00:00Have you ever stopped to think about the thrilling secrets of day-to-day modern life on planet Earth?
00:07I'm talking about tiny windows and washing machines and little holes in airplane windows.
00:13If you haven't got a clue of what I'm talking about, tag along and allow yourself to be as surprised
00:19as I was when I found out.
00:23Remember the drawer at the bottom of your oven?
00:25Maybe you've been ignoring it all along, or using it to store pots and pans.
00:30Well, even though it can serve this function, that's not the only thing it's there for.
00:36The best way to use the bottom drawer is to keep your meal heated while you're waiting to serve it.
00:41Genius, right?
00:43Talking about secret doors, have you noticed that most washing machines have little flap doors at the bottom too?
00:50These doors actually serve as drain traps.
00:53It's where all the items that we put to wash together with our jeans and jackets go to.
00:59It's a type of collector, let's say, of small items.
01:03It stops them from getting into the main drain pipes and clogging them.
01:07It saves us hundreds of dollars in repairs each month.
01:12Now, who hasn't gone through the confusing task of having to measure how much pasta to cook for one serving?
01:19Well, here's the solution.
01:21The holes in the center of pasta spoons.
01:24They were actually made for measuring the exact amount of dry pasta you need for one serving.
01:30If you try stuffing wet cooked pasta through it, well, good luck with that.
01:36On a similar topic, have you ever wondered why pen caps have holes in them?
01:41Maybe you thought it was a design feature to regulate air pressure.
01:45But in reality, these holes have a much simpler and more important function – to reduce the risk of choking.
01:52Now, lots of people love to bite on their caps.
01:56And this tiny hole prevents them from choking in case they accidentally swallow a cap and it gets stuck in
02:02their throat.
02:03For kitchen lovers, there's a hidden secret right in front of your eyes that can change your life.
02:09Think pans.
02:11Now think handles.
02:12Right!
02:13They have holes in them.
02:14As it turns out, these holes were designed to hold the spoon you're using for cooking.
02:19And instead of dripping sauce all over the stove or your kitchen floor, you can place the spoon in the
02:26hole and let it drip the sauce directly back into the pan.
02:30Woo-hoo!
02:32Speaking of everyday items, and I was, most doorknobs are made of brass because this material makes them naturally germ
02:41-free.
02:41Unlike plastic ones, brass doorknobs are kind of magical.
02:45They can disinfect themselves without you having to clean them.
02:50Neat, right?
02:52Have you ever noticed that at the bottom of a measuring tape, there is a little dip?
02:57You can find it in that metallic part you need to pull on to measure something.
03:02Well, that dip is actually the exact size of a regular nail.
03:07It was designed for people to place the tape on top of a nail and use it as a support
03:12while they stretch the tape.
03:13And, well, I can't wait to try it out for myself.
03:17As for the margins in your notebook, they were invented to protect people's notes from mice.
03:24No, the mice weren't copying your answers for the math quiz.
03:28Actually, there were times when people had to cohabitate with rats and mice that often chewed on paper.
03:35So, to prevent information from getting completely lost, people created margins.
03:41This way, texts were moved closer to the middle of pages and remained unharmed by rodents.
03:48Hmm, perhaps this is where to digest information came from.
03:53And what about those tiny holes at the bottom of airplane windows?
03:58They have an extremely important function of regulating the air pressure inside the cabin.
04:04In other words, they help planes fly high up in the sky.
04:08Big responsibility, right?
04:11By the way, tray tables on an airplane are the germiest places inside the entire cabin.
04:18Studies showed that the trays had eight times the amount of germs on the toilet flush button.
04:25Now, how about we cut a commercial airplane in half and see what's inside?
04:31Well, it would look more or less like this.
04:34Rows of seats on top and everything else that needs to be stored at the bottom.
04:38I'm talking about passengers' luggage, emergency supplies, parts of the wing system, and so on.
04:46Moving on to bowling balls.
04:48Yes, I know it's a clumsy transition.
