn't get stuck to the tube?
00:46Turns out that the glue needs some compound with hydrogen to polymerize.
00:52In the tube, there's just oxygen and no water, but outside, there's plenty of moisture.
00:59Also, this explains why the stuff always sticks so well to your fingers.
01:04They're warm and perfectly moist.
01:08I'm sure you cried at least once when cutting an onion.
01:11Why does it happen?
01:13So onions and garlic contain amino acids, and one of the compounds gets decomposed when being sliced.
01:21It turns into an irritator when it comes in contact with water, in particular, your eyes.
01:27Your eyes release tears to wash the irritant away, so that's why you cry.
01:33There are a couple of tricks that can prevent it.
01:35When cutting an onion, try keeping a sugar cube between your teeth.
01:39It'll absorb the irritant.
01:40Another life hack is to hold a small piece of bread between your lips.
01:44It can help you too.
01:48Why do you see things when rubbing your eyes?
01:51These colors and shapes are called phosphenes.
01:53The reason why you see them is that when rubbing, you increase the pressure in your eyeballs and activate the
02:00neurons of the retina that process visual information.
02:03Once they're activated, your brain interprets it as seeing something.
02:09When you don't get enough sleep or are just too tired, you get those dark circles around your eyes.
02:15Want to know why?
02:16The skin under the eyes is very thin, so blood vessels are very close to the surface there, and you
02:22can see any difference easily.
02:24If you have a lack of sleep, your skin gets paler, and the blood vessels are even more visible.
02:31So you can see those dark circles showing through the skin.
02:34Also, with age, the skin naturally gets thinner, so that's why older people tend to have dark circles.
02:41But if you're young, just try to get more sleep.
02:46Let's pay a bit of attention to backpacks.
02:49They have a few interesting features.
02:51First, some of them have sternum straps, and they are quite helpful.
02:55They allow you to redistribute the weight of the backpack a bit, lifting some of it from your shoulders.
03:01Not much, but just enough to make your backpack lighter and easier to carry.
03:07And, of course, the sternum straps prevent the shoulder straps from sliding off.
03:13Okay, the next thing is gear loops.
03:15And probably from the name of it, you already have an idea of what you need them for.
03:20You can strap in some useful gear you need with you, like trekking poles or shovels.
03:26Some gear will need to be secured to do it.
03:29Drop the handle through the loop and rotate it upward.
03:32Then, secure it with the elastic hook at the top, and you're golden.
03:37And yes, all backpacks have loops.
03:40Actually, I never thought of their purpose until today.
03:43Some people say that if you slide your thumbs through them,
03:46it makes the backpack sit tighter on your back, making it more comfortable.
03:51Other people just rest their hands there.
03:53But the reason why they're there is probably to prevent the ends from sliding back from the buckles.
03:59That would be quite a headache to slide them back all the time, right?
04:05Okay, let's look into some other ordinary stuff we've never paid attention to.
04:10Let's take, for example, jeans.
04:12They have those metal rivets.
04:15It turns out that they've been there as long as jeans exist.
04:19Jacob Davis, the man who made the first pair of jeans,
04:22added copper rivets to places where the pants were more likely to rip to make them stronger.
04:28So, it was a crucial detail to keep jeans together.
04:31Today, they have a more decorative purpose because they're distinctive and traditional for jeans.
04:39Also, many zippers have the letters YKK engraved on them.
04:44Those are the initial letters of Yoshida Kogyo Kabushiki Gaisha.
04:49It's the name of a Japanese company that can be translated as Yoshida Manufacturing Shareholding Company.
04:55It's the largest zipper manufacturer in the world,
04:59so all zippers produced by them are marked with these letters.
05:03It's estimated that the company produces half of all zippers in the world.
05:09That's why you see their zippers more often than any others.
05:15Have you noticed that canned and bottled soda seems to taste different?
05:19You're not wrong.
05:21That's actually true.
05:22And there's even science behind it.
05:25Chemists say that aluminum cans have a polymer layer that absorbs some of the soda's taste.
05:30So cans indeed change the taste.
05:33Chemicals in a plastic bottle can add some acetyl-dehyde,
05:37a by-product that gets formed while plastic is melted, to the drink.
05:41So, they also change the taste a bit.
05:44You never really drink the original drink.
05:47If you want to try the real thing, buy sodas in glass bottles.
05:51When soda is stored this way, its taste is the most similar to the original one.
05:59Plastic bottles with soft drinks have five bumps on the bottom,
06:02and water and juice plastic bottles have almost flat bottoms, except for a little kink.
06:08It's not random.
06:09A plastic bottle is made by putting a plastic tube into a mold
06:13and blowing some air inside to make it expand until it takes the needed shape.
06:19The problem is that at the bottom,
06:21the bottle will always have an outward kink that will make the bottle unstable.
06:27To avoid it, some air is also pushed inward from the bottom,
06:32creating that small punt at the base of it.
06:35Flat bottle bottoms are common because they need less plastic to be made,
06:39but soft drinks and sparkling water need special treatment.
06:43These liquids have internal pressure that can push the plastic outward,
06:48messing up with the punt and the stable form of a bottle.
06:52So, soda bottles have a curved shape
06:55because this way they're more pressure resistant.
06:59Compare folding a regular piece of paper to folding a paper too.
07:04The latter will have more resistance.
07:06In the same way, curved plastic is more resistant to any pressure.
07:12Take a closer look at your bag of chips.
07:15You can probably find these little colored circles.
07:18They're made by the manufacturer to test the print that is used on the package.
07:23They're called color control patches.
07:26The circles are not the same palette as the final package.
07:30They're layered on top of each other to achieve the final color of the bag.
07:35So, why do manufacturers need them again?
07:38Imagine that something is off and the printing machine prints a bunch of wrong packages.
07:43That's a lot of wasted money.
07:46So, these control patches are there to make sure that the final print is going to be correct.
07:51If they're off, the manufacturer will know that the whole package is going to be off too.
07:58These patches allow the printers to find a surplus or a deficiency of color and solve the issue.
08:04But don't worry if you don't find these circles.
08:07They probably just got cut off.
08:11Take a good look at a milk jug.
08:13There's often an inverted circle on one of the sides.
08:16This dimple is there to make the jug more resistant and to prevent it from rupturing if the jug falls
08:23on the floor.
08:24The dimple gives some more space for the liquid to expand.
08:29Also, as the expiration date approaches, the microbes in the milk start to expel some gases.
08:35As more and more of them get trapped inside, the pressure in the jug rises.
08:40The dimple accommodates the expansion and prevents the jug from bursting.
08:49Have a good look at the front of your sweatshirt.
08:52Okay, let's ignore the pizza stains for now.
08:54Ever notice that V-shape right at the bottom of the collar?
08:57That small V-patch isn't just a decoration.
08:59It serves more than one purpose.
09:02Made from a double layer of webbing material, just like waistbands and cuffs,
09:05these inserts allowed the wearer to put on the sweater without losing any shape over time.
09:10As the sweatshirt would be pulled down over the head,
09:13the V-insert would stretch and flex to allow a lot of wiggle room.
09:17The other benefit the V-pattern gives is to absorb all that sweat.
09:21The chest is a major area of perspiring.
09:24Just look at soaked shirts after doing something physical.
09:27Although, the V-insert can only take so much.
09:31That extra pocket on the right side of a suit jacket is called the ticket pocket.
09:35They used to store coins for people on horseback to pay tollbooths without opening their jackets.
09:40When train travel became more popular, they were perfect for tickets and passes.
09:45As for the left chest pocket, it's used to store handkerchiefs,
09:48keeping them away from the other cluttered and dirty pockets.
09:52Metallic zippers have a hidden lock built in.
09:54Next time you've put on a pair of pants, shorts, or skirt,
09:58never leave the zipper handle in an upward position.
10:01Push the little zipper tab downwards, and it'll automatically lock.
10:05To mute your annoying beeping microwave,
10:07look closely at the front panel for a sound button.
10:10It may have been there all along, just begging to be pressed.
10:13If there's no button, try pressing and holding 1, 0, stop, or cancel.
10:18It will either result in turning off the beeping sounds or activating a lock feature.
10:23Of course, if your microwave doesn't have any mute function at all,
10:27you'll just have to keep running to stop the timer late at night.
10:30Nintendo Switch cartridges have a hidden safety function,
10:33and it's going to leave a bad taste in your mouth.
10:36Although non-toxic,
10:37denotonium benzoate coats the cartridge in a sour, peppery, and bitter substance
10:42to prevent kiddos from swallowing them.
10:44This chemical compound is one of the most bitter flavors known to humanity,
10:48commonly used to keep people from consuming things they're not meant to.
10:52There's not much privacy while using a public toilet,
10:55especially when the door doesn't reach the floor at all.
10:58But these gaps are there for emergency access,
11:01in case the person inside needs immediate help.
11:04The gap also works for ventilation, thank goodness,
11:07and to stop people from lingering around the toilet too long.
11:10Toothpicks have a built-in holder to prevent you from just leaving them on the table.
11:14Just break off the top, it's that simple.
11:17Place that on your table and your toothpick between the notches.
11:20Pointy end up, of course.
11:22Now, it won't touch the table and get all dirty.
11:24You can do the same with disposable chopsticks.
11:27Break off the top piece before you pull them apart.
11:30Those tiny dimples on golf balls actually give a greater lift to the ball
11:34and reduce air resistance, meaning the ball can go further with them.
11:38These dimples come in spherical and hexagonal shapes,
11:41with each slightest change affecting the ball's performance.
11:44So, choose them carefully.
11:47Plastic wrap boxes have hidden little holders
11:49that stop the roll from jumping out of the box.
11:52They're little cardboard tabs on the sides that lock into the tube inside
11:56while making it easy to glide the film out.
11:59Just push them in and never be frustrated again.
12:02Gosh, I wish that would work with other stuff.
12:04The seven spikes on top of the Statue of Liberty's crown
12:08don't represent the seven seas and the seven continents at all.
12:11They're representing the sun's rays,
12:14giving a halo to show that she is divine.
12:17In the United States,
12:1812 different Federal Reserve Banks print all the money.
12:21So, if you want to know where your money comes from,
12:24just look for these small codes.
12:26A1, Boston
12:27B2, New York
12:28C3, Philadelphia
12:30D4, Cleveland
12:32E5, Richmond
12:33F6, Atlanta
12:35G7, Chicago
12:36H8, St. Louis
12:38I9, Minneapolis
12:39J10, Kansas City
12:42K11, Big D, Little A, Double L A S
12:45It's a song.
12:46L12, San Francisco
12:48Never call it Frisco.
12:50Meanwhile, the bristles on the side of every escalator
12:53are in place to encourage people to stay away from the edge,
12:57meaning they're less likely to face a mishap with a trapped bag or shoelace.
13:01Did you hear about the octopus caught on the escalator?
13:03It was a stretch.
13:05Old-fashioned pin cushions that are large tomato with a strawberry attached
13:09are more than a place for your needles.
13:11The strawberry contains an emery board.
13:13When you stick your pins and needles into the strawberry,
13:16the emery board keeps them rust-free and sharpens them as well.
13:20Some people still forget to engage the hose from their car after filling up with gas.
13:25Luckily, a lot of gas companies realize this,
13:27so if you happen to drive off with a hose still attached to your car,
13:31there's a magnetic connector that disengages when pulled.
13:35Those different colored bread tags use a color-coded system to show the day that they were baked.
13:40They are usually blue tags for Mondays, green tags for Tuesdays,
13:44red tags Thursdays, white tags Fridays, and yellow tags for Saturdays.
13:49On the back of most beauty products,
13:51you'll find a small symbol on the back that indicates how long it'll stay good for.
13:56For example, 2M means two months after opening.
14:00Some jackets have those extra flaps with a button on the shoulder,
14:03and they actually have a use.
14:05These are perfectly designed for holding your purse, backpack, or bag in place and secure.
14:11Pom-poms on the top of beanies were never just a fashion statement.
14:14They were for protection, placed on top of the headwear to protect sailors
14:18from accidentally hitting their heads while moving around on a ship.
14:22Pom-poms touch the roof, so don't go any higher.
14:26They don't appear on every type of measuring tape,
14:28but diamonds or black circles are there to help contractors
14:32measure the proper placement of studs in a wall.
14:35Those little holes on your baseball cap aren't some fashion trends
14:39that stuck around for years and have never been changed.
14:42These holes are actually called eyelets,
14:44and they're to keep your head well-ventilated, not for appearance.