04:52Anyway, have you ever wondered what the insides of a bowling ball look like?
04:56If you have cut a professional ball in two, you'll see a familiar shape.
05:02Look closely.
05:03Do you see it?
05:04Doesn't that look like the logo of Brightside?
05:07Anyway, professional bowling balls are different from the ones in your local bowling alley.
05:12That's because they're designed to make fancy moves.
05:15They actually have some really complex engineering inside.
05:19They're shaped to help skilled professionals get more strikes.
05:23The weight of professional bowling balls is designed to be projected inward as they travel down the bowling lane.
05:29This makes it harder for them to get into the gutters on the sides of the lane.
05:35Speaking of balls, let's take a look inside a baseball.
05:39To make it light and aerodynamic, producers use several different layers.
05:44Starting from the core, we have a cork center enveloped by black rubber.
05:49Then there's a layer of red rubber, followed by two or three alternating layers of wool yarn.
05:56After that, there's a visible white leather cover and that beautiful red seam on the side, stitching it all together.
06:04And what if you had x-ray vision and managed to look inside a human bone?
06:10Ooh, spooky!
06:12I'd say what caused most attention is this spiderweb-like situation at the center of the bone.
06:18In reality, it's a highly condensed and complex structure of nerves that you have inside your bones.
06:25Aren't you lucky?
06:27Now, I've got a riddle for you.
06:29What is round can be found near the ocean and looks like an aerial view of the Guggenheim Museum in
06:35New York City,
06:36the one that's made almost entirely of ramps.
06:39If you said a nautilus shell, hey, then you guessed right.
06:44A nautilus is a shellfish whose house you can find in countless souvenir stores near the beach.
06:50It's made up of two layers, a matte white outer layer and an iridescent white inner layer.
06:56And if you were to cut it in half, it would look very similar to the insides of the Guggenheim
07:02Museum.
07:04Aloe leaves are good for healing purposes and also for hydration.
07:08But if you managed to look inside of an aloe leaf, the image you'd see would be satisfying and very
07:16relaxing.
07:16Who hasn't dreamed of a pool filled with jelly?
07:21Now, there seems to be nothing more mundane and regular than a tube of toothpaste.
07:27But you wouldn't think so if you cut open a tube that contains several colors.
07:32Now, there have been speculations that the insides of such a toothpaste tube might be divided by barriers so that
07:39the stripes don't mix.
07:41But if you cut it in half, you'll see that it has only one interior chamber.
07:47As it happens, there's a lot of science behind the making of striped toothpaste.
07:52According to a specialist, they have to ensure that the paste in all the stripes has the same physical properties.
07:59This way, the colors are naturally prevented from mixing with one another.
08:03That's why, if you tear a tube open, you'll see something that looks like several slices of pizza in different
08:09colors.
08:11If you open your closet, you're bound to find at least a few wooden hangers.
08:16Usually, they're made of cedar wood, which is a natural moth repellent.
08:20So, cedar hangers actually protect your clothes from moth infestation.
08:26For some people, more than others, eyeliner is an everyday must.
08:30Boy, isn't it.
08:31But did you know that back in ancient Egyptian times, both men and women used cool eyeliners to protect their
08:39eyes from the sun's glare?
08:41Way to go for the Egyptians for figuring that out!
08:45Now, if I could just learn to walk like one!
08:48Normally, we use headrests for the purpose of, well, resting our heads, right?
08:54Well, not only!
08:56As it turns out, headrests can be easily removed from the seats and used to break car windows in case
09:03of emergencies.
09:05Now, this one is a trick very few people know about.
09:09You probably place your doormat horizontally, like most of us do.
09:13But doormats serve the purpose of absorbing dirt from the soles of your shoes before you enter your home.
09:20So, for this function to work as it's meant to, the best way to place a doormat is vertically.
09:26This way, you take more steps on the top of the doormat before entering your house.
09:33And, last but not least, now, I don't want to be accusatory here, but you have probably been vacuuming your
09:40house the wrong way.
09:41And I can prove it.
09:43Most people just vacuum floors and carpets in one direction, or move the brush back and forth several times, thinking
09:50they've got all the dust out.
09:52But, according to cleaning professionals, the best way to vacuum is in rows.
09:57First, you go forward with the brush until you arrive at the end of the row.
10:02Then, you fluff the carpet up and move back down along the same row, gathering the dust that wasn't collected
10:09in the first sweep.
10:10Talk about efficient cleaning!
10:12On the other hand, my idea of house cleaning is to sweep the room with a glance.
10:18Hey, I don't want to disturb that protective layer of dust.
10:24If you've ever gotten bored while waiting in a car, like I have, you might have played around with a
10:29headrest.
10:30Yep, you can pull them off, and they'll come right off relatively easily.
10:34It seems useless at first, but that's something you'll want to do if you're ever trapped in a car and
10:40need to break a window to get out.
10:41Or, like I do, even a box of aluminum foil has its secret.
10:46On the side of the box, you can see a small tab you can push in.
10:50So simple, but that's what actually holds the roll of foil in place.
10:54This tab makes it way easier to unroll a sheet and tear it off without any frustration.
11:01Ever wondered why gripping a certain tool, handle, or even a pen kind of feels more secure when it's coated
11:07with a rubbery material?
11:09The keratin of the outer layer of the human skin is rough and stiff at a small scale.
11:14So, let's say you have a polished metal or glass, which is stiff, but also a smooth and impenetrable surface.
11:21When you encounter that, the actual contact area is small, as is the friction at the beginning.
11:27Your sweat pores secrete moisture, which is why the keratin gets hydrated and becomes softer.
11:33Because of that, it requires many seconds for the contact area to increase to the same value it reaches almost
11:40right away with some soft materials like rubber.
11:42However, this mechanism might be used by our tactile senses when we want to identify materials.
11:49Now, the pom-poms on beanies and other hats have their purpose.
11:53And it's not just to look cute and fluffy.
11:56Well, at least they did have a purpose.
11:58One of the theories says French sailors used to wear hats with pom-poms so they wouldn't hurt their heads
12:04on the ship when the weather got rough.
12:06Yep, the ceilings of the ship were really low.
12:08So, when the waves were too big, bang, you could easily hit your head on the ceiling.
12:13So, the pom-poms came in handy.
12:15Now, they're just a cute addition to our winter cats.
12:19That mysterious drawer under the oven, the one where you keep all your kitchen gear you just don't know where
12:25else to put?
12:25Well, you used it well in that case.
12:27But the drawer was originally designed for keeping your meals warm, at least until you're ready to serve them.
12:34And that space under your lower cabinets that protrudes slightly and can't be lifted?
12:39This area is also called a toe kick.
12:42It's the reason why you can stand closer to the counter while cooking.
12:46Also, the doors of the cabinets are off the ground, so they'll swing over your toes.
12:51The cabinet under the sink isn't for storage, either.
12:55Maybe that's where you keep your cleaning products, but its real purpose is to give you access if your sinks
13:01leak and you need to do some plumbing work.
13:04That weird little hole at the top of a lollipop stick you can see after finishing a candy is not
13:10a whistle.
13:11It has something to do with the manufacturing process.
13:14When pouring hot molten caramel into a mold, some of it will seep into this mysterious hole and harden.
13:21This way, the candy will stay on the stick and won't fall off.
13:26Keyboard letters aren't just randomly arranged the way they are.
13:29The first keyboard ever made belonged to the typewriter.
13:32Typists eventually got so good at their job, they started typing too quickly.
13:37So, the key arms would get cross-wired at some point and stuck.
13:42That's why manufacturers had to make the order of keys more random to intentionally slow down typists so they could
13:48keep the machine running.
13:50Do you like to let those brushes on the side of the escalators and malls polish your shoes?
13:56Believe it or not, that's not their main gig.
13:59The bristles are there for safety.