14:48If you have YKK printed on your zipper,
14:51they're not some secret code to be cracked.
14:53Those three letters appear on so many zippers globally
14:56because they're the symbol of the world's most universal zipper manufacturer,
15:00the YKK Group.
15:02Every can of soda comes with a tab for easy opening of the tasty beverage,
15:06and every single one of them has a relatively large hole in the top.
15:10While it can make it easier to get your finger under the tab to get your soda,
15:15its intended purpose is a straw holder.
15:17Spin the tab over the opening and place your straw through it to secure it in.
15:22Disposable lids do a great job of keeping your drink inside the cup,
15:25but that's not its only purpose.
15:28When you're ready to sip on your drink,
15:30the lid has specially designed ridges to double it as a coaster
15:33and hold on to the bottom of your beverage tightly.
15:36The tiny black dot between the lens and the flash on the back of your iPhone
15:40is actually for a great purpose.
15:42It's the third microphone to provide superior sound quality
15:46by eliminating background noises
15:47and to pick up your voice much clearer in a crowded environment.
15:51Gas cans that have two holes with caps
15:54aren't there to fill different-sized equipment.
15:57The second hole is meant to be uncapped
15:59before you pour your gas to prevent that glugging effect.
16:02By allowing more airflow through,
16:04the smoother the gas will pour out.
16:07That little arrow next to the gas symbol on your car's dashboard
16:10shows you which side your gas tank is on.
16:13It'll help you when you go fill up your gas tank,
16:16especially if you're borrowing a different car than your own.
16:19Look at a check and see MP near the signature line.
16:23That means the check printer used microprint
16:26as one of the check's security features.
16:28The lines look like a regular line to the untrained eye,
16:31but they're words like the bank's name,
16:33authorized signature, United States government,
16:36or even original document.
16:38That little disc that's underneath bottles
16:40isn't just a leftover part of the production process.
16:43It creates an even tighter seal with the lid.
16:46So, even if the bottle was turned upside down,
16:49the liquid doesn't leak out everywhere.
16:51The plastic disc keeps carbonated sodas carbonated for longer with this seal.
16:56The indent in the bottom of wine bottles is called a punt.
17:00But it's not just something to help you hold onto the bottle.
17:03The punt makes the wine bottle stronger,
17:05so if dropped, the cork won't fly across the room with all that pressure.
17:10The Queen's Guard all appear to have the same uniform,
17:13with a shared role of standing stoically for a long time.
17:17But if you look closely at their hats,
17:19there are five different types.
17:22The Grenadier has a white plume.
17:24The Coldstream has a red one.
17:26The Irish, a blue plume.
17:28The Welsh, green and white.
17:30And the Scots Guard has none.
17:33Their different divisions perform similar ceremonial duties at Buckingham Palace.
17:38But they have other actual rules as well,
17:41suited to their specialization.
17:44When peeling your boiled eggs,
17:46you can see a hidden layer under the shell.
17:48These two membranes, an inner and outer one,
17:51are made from the same stuff as your hair,
17:53keratin.
17:53It protects the inside from bacteria and stops liquids from escaping.
17:58You use X in your texts, which represents a kiss.
18:02It's been used this way for a very long time.
18:05Its original purpose dates back to the Middle Ages,
18:07where it was a representation of a person's faith, honesty and sincerity.
18:13Those that would sign off with an X would kiss it after signing as a display of a sworn oath.
18:20The X's meaning later changed to represent the action of kissing.
18:24And the first document showing this was a letter dating back to 1763,
18:29written by a naturalist, Gilbert White, who sent it to his wife.
18:34William Shakespeare is a name familiar to everyone.
18:37However, we don't know whether this was the actual way his name was spelled.
18:41And neither did he.
18:44He signed 80 different variations of his name spelling on all his works.
18:48Historians haven't a clue which the correct spelling is.
18:52The version that we know of was only used on two of his plays.
18:57Different forms of alarm clocks were invented as far back as 348 BCE,
19:03with many versions throughout the world, all with complicated mechanics.
19:08Unaffordable to mostly everyone, they didn't catch on.
19:11Alternate methods to wake up in the morning started to be used in the 1800s.
19:16One process involving knocker-uppers was common in some countries.
19:21A person visited your house every morning to knock on your door four times.
19:27Inventor Antoine Redier felt that he should be woken only when he felt it necessary.
19:32So, in 1847, he invented the first adjustable alarm clock.
19:38Tennis balls in Wimbledon must be kept at a perfect temperature to ensure they bounce at a consistent level.
19:45They're stored at 68 degrees Fahrenheit,
19:48so they're cold enough that the molecules inside the ball shrink, ensuring they bounce lower.
19:53Then, they're continuously swapped throughout a match as they expand by being hit too much, becoming too bouncy.
20:00Wimbledon goes through 50,000 tennis balls each year.
20:05You enjoy the smell of a freshly mowed lawn, as you associate it with the weekends and summer.
20:11But that smell is a sign of stress made by the grass.
20:16Grass evolved to emit various elements when being eaten by bugs.
20:20This signal attracts predator insects to remove them.
20:23But unfortunately for the grass, there's nothing large enough to deter a lawnmower.
20:29There is no oxygen inside your packet of chips.
20:32If there was, it would influence the combination of molecules forming inside, spoiling the chips faster.
20:39The packets are instead filled with nitrogen, which pushes oxygen out.
20:43And this extends the shelf life and quality of your chips.
20:49You're traveling by plane overnight and just can't get to sleep.
20:53And the first night in a hotel wasn't great, regardless of how comfy the bed was.
20:58This is because of a human evolutionary trait called the first night effect.
21:04When you sleep in a different place than your home,
21:07the left side of the brain responds to more sounds while you're asleep.
21:10It continues to analyze your surroundings without you realizing,
21:14acting as though it's on a night watch and keeping you alert for any potential dangers.
21:20Most animals have this trait, although it's a lot more subtle in humans.
21:25But it's still effective enough to make sure you get your peanuts.
21:30Before playing basketball with hoops, you would have instead been playing with peach baskets.
21:34When the game was invented in 1891, a peach basket was used, with the bottom of it cut off.
21:40But it only took 15 years for players to grow tired of constantly collecting the jammed balls
21:45and to remove the basket altogether.