14:00People used to get their bags and clothes stuck in those escalators when they would stand too close to the
14:06sides.
14:07These nylon bristles kind of play with people's minds, and they keep their feet away from the escalator's skirt panels
14:13and avoid accidents.
14:15Most people assume bobby pins have curves for fashion, which is why they mostly place it in their hair with
14:21the wavy side up.
14:23But those little waves are actually there to catch the underlying bulk of hair and grip the pin into place.
14:29So, the wavy side should go down.
14:33You've probably noticed measuring tapes mostly come with a metal stub that ends with a small slot.
14:39If your hands are full of stuff, simply hang the slot on a nail for measurement.
14:43If you take a closer look, you'll see the stub is a little bit serrated on one side.
14:48This means you can use it to mark the points, so you don't even need a pencil.
14:53If you spend a lot of time in planes, you've probably noticed that little hole located at the bottom of
14:59the window.
15:00Nothing to be nervous about.
15:02It's what keeps us safe while flying high.
15:04It's something called a bleed hole.
15:06You can see right there in the middle of the pane of the three window panes that actually protect passengers
15:12from the outside pressure.
15:13This hole may be tiny, but it takes all that pressure off the outer one.
15:18The hole also gradually exposes it to cabin pressure, which helps with fixing pressure imbalances on the windows, if there
15:25are any.
15:27There's a number 57 staring at you from the middle of the Heinz ketchup bottle forever.
15:32According to the company, only 11% of people are aware the number really has nothing to do with the
15:38product label.
15:39It's actually a sweet spot, where you can tap to get the sauce onto the plate.
15:44So, next time you want some ketchup, there's no need to bang the bottom off.
15:48Just hit this spot.
15:51Grooves on the bottom of cups are there to make cleaning them in the dishwasher more convenient.
15:56When you place your cups upside down, these grooves will allow the water to flow rather than stagnate.
16:02This way, the water won't spill onto your feet when you take the cups out.
16:06The grooves are there to allow cool air to flow beneath the cup, too.
16:10They also keep cups from cracking when they heat up after you pour hot beverages in.
16:16You probably noticed that little dot next to the camera on an iPhone and probably thought it was a flash.
16:23Nope, not a flash, but a microphone in charge of catching sounds when you're using the back camera.
16:29Next time you're looking for a quick bite and decide for fries at McDonald's, check that bendable flap near the
16:36top of the box.
16:37Some like to bend it towards the fries.
16:40That way, you can cover your fries up and keep them warm.
16:42But if you're not that patient, you can flip the flap backward and basically turn it into a makeshift plate
16:49for your fries.
16:50Just bend it down firmly enough.
16:52You don't want it to spring back up and spread the sauce all over you.
16:55Take it from me, it's messy.
16:58In the 1970s, people didn't want toothpaste just to keep their mouths healthy, but also to freshen their breath.
17:06Aquafresh decided to answer that call, so they added a blue stripe to their product.
17:10Since consumers started paying more attention to their teeth and gums, the company added a third red stripe to their
17:16paste.
17:17The paste now has three functions – freshening, cleaning, and plaque control.
17:22And yes, solid white toothpaste can offer the same benefits, but brands continue to add stripes to their paste anyway.
17:30Speaking of toothpaste, do you know those colors on the bottom of tubes?
17:34The colors don't mean anything in particular.
17:36They're there to help in the manufacturing by telling light sensors where the end of the tube is.
17:42Thanks to it, the machine can cut and seal the tube properly.
17:46Hand sanitizers are commonplace nowadays, and you can apply them in many other ways besides just cleaning your hands.
17:53It also works great when you want to remove stains from your clothes.
17:57Sanitizer breaks up oily, greasy spillages and does a great job as a degreaser.
18:02You can even use it as a deodorant if you get caught out on a hot day.
18:07Did you ever notice that the toilet paper color is usually white?
18:11But this color wasn't always a favorite.
18:14In fact, colored toilet papers popped out on the shelves in the 1950s.
18:19Homeowners purchased pink, blue, yellow, green, and even black paper because these colors matched the interior.
18:27But eventually, many doctors began to associate the dye in colored toilet papers with increased health risks.
18:34Also, the dye didn't allow the colored paper to decompose as quickly when it was flushed down,
18:40which increased the risk of clogging septic tanks.
18:43This made manufacturing and retail prices too high compared to the basic white paper.
18:48And eventually, the demand began to fall.
18:53And now, let's take a closer look at these fancy patterns.
18:57Most people probably don't care about the decorations when it comes to their toilet paper.
19:02However, these patterns still exist.
19:05But why?
19:06Well, there are several opinions.
19:09Some say it's just a marketing tool.
19:12Manufacturers use pretty decor to make their products look more aesthetically pleasing
19:16and to make customers associate their brand with elegance and a luxurious lifestyle.
19:22Another explanation is more practical.
19:24These patterns fluff up the paper, which makes it more absorbent.
19:30Speaking of fluffiness, have you ever wondered why they have such rough toilet paper in public toilets?
19:36The most obvious answer is that high-quality toilet paper is more expensive.
19:41Also, companies prefer purchasing giant rolls of low-quality paper because they can change them less frequently.
19:48This decision also helps prevent stealing.
19:51Yes, people actually steal paper from public toilets.
19:56Have you ever noticed that light switches in public toilets are usually placed outside?
20:02Well, it's not a coincidence.
20:04Construction companies do it for safety reasons because, as we all know,
20:08electricity plus water is a dangerous combination.
20:11And light switches are connected to power.
20:14Therefore, electricity literally flows through them.
20:18Of course, professionally installed switches will have a bunch of additional safety precautions.
20:23But most builders prefer not to take risks.
20:26The UK has far stricter rules for light switch safety compared to the US.
20:31That's why, if you live in London, you'll probably find light switches outside the bathroom more commonly.
20:36But don't worry, most bathrooms in the US feature independent electrical circuits.
20:42This provides additional safety in case of accidental electric shock.
20:47When any change in the electrical current happens, they should shut off automatically.
20:54There are so many awesome lighting opportunities in this world.
20:58But why are the traffic lights red, green, and yellow?
21:02Turns out, there's a reasonable explanation for it.
21:06Before traffic lights for cars, there were traffic signals for trains.
21:10At first, railroad operators used white color to mean go, red to mean stop, and green to mean caution.
21:17But later, they realized that white wasn't such a good idea.
21:21Because bright white light could easily be mistaken for stars during the nighttime.
21:26So railway companies changed the white color for green to mean go, and yellow to mean caution.
21:31Because these colors are easily distinguishable from the others.
21:35And eventually, this tradition spread to traffic lights for cars, and became a standard.
21:41As for the red color, it has the longest wavelength, which means that drivers can see it from a greater
21:47distance than other colors.
21:48And the color yellow was chosen as a caution sign.
21:52Because it has a slightly shorter wavelength than red, but still longer than green.
21:59What's the dustiest room in your house?
22:02Usually, the answer is a bedroom.
22:04But why?
22:05Bedrooms tend to generate dust from skin cells, dust mites, and fibers from fabrics in your bedsheets, carpets, and curtains.
22:13If you have a pet, its fur and skin cells add a significant amount of dirt to this dusty party.
22:21Luckily, there are simple ways to make your bedroom less dusty.
22:24This includes making your bed every day, and cleaning the area regularly with both a vacuum cleaner and water.
22:31You can try to get rid of carpets, and unnecessary furniture and decor items that tend to collect dust.
22:38Also, pay attention to the quality when you buy curtains or bedsheets.
22:42The looser the fabric, the more dirt it collects.
22:46And finally, you can ban your pet from entering the bedroom.
22:49But let's be honest, you would never do that.
22:53Modern air purifiers, air conditioners, and ceiling fans can help make your sleeping area cozier.
22:59But make sure to clean them regularly.