21:49When you click your fingers, the snapping sound isn't from the physical click of finger and thumb.
21:54The noise actually comes from the finger hitting the palm.
21:59The instant film for the first Polaroid cameras didn't have their own coating after taking a photo.
22:05To develop it, you applied it yourself.
22:08Waiting for it to dry took a long time, so shaking it sped up the process.
22:12Then, from the 1970s, the film provided everything required for the photo to develop,
22:18making the popular craze of shaking Polaroids pointless.
22:22Shaking the photo can cause the ink to wave or blur before drying properly,
22:26so you shouldn't actually shake it like a Polaroid picture.
22:29And just wait patiently instead.
22:33Bug spray doesn't repel all bugs, especially the worst of them all, mosquitoes.
22:38It does cover the scent of carbon dioxide, which is what attracts mosquitoes.
22:43But the spray only protects you for a short distance.
22:47Mosquitoes can also track carbon dioxide over long distances.
22:51They will continue to stalk you until they find a gap in your invisible bug shield.
22:56A great alternative is lavender, which contains linalool.
23:00This fragrance completely overloads the mosquito's senses, making it unable to track you.
23:06The half-belt on the back of some jackets appear like a fashion accessory.
23:11It was initially designed that way for larger jackets,
23:14as they could also be used as a blanket to wrap around oneself.
23:18The belt's position helps hold the material together,
23:21so it's easier to walk with whilst keeping you warm.
23:25Ketchup wasn't originally intended to be your favorite condiment.
23:29In 1834, a physician, John Cook, sold ketchup as a cure for indigestion.
23:36It was an immediate hit,
23:38and today, 10 billion ounces are purchased annually in the USA,
23:43although not as the intended medicine.
23:46Thomas Edison made over 1,000 inventions,
23:50and one in particular, the lightbulb, is most famously linked to him.
23:54However, he didn't actually invent it.
23:57Warren Delarue, a British chemist,
23:59had solved this scientific challenge 40 years earlier.
24:02There were also 20 other inventors who made alternate versions before Edison did.
24:08But earlier varieties relied on cotton thread and only lasted up to 14 hours.
24:14Edison, in 1880, used a carbonized bamboo thread instead,
24:18and his worked up to 1,200 hours.
24:21It became the most commercially viable lightbulb,
24:24and today's ones are similarly shaped to Edison's original.
24:29The first treadmill was used in England in 1818.
24:33It was a large wooden cylinder with a handrail,
24:36although it wasn't used to keep fit.
24:39Convicted criminals would be forced to use these for up to 10 hours per day as a punishment.
24:45The energy output potential was realized,
24:47and soon it was built to work with water pumps and grain grinders.
24:52It was so effective that it was used in all prisons throughout the country.
24:55But in 1902, it was decided that it was too harsh and stopped.
25:00And now, this cruel punishment is mainly found in gyms.
25:05During the 1940s, there was a shortage of cocoa,
25:08and it was important to find a solution to this problem.
25:11A production company found a way by mixing only a small amount of cocoa with hazelnuts and milk,
25:17and the original Nutella was created.
25:20It started out as a loaf spread, like a stick of butter.
25:24It then transformed into a creamier version inside a jar in 1951.
25:29But it wasn't until 1964 that it was given its famous name.
25:34Your passport might be a dark shade of either green, blue, or red.
25:39The darker color not only makes them appear more official,
25:42but is intended so that through its journeys,
25:44the dirt that's collected is more easily hidden.
25:49Wasabi was first used back in the 8th century.
25:52It wasn't meant as a spicy condiment as it's served with sushi today.
25:57Initially, it was used for its antimicrobial properties
26:00that help avoid the harmful reactions to fish with sushi that's a bit too old.
26:08Now here's a trick.
26:10Instead of putting the box grater vertically on top of a plate,
26:13put it horizontally, with no plate underneath, of course.
26:16This way, you won't risk scraping your knuckles,
26:19because only your fingertips will eventually touch the grater
26:22when you reach the end of the process.
26:24Also, it gives the grater more stability,
26:26when otherwise you'd have to balance the grater
26:29or even hold it in the air with the other hand.
26:31When you're done,
26:32or when there's just too much grated stuff on the bottom wall of the grater,
26:36simply turn it on its side to pour the contents into the bowl or plate.
26:41Flowers in a vase would stay fresher for longer
26:43if not for the bacteria that breed in the water.
26:46Since copper has some antibacterial properties,
26:49dropping a penny into the water will help keep the microbes at bay
26:53and let you enjoy your flowers for that little bit longer.
26:56An easy way to check if your bed linen has dried completely
27:00is to put a small mirror in between the layers for about 5 minutes.
27:04If the mirror has steamed up when you pick it up,
27:06it means the sheets are still a bit damp.
27:09Let them dry until the mirror stops getting cloudy.
27:12A damp bed is a lovely breeding ground for fungi and bacteria.
27:17Okay, I'm in.
27:18If you have a not-very-healthy habit of eating in front of your computer,
27:23you'll be surprised at how much crumbs and grime there is inside your keyboard.
27:28Now, you can just turn it over and shake it vigorously, of course.
27:32But that's not very good for any piece of tech, you know.
27:35So instead, take a post-it note and run its sticky part over the keyboard.
27:40It will collect the little pieces of trash like magic.
27:43Even a better way to do it, though, is to take a slime and stick it to the keyboard.
27:48Then take it away, squeeze it, and stick again in another part.
27:52The slime will fill the entire space between the keys,
27:55and its sticky properties will let it gather every little bit of garbage.
28:00Separating egg yolks from whites is easier using a plastic bottle.
28:04Break the necessary number of eggs into a bowl,
28:07and then take an empty plastic bottle and squeeze it.
28:10Hold the bottle over the yolk and release.
28:12It'll pull in air and the yolk together, leaving the white in the bowl.
28:17Repeat with the rest of the yolks, and you're done!
28:19And that's no yolk!
28:22If you're tired of spitting out the stones when eating cherries,
28:25or want to make a cherry pie, push the stones out with a straw.
28:29Also, many garlic presses have a special tool on their handle that can be used exactly for that.
28:36Cleaning a blender can be a nuisance if you do it manually.
28:39Instead, fill it with hot water and add some liquid soap or detergent,
28:43then run it for about 10 seconds.
28:45Rinse it afterwards, and it's clean.
28:48Plaster walls can crumble, flake, and spread dust all over the floor when you hammer nails into it.
28:54Cut a strip of masking tape and stick it to the place you want to hammer a nail in.
28:58The tape won't let the plaster crack and crumble, leaving the hole neat and clean.
29:03Small scratches and dents on wooden furniture can be removed with some toothpaste or a walnut.
29:10For toothpaste, rub a pea-sized amount of it into the scratch until it's gone,
29:15then wipe the leftovers with a damp cloth.
29:17For a walnut, take a half of that brain-shaped nut and rub it into the dent.
29:22Then rub the area with your fingers and buff it with a soft cloth.
29:26This will help the wood absorb the oil from the nut, making the scratch sealed and gone.
29:32The sticky residue on jars left after you remove the stickers won't be easily removed by water and detergent.
29:38So, take some vegetable oil instead.
29:41Soak a cotton pad in it and wipe the sticky surface.
29:44Let it sit for a while and then wash the oil away together with the residue.
29:49If you can't comfortably reach the wick of a candle with a lighter,
29:53hey, take a stick of spaghetti.
29:55Light up its end and you'll get a burning stick that's easy to use for hard-to-reach places.
30:01Now, next time your razor blade's getting dull,
30:04try rubbing it backwards on a pair of jeans for regular upkeep.
30:08Not while you're wearing them, of course.
30:10Make sure you keep the blades dry, too, or even kept in mineral oil.
30:14That'll stop them from rusting.
30:15Keep all those jelly, ketchup, peanut butter, and mayo fresher for longer in your fridge
30:21by turning the contents upside down.
30:24This creates a partial vacuum inside the container, helping prevent mold growth.
30:29Storing ice cream upside down will prevent freezer burn, too.
30:33To bring your permanent marker back to life,
30:36simply put a few drops of rubbing alcohol into the felt material inside and shake.
30:41Once the felt absorbs the rubbing alcohol for a couple of minutes,
30:44the marker will be almost as good as new.
30:48Now, don't keep throwing away lettuce that goes black too quickly.
30:52Covering it with a dry paper towel and then placing it in an airtight container
30:56will help it keep fresher for much longer.
30:58This goes for any leafy greens you've got leftovers of.
31:02That sharpish bit sticking out of the cap of your favorite cream is there for a reason.
31:08These tubes are usually sealed with foil,
31:10so unless you love breaking your nails trying to open them,
31:13just flip the cap over and push.
31:16Your bobby pins might not stay in place if the grooves aren't facing the right way.
31:21They should always be on the bottom, close to your head.
31:24Still coming loose?
31:25Well, put a squeeze of hairspray right onto the bobby pin before you put it in your hair.
31:30Now, your cotton rounds pack has those strings on it,
31:33so you can hang it on a handy hook in the bathroom.
31:36But there's no need to loosen and tighten it back up every time.
31:40Check out the bottom of the pack.
31:42It has a perforated line.
31:44Tear it open carefully, and you're good to go.
31:47Two zips too much?
31:49Maybe.
31:50But they come in handy as a clever anti-theft device.
31:53Just lock them together.
31:54Now, no one can open your backpack.
31:57Don't have a lock on you?
31:58You can also tie them together with some string,
32:01or even just a paper clip.
32:03Anything to slow those pickpockets down.
32:06That tiny little button on the back of a shirt collar is used to hold your tie in place.
32:11Hey, you don't want your tie trying to escape back there.
32:15Shoe manufacturers care about their customers,
32:17so most running shoes now have a special anti-blister system pre-installed.
32:23Sounds intense, but it's basically just that extra hole on top of your sneakers.
32:28Make a loop with the extra hole, inserting the lace backward.
32:31Cross your laces and put them through the loops.
32:33Now, pull the laces down to lock your foot in place.
32:37Now, run.
32:38Yeah, go ahead.
32:40Car headrests are all about comfort,
32:42and detachable headrests are all about safety.
32:45If you pull the headrest out, you'll see two sturdy metal bars.
32:49If you ever get locked or trapped in your car,
32:52you can use the bars to smash the window and get out.
32:56If you've got some pesky parsley stuck in your teeth, try this tip.
33:00It can be hard to get it out with loose floss.
33:03You need more tension, so just tie it in a knot.
33:06It's not an accident that soy sauce bottles have two spouts.
33:10The sauce is liquid, and it flows out of the bottle pretty easily once you turn it over.
33:15Most Asian food lovers have spilled it at least once in a lifetime.
33:19That's why nowadays, restaurants prefer serving soy sauce in special bottles that have two spouts.
33:25This design allows you to control when and how much sauce will come out.
33:29Just put your finger on one spout when you pour the sauce through another.
33:33If you press your finger tightly to the spout, the sauce will stop flowing,
33:37and if you remove your finger, it'll flow again.
33:41And don't forget to ask your server,
33:43Hey, wasabi!
33:45Alright.
33:46A hair straightener is an excellent tool,
33:48not only for treating your natural curls,
33:50but also for fixing crumpled money or documents.
33:53You can also use a regular iron for this purpose.
33:56Just make sure you don't turn on steaming mode,
33:59otherwise there's a risk of damaging the paper.
34:02Hairbands are good not only for getting your hair done,
34:05but also to open a glass jar with canned food.
34:08Your hands might slip on the tightly closed lid,
34:11and if you don't open the can from the first attempt,
34:14your palms tend to get sweaty, making the task virtually impossible.
34:18So, put a hairband on the lid to fix your hand and make your grasp stronger.
34:24A simple rubber band will do as well.
34:26Now, it's time to take my sweaty palms and go.
34:29Okay, I know it's kind of cold to the touch,
34:32especially on a freezing winter's day,
34:34but did you know that brass doorknobs actually serve a purpose apart from looking classy and shiny?
34:39Since it's a copper alloy, brass has antimicrobial properties.
34:42That means it can help get rid of harmful germs and bacteria,
34:46sometimes in up to two hours.
34:48In high-traffic areas, that's all the more useful,
34:51but since brass is much costlier than other metals like nickel and steel,
34:55you barely see these types of doorknobs anymore nowadays.
34:59Speaking of lovely multi-purpose items,
35:01most screwdrivers have a tiny little secret of their own.