23:01Otherwise, if your filter is dirty or clogged up with fur or any other pollutants, it won't collect new dust
23:07properly.
23:08And the dust would end up on your bedroom surfaces.
23:14Speaking of dust, did you know that you can clean the edge of a broom with a dustpan?
23:18This zigzag over here is not only for aesthetic purposes.
23:22You can use it as a comb for the bristles.
23:26Have you ever had these marks behind your ears after wearing your glasses?
23:31Sometimes it can even take them weeks to go away.
23:34Well, it's a sign that the side pieces of the glasses, called temples, are not adjusted properly for your head.
23:41In other words, they're too tight.
23:43This can cause skin irritation and even headaches.
23:47If they're bent towards the area behind your ears, they can press on the fragile part of the skull.
23:53So, keep in mind that temples should not only have the correct size, but also correct adjustment.
23:59A professional optician can easily fix this problem.
24:03It's way safer than trying to do it on your own.
24:07Box graters can be used in a horizontal position, too.
24:11In many cases, it's much more convenient to grate a carrot or a big block of cheese this way.
24:17If you want to grate a soft product like goat cheese or mozzarella, you can put them in the freezer
24:22for about 30 minutes before grating.
24:25Also, there's a way to make the cleanup easier and prevent the cheese from sticking.
24:30Spray the grater with a small amount of oil before using it.
24:34And now, let's take a look at the most unpopular sides of the box grater.
24:39Have you ever used them?
24:40This side is actually designed for slicing.
24:44It's pretty handy if you want to make thin vegetable slices for your salad or pasta.
24:49Or slice potato chips.
24:51And these tiny punched out holes are designed for zesting or very finely grating.
24:58Graters are pretty useful for the next non-food tip.
25:02If you're on a budget, you can purchase this super cheap laundry soap.
25:06Grate a small amount and throw it right into your washing machine instead of using the regular washing gel.
25:13Did you know that you can change which way the refrigerator door opens?
25:17There are hinges over here.
25:19If you attach them on the other side, the doors will swing the other way.
25:23But before trying to do any repairs by yourself, make sure to disconnect the power source.
25:28And read the instructions for your particular model of the fridge.
25:32Have you ever noticed that there's a shiny side and a dull side to tinfoil?
25:38Many people believe that it matters which side is used up or down because the shiny side would trap the
25:44heat better.
25:45But, in fact, it makes no difference at all.
25:48The manufacturing process makes the two sides look slightly different.
25:52But they both serve their purpose equally.
25:57Tinfoil can be used not only in the kitchen.
26:00Here's a little-known battery hack.
26:02Let's say you're out of AA batteries.
26:05No worries.
26:06Use a smaller AAA battery and a bit of tinfoil.
26:09Just insert it on one of the ends.
26:11This will work because both AA and AAA batteries carry the same amount of voltage.
26:18Did you know that Chinese takeout food containers unfold and turn into plates?
26:23All you have to do is just to disassemble it from the two sides.
26:27And gravity will do the rest.
26:29By the way, the old-school name for this type of paperboard container is an oyster pail.
26:35Because it was originally designed to hold oysters.
26:38Go check your box of aluminum foil.
26:41Does it have push-in tabs on the sides?
26:43They're there to keep the roll in place as you pull some foil out.
26:47Now flip a stapler upside down.
26:49See the metal plate on the bottom?
26:51You can turn it to get temporary staples.
26:54Ones whose pins are bent outward and are easier to take out.
26:57Speaking of flipping stuff, do it with a salt jar.
27:01Nah, you should have closed the lid first.
27:03Now you've got salt all over the place.
27:05Okay, now you've done it.
27:06Look at the bottom of the jar.
27:08See the ribs on it?
27:09If you take another jar, say with pepper in it, and rub the bottoms of the two jars against each
27:15other,
27:16the salt will pour out evenly without you having to shake it vigorously.
27:19Same works with pepper, too.
27:21It wasn't their original purpose.
27:23But you can use soda can tabs to hang hangers on other hangers.