35:04They can sometimes be slid through a wrench
35:06so that they can be used to create more torque when twisting,
35:09not to mention the uses when it comes to bolts in hard-to-reach places.
35:14There's a reason why buttons on women's shirts are for the left-handed,
35:18and it has nothing to do with fashion.
35:20This practice dates back to the times when chambermaids were helping ladies dress themselves,
35:25and it was easier for them to perform their job with this orientation.
35:29Having the buttons placed as such indicated a sign of wealth,
35:33so it's easy to imagine why the practice carried on,
35:36even though most people dress themselves nowadays.
35:39Next time you receive a package in your mail,
35:41take a look at your box cutter.
35:44If it features some diagonal lines on the blade,
35:46you're in for a little design perk.
35:48Turns out that these are blades that snap off.
35:52Continuously cutting cardboard can dull the sharp edge of the blade.
35:55To help prevent the need to buy a brand new box cutter,
35:58the top segment along the next line can be broken off to reach a new sharp edge.
36:03To do this, check out the small hole at the base of the tool,
36:06sometimes called the blade snapper.
36:09The people that first came up with this brilliant invention were engineers,
36:13inspired by the way chocolate bars are segmented.
36:15Hold on a minute, don't throw away the cardboard package just yet.
36:19Most likely, you'll have some silica gel packets somewhere at the bottom of the box.
36:23Since this gel is basically a drawing tool,
36:26it gathers up the moisture out of its environment,
36:28so you can store these packets for further occasions.
36:30Whether you'll need to dry out your phone or some other electrical object,
36:35you can place them in a container next to the silica gel to reduce the damage.
36:39You don't have to be a mechanic to know when a standard car tire needs replacing,
36:44since they come equipped with a neat indicator.
36:46Take a closer look,
36:48and you'll see that treads within the tire are a bunch of rubber notches.
36:52When the treads are evened out with the perpendicular bars,
36:55it's a sign you need to book an appointment with your local car service.
36:59Since most likely, the tires have lost most of their traction
37:02and may not be safe for driving any longer.
37:05The upper corners of a car windshield feature textured black dots
37:09melted into the glass edges.
37:11This neat add-on isn't there for design purposes.
37:14It's called frit glazing,
37:16which means that a special type of ceramic paint
37:19is added to the window for protecting its sealant from UV rays.
37:23It also conceals and creates a coarser surface
37:27for the adhesive used to set the window in place.
37:30Whenever you're up for a drive,
37:32check out if there's a small tab under your car's rearview mirror.
37:36Bet you didn't know it's there to help switch the mirror
37:39from daytime to nighttime views.
37:42It uses a prismatic glass technology to blur the reflection
37:46and reduce the glare of headlights behind you in traffic.
37:50People came up with these manually tilted mirrors in the 1930s,
37:53but they became standard somewhere in the 1970s.
37:57While you're in the car,
37:58check out the headrests,
38:00as you most likely don't know that they carry a little disguised purpose.
38:04Of course, they're adjustable to accommodate passengers of any height
38:07so that they get the proper support for their heads and necks.
38:10The hidden feature is that they are detachable
38:13and come with two very solid metal bars.
38:16Should you ever find yourself stuck in a car
38:19and need to make a fast getaway?
38:21These bars come in handy to crack out the car windows.
38:24So you're out for a drive and you're suddenly out of gas.
38:28What I'm about to describe sounds more like a meme
38:30than an actual situation bound to happen.
38:32But what if you're in such a hurry
38:35that you accidentally drive off with the gas nozzle still in the tank?
38:38Well, the nozzles have been designed
38:41to prevent any hazards from happening, rest assured.
38:44They feature a breakaway device
38:46that will allow the hose to separate
38:48when taken out with enough force.
38:50Initially designed in the early 20th century
38:53to be worn exclusively by basketball players,
38:56sneakers soon became one of those fashion fundamentals,
38:59similar to jeans and leather jackets.
39:01If you take a closer look at them,
39:03you'll see they have two extra holes on the side,
39:05similar to the shoelace holes.
39:07They're manufactured as such,
39:09not only to provide extra ventilation,
39:11but to allow people to get extra creative
39:13with their laces when wearing the shoes.
39:15Admit it, you've always thought that chopsticks
39:18are merged at the end for the sole purpose
39:20of keeping them together
39:21until you're ready to dig into your meal.
39:23That may or may not be the whole truth.
39:26Under a more detailed inspection,
39:28the wooden tools feature a square-shaped end.
39:31Chopsticks manufactured like this
39:33date back to an old Japanese traditional design,
39:35which can help with breaking the ends easily.
39:38The separated end can then be used
39:41as a resting block for the chopsticks
39:42to keep it more sanitized
39:44in hopes it can be used again,
39:45since they won't be touching the table
39:47or any other surface.
39:50Women's bikes have a special design,
39:52which, surprisingly,
39:53has a historical and fashionable purpose.
39:56The lower frame is for the most part
39:58meant to make up for the generally shorter height of ladies,
40:01compared to that of the average gentleman.
40:03While that is the case for handlebars and saddles,
40:06the overall frame is lower for an additional purpose.
40:09Way back when women wore long skirts and dresses all day,
40:13every day they needed to make sure their outfits
40:15wouldn't get caught in the frame.
40:17That's how we came up with a lower-framed bicycle,
40:20perfectly made for women and their needs at the time.
40:24The fact that toothpastes are multicolored
40:27is not just a nice perk to make dental hygiene more fun.
40:30There's a secret meaning related to each of the colors,
40:32which dates back to the 1970s.
40:35In those days,
40:36people grew more and more interested
40:38in their oral health care,
40:40and as such,
40:41they were looking for products
40:42which could do more than merely clean their teeth.
40:45One company was the pioneer in that regard,
40:48adding mouthwash to its toothpaste,
40:50meaning the blue strip.
40:51They later added on the red strip,
40:54meant to feature ingredients
40:55which helped with gum care.
40:57Speaking of toothpaste,
40:59check the cap next time you open a new tube.
41:01You may be in for a little surprise.
41:03There's a pointed cone shape inside the cap,
41:06so you can puncture the seal of the toothpaste
41:08without cutting yourself or ruining your manicure.
41:11Not to mention,
41:12it's more hygienic
41:13since you won't be able to transfer germs
41:15or other bacteria into the product itself.
41:18On the subject of bathroom countertop items,
41:22toothbrushes come with a neat add-on
41:23hidden in the bristle patterns.
41:25Apart from making the toothbrush look cooler,
41:27they also do come with a practical purpose.
41:31Most toothbrushes come with a pattern of blue bristles
41:33intertwined with white ones.
41:35The blue dye is meant to fade out,
41:37signaling the time when you need to replace your toothbrush.
41:41Dentists say that toothbrushes should be replaced
41:43every three to four months,
41:45but it does serve as a great reminder
41:47in case you forget.
41:48Still love playing with Lego?
41:50Don't judge.
41:51Hey, it's a great hobby for all ages.
41:53Notice there's a hole on top of the Lego heads?
41:56Behold, you're looking at a safety feature
41:58that the people at Lego
41:59designed to prevent choking hazards.
42:02The most dangerous issue
42:04should a person swallow any of these pieces
42:06is the blocking of the airways.
42:08Designing a hole inside the Lego head
42:11helps the air to flow freely through the piece
42:13until it can be removed safely.
42:16We're now used to all sorts of modern light bulbs,
42:19some tubular, some shaped like diamonds,
42:21and some even twisted all together.
42:24Historically, light bulbs were round
42:26and the initial shape served a purpose in itself.
42:29It was mainly connected to the fact
42:31that glass bulbs were hand-blown,
42:33which gave them the round shape to begin with.
42:35The hidden practical reason
42:37was that the light bulb filament
42:38needed to be at the same distance
42:40from every surface of the glass sphere.
42:42The easiest way to achieve this
42:44was to make the glass in the shape of a globe.
42:49You just spent the entire morning
42:51running errands up and down the street,
42:53and you finally stopped to treat yourself
42:55to a cup of coffee.
42:56You enter the nearest coffee shop,
42:58place your order,
42:59and notice that, actually,
43:01you really need to use the bathroom.
43:03It's a regular-looking public one
43:05with multiple stalls.
43:06As you pick yours,
43:08the one in the middle,
43:09you get inside,
43:10and your mind starts to wander.
43:12Why on earth do bathroom doors
43:14have a half-inch gap
43:15between the door and the lock?
43:17And why on earth
43:18do they have a huge gap
43:19between the door and the floor?
43:21Can we have a drumroll
43:22for this moment, please?
43:24Well, my friend,
43:25there is not only one specific reason
43:27why public bathroom doors
43:29have so many gaps in them,
43:31but rather several.
43:32Public toilets are designed
43:34to make people spend
43:34as little time there as possible.
43:37You aren't supposed to feel comfortable
43:38or at home.
43:39So, the design would have
43:41to reflect this notion.
43:42Here come the gaps.
43:44In some bathrooms,
43:46gaps are so big
43:47that users may even feel
43:48self-conscious about
43:50doing their business
43:51out of preoccupation
43:52that the rest of the people
43:53standing in line
43:54will see them.
43:55Then, there's the matter of pricing.
43:58Making custom doors
43:59can be a heavy burden
44:00for the people
44:01building public toilets.
44:02This would mean
44:03understanding exact measurements
44:05so that doors would always
44:06fit the mold of the stalls
44:08it's supposed to be installed into.
44:10Now, not all the gaps
44:11in public bathrooms
44:12are necessarily the same size.
44:15They may vary,
44:16even if this variation
44:17is small and often unnoticeable.
44:20So, these gaps actually help
44:22to reduce the margins of errors
44:23and to turn production
44:25more cost-effective
44:26for the people financing them.
44:28In case a door comes wider
44:30or more narrow than it should,
44:32the gap regulates the differences
44:33and allows for their installation anyway.
44:36There is also the case
44:37of air circulation.
44:39The last thing you want to do
44:40in a public bathroom
44:41is to trap odors.
44:43So, you need a little space
44:45under and between the doors
44:46to allow the air to flow.
44:48Finally, the gaps
44:50are a big safety measure.
44:51It can always allow
44:52for people on the outside
44:53to see if someone inside a stall
44:55isn't feeling too okay
44:57and maybe need some help.
44:59And what about that extra hole
45:01in the upper part of the sink?
45:03It has a name in everything.
45:04The overflow hole.
45:06And it's designed
45:07to keep the sink from flooding.
45:09So, in case someone forgets
45:10and keeps the faucet going
45:12for too long
45:12or the sink gets clogged
45:14and water can't drain down
45:15from the main drain hole,
45:17the overflow hole
45:18comes in to save the day.
45:20Let's say it buys you
45:21a little time
45:22before you have
45:23the entire bathroom floor flooded.
45:25Have you ever noticed
45:26how satisfying
45:27closing the door of a car can be?
45:29Car manufacturers
45:30devote a great deal of time
45:32to designing these sounds.
45:34Studies have shown
45:35that they create
45:35a perceived sense of quality
45:37in the buyer.
45:38It all begins
45:39with the primary material.
45:41While older cars
45:42used to be made
45:43with heavier materials,
45:44car doors nowadays
45:45are produced
45:46with lighter tin,
45:47which can make
45:48a rather unpleasant
45:49metallic sound
45:50once you shut them closed.
45:52So, car companies
45:53employ sound engineers
45:54to ensure
45:55that there is
45:56the exact amount
45:56of foam, mats,
45:58and tin in a car's composition
45:59to make the most
46:01comforting sound possible.
46:02And what about
46:03those tiny dots
46:05on the top
46:05of your car's front window?
46:07The pattern
46:07of these little black dots
46:09minimizes distractions
46:10for your eyes.
46:11This black part,
46:12also known as frit,
46:14normally gets warmer
46:15than the clear parts,
46:16which prevents
46:17the windshield
46:18from deforming.
46:19And no,
46:20the tab under
46:21your rearview mirror
46:22is not made only
46:23for the purpose
46:23of hanging fluffy dice
46:25or aromatic-pleasing
46:26air fresheners.
46:27It's actually a switch
46:28that allows you
46:29to adjust the position
46:30of the mirror
46:31depending on
46:32the time of day.
46:33Flip it one way
46:34and it's the
46:34daytime driving mode.
46:36Flip the other
46:37and you're ready
46:37to drive safely
46:38during nighttime
46:39as it tones down
46:40the glare
46:41coming from headlights
46:42of the cars
46:42behind you.