27:28By the way, the hole in the tab is there to put straws through and keep them in place.
27:33Post-it notes are supposed to be peeled off from the side like you're turning the page in a book.
27:38Most of us tear them from the bottom, and that just creates a crease and makes the whole note less
27:43sticky.
27:44The hole in your spaghetti spoon helps you measure the perfect portion.
27:49It's just enough for one person.
27:51Multiply that by however many people you're serving.
27:54Or maybe you just like to pig out on pasta.
27:57Hey, I'm not judgmental.
27:59Does the audio jack in your headphones have one, two, or three stripes?
28:03One band means your headphones just play sound.
28:07Two means stereo sound.
28:09And three mean the headphones also have a microphone.
28:13To prevent water from boiling over, just lay a wooden spoon across the rim of the pot.
28:18It only works for a little while, though.
28:20If the spoon's surface gets heated up to boiling point, the bubbles will just foam up and around it.
28:25That's why metal spoons won't do.
28:28They heat up too quickly.
28:30Silica gel packets can absorb up to 50% of the humidity in a confined space.
28:35So use them around the house.
28:37Take one to the lid of a container of dry goods.
28:40Be it dog treats, breadcrumbs, cookies, you name it.
28:43Throw one in each of your dresser drawers.
28:45Just make sure they don't get accidentally eaten.
28:48Most people use bobby pins upside down.
28:51The zigzag part goes closer to your scalp.
28:53The texture keeps the hair and pin in place much better.
28:58Bubble wrap was originally created as wallpaper that would be easy to clean.
29:02But the decor idea didn't take off.
29:05So they found a new use for it.
29:07Now they help cushion items during shipping.
29:09And they pop so nicely, of course.
29:11Hey, just ask my dog.
29:13All crackers and some cookies have holes to make sure the final product has the right texture.
29:19These teeny tiny holes allow steam to escape, so your crackers and cookies wouldn't snap.
29:25If it weren't for these holes, also known as dockers, steam would build up inside the tree.
29:30And the final result might have been scrumptious, but it would have been rather oddly shaped.
29:36The scalloped edges on Ritz crackers are there so you can roll the cracker over your cheese,
29:41so that you get the perfect-sized piece to sit on top.
29:44It works for soft-dish cheese only.
29:47Don't try to cut some parmesan like this.
29:50Cheesily speaking, you probably grate your cheese with a cutting board or a plate underneath the box grater.
29:56Try a more convenient method.
29:58Flip the box grater and lie it on the side.
30:01This way, you get the finest shreds of cheese, and it's mess-free.
30:06PVA glue doesn't stick inside the bottle because it contains long molecules, such as polymers and water.
30:13Once you squeeze the glue out, the water trapped inside evaporates, leaving only sticky polymers.
30:20Super glue doesn't stick inside the bottle because of a special chemical that hardens when it hits water vapor.
30:26So, the glue doesn't stick because the container keeps water out.
30:29The bread goes stale just because it loses moisture.
30:33When you add water to the flour, it changes texture.
30:36And the starch molecules get pretty disorganized.
30:39Hey, I can relate.
30:40That's why bread is soft and fluffy when it's freshly made.
30:44But the more it cools down, the more water it loses.
30:47Starch molecules get their original crystallized state back.
30:51Also, recrystallization happens way faster in the fridge.
30:54The sole of your sneakers, and even the tires of your car, are just one huge molecule.
31:01It's because when rubber is vulcanized, all the molecules become connected through the sulfur.
31:06So, they turn into one, but a really large molecule.
31:10Your jeans are blue on the outside and white on the inside because of a smart way to weave the
31:16fabric.
31:16The warp thread is dyed, while the weft thread has no color.
31:20It's just white.
31:21This way, manufacturers reduce the amount of dye needed for each piece of clothing.
31:26By the way, most jeans are blue because they were originally dyed with indigo dye with a rich blue tint.
31:33This dye was picked for the way it interacted with cotton.