46:44Next time you head
46:45out to the supermarket,
46:46make sure to keep
46:47this in mind.
46:48In case you don't
46:49have a coin
46:49to unlock
46:50these shopping carts,
46:51there is a well-kept
46:52secret that can
46:53help you out.
46:54If you have
46:55your house keys on you,
46:56check for a rounded
46:57key head.
46:58If you happen
46:59to find one,
46:59try using it
47:00to unlock the cart.
47:01It should fit
47:02perfectly in there,
47:04replacing the need
47:04to carry coins around.
47:06Because,
47:06if we're being honest,
47:07who still has them?
47:09Elevators.
47:10If you want to ride
47:11them on your terms
47:12and your terms only,
47:13make sure to try
47:14something out.
47:15Most elevators
47:16have a secret
47:17button combination
47:18you can use
47:19to skip all the
47:19other selected floors
47:20and go directly
47:21to the one
47:22of your choosing.
47:23This might work out,
47:25especially on those
47:26days when you've
47:26pressed 13.
47:27But you wanted
47:28to press 33.
47:30On most elevators,
47:31this works once you
47:32simultaneously press
47:33the closed door button
47:34together with your
47:35floor number.
47:36This should help you
47:37get to your floor
47:38without stopping.
47:39Some elevators require
47:41you to double-press
47:42the selected floor numbers,
47:43as double-pressing
47:44will often cancel
47:45the previously-made request.
47:47While other elevators
47:49require you to hold
47:50the open door button
47:51and then double-press
47:52the buttons of the
47:53floors you'd like
47:54to cancel.
47:55Now, to stay out
47:56of trouble,
47:56it's best not to
47:57cancel the floors
47:58of the other people
47:59in the elevator.
48:00They won't take it
48:01kindly.
48:02Also, keep in mind
48:03that there are
48:04elevators that might
48:05not have this function.
48:06Now, for honey lovers
48:07out there,
48:08go ahead and raise
48:09your hand.
48:09If your pot of
48:10golden honey is
48:11crystallized,
48:12know that it is
48:13actually a good sign.
48:16Crystallized honey
48:16means that it hasn't
48:17been pasteurized,
48:18which means better
48:19product quality.
48:21With a decrease
48:22in temperature,
48:23the natural ingredient
48:24of honey,
48:24also known as
48:25glucose,
48:26will make it
48:27crystallize.
48:28Now, try making
48:29the best of it.
48:30To add some texture
48:31to your oatmeal or toast,
48:32add a layer of
48:33crystallized honey
48:34and enjoy
48:35nature's sugar.
48:36And if you don't
48:37like crystallized honey,
48:38plop it in the
48:39microwave for a
48:40minute or two.
48:41Ah, winter and fall.
48:43You know what this
48:44means, right?
48:44Sweater weather.
48:46But there's nothing
48:47more annoying than
48:47wearing your beautiful
48:49wool sweater and
48:50itching yourself
48:51all the way through
48:52it.
48:52Actually, I can be
48:54more annoying than
48:54that, but let's talk
48:55about itchy sweaters.
48:57To keep this from
48:57happening again,
48:58here's the secret.
48:59Turn your sweater
49:01inside out and
49:02soak it in cold
49:03water.
49:03Add two or three
49:04tablespoons of
49:05vinegar and let it
49:06sit for a while.
49:07Then, drain the
49:08water.
49:09Now, while the
49:10sweater is still
49:11wet, massage a
49:12generous amount of
49:13hair conditioner into
49:14the fibers of the
49:15wool.
49:16After letting it soak
49:17in the hair conditioner
49:18for about 30 minutes,
49:19gently press the
49:20excess water out of
49:22the wool and leave
49:23it to dry flat on
49:24a towel.
49:25There you go!
49:26No more itchy
49:27sweater.
49:28Any fast food
49:29restaurant you go to
49:30will hand out small
49:31paper cups for
49:32customers to fill with
49:33their ketchup, mustard,
49:34or barbecue sauce.
49:36But if you're eating
49:37some chicken nuggets or
49:38trying to dip your
49:39burger into the cup,
49:40there's always that
49:41bit of sauce that
49:42seems impossible to
49:43reach.
49:44Next time, try
49:45unfolding the cup.
49:47It'll turn into a
49:48small paper plate, and
49:49this way, you'll get
49:50all the ketchup you
49:51poured in the first
49:52place.
49:54Padlocks used in
49:55outdoor environments
49:56should be clean and
49:57lubricated every three
49:58months.
49:59Regular lubrication
50:00will help prevent
50:01padlocks from freezing
50:03in cold weather
50:03conditions.
50:04Look for the tiny
50:05hole on the bottom
50:06of the lock.
50:07Then, pour oil into
50:08it, and there you
50:09go!
50:10It opens again!
50:12One thing we often
50:13neglect is a point in
50:15an ointment cap.
50:16These pointy surfaces
50:17were designed to help
50:18us break the tinfoil
50:19protection of the
50:20ointment tube.
50:21You just turn the cap
50:22over and break the
50:24ointment seal with its
50:25own cap, and there
50:26you go!
50:28After a long day of
50:29work, all you really
50:30need to do is a bubble
50:31bath.
50:32You turn on the hot
50:33water and let it run
50:34for a few minutes.
50:35You might even light a
50:36candle and pour some
50:37essential oils into
50:38the water.
50:39Then, in comes the
50:41liquid soap.
50:42You stir the water
50:43until the entire
50:44surface of the tub
50:45water is crammed with
50:46bubbles and make your
50:48way in.
50:48The bubbles in a
50:49bubble bath have a
50:50fundamental primary
50:51function.
50:52Their job is to
50:53preserve the water's
50:54temperature, just so
50:55you can have warm
50:57water for longer.
50:58Do you have sweaty
50:59feet?
51:00Weird question, I know.
51:01But if you're one of
51:02these people, here's
51:03some good news.
51:04All is not lost.
51:06Try putting a dry
51:07teabag inside your
51:09shoes and storing it
51:10in a dry place for a
51:11while.
51:12The teabags will
51:13absorb the humidity
51:14and the smell off the
51:15soles of your shoes.
51:17So, here I am
51:18thinking, shouldn't we
51:19have learned these
51:20things in school?
51:21Well, either way, if
51:22you learned something
51:23new today, make sure
51:24to tell us about it in
51:25the comments below.