31:36When the cotton is heated, most dyes just penetrate it.
31:39But indigo dye stays attached to the surface.
31:42As a result, each time people wash their jeans, the dye molecules escape the fabric,
31:48leaving a unique pattern on each garment.
31:51Today, manufacturers use synthetic indigo dye.
31:55Bananas have thick skin to keep insects away.
31:58However, it gets thinner as the fruit ripens.
32:01Once the banana is ripe, it starts getting water from its skin.
32:05Birds and animals can also tear the thin skin easily.
32:08Hey, smart move, Mother Nature!
32:10The public toilets tend to be U-shaped for hygienic reasons.
32:14This way, anyone who wants to use it is less likely to get in contact with ceramic, normally swarming with
32:21germs.
32:22The bottled water has an expiration date.
32:25However, the water itself doesn't go bad.
32:28The problem is about the bottle.
32:30The plastic starts releasing chemicals over time, so the water gets contaminated.
32:34You can't drink it anymore.
32:37Glass-bottled water has an almost indefinite shelf life.
32:40Still, some criteria, as changes in room temperature, may lead to a slow increase of bacteria in water.
32:47So, it might go bad, too.
32:48If all else fails, try drinking it from the faucet.
32:52Who would have thought?
32:53Fresh water.
32:54In-flight food is way saltier and spicier than back on land.
32:59Airlines have to give an extra kick to all the dishes due to in-cabin conditions.
33:04The combination of dry air and changed pressure changes how we perceive taste.
33:10Also, the taste isn't only about taste buds.
33:12It's about 80% smell.
33:14But as odor receptors don't work the way they should because of dry cabin air,
33:19Well, without some extra seasoning, the food would have been almost completely tasteless.
33:24And yes, I've been known to be completely tasteless myself.
33:28Veins appear blue because they're under our skin, and skin scatters more blue light than red.
33:34Also, the skin around the veins looks even redder than the veins, enhancing the contrast,
33:39and the veins appear even bluer.
33:41However, it's just an illusion.
33:44Our blood is always red.
33:46Trust me.
33:47Supermarket tomatoes look tremendous, but taste bland because,
33:51for the past 70 years, farmers have opted for fruits that ripen more evenly
33:56and look better and more pleasing to customers.
33:59Wild tomatoes are dark green and don't ripen evenly.
34:03Still, the tomatoes the farmers grow have a teeny-tiny mutation in one gene.
34:08That's why they're evenly colored but can't produce chloroplast properly.
34:12It changes the whole photosynthesis process,
34:15leaving the evenly colored tomatoes with less sugar in their tissues.
34:20As a result, these tomatoes tend to taste like cardboard.
34:23The moral to the story appears to be,
34:25go get some ugly tomatoes.
34:28Or tomatoes.
34:29The space below, a cup of noodles, is there to protect the noodles during transport.
34:35This technique is called a middle suspension.
34:37This way, they're protected better in their styrofoam cup,
34:41and it also helps those noodles soften more evenly and quickly.
34:45Now, chewing gum wasn't invented for keeping your breath fresh.
34:48It was supposed to be a replacement for rubber.
34:51But the rubber experiment failed,
34:53giving opportunity to a modern version of chewing gum.
34:57Sandwiches have all their filling in between two slices of bread to keep the hands clean.
35:02Well, at least it was so when the first sandwich was invented.
35:05Some centuries ago, I wasn't around then,
35:08the fourth Earl of Sandwich, John Montague,
35:11asked his chef to cook him something yummy he could eat without interrupting his long binge.
35:16The chef, I think he was named pastrami or something,
35:20wrapped meat and all the other ingredients in the bread to make the dish greaseproof.
35:25And finally, all the ingredients in margarita pizza stand for one of the colors in the Italian flag.
35:31Basil represents the green stripe,
35:34mozzarella represents the white one,
35:36and tomatoes, or tomatoes, represent the red stripe.
35:39And if you want it tastier, use ugly tomatoes.
35:44Now, here's a trick.
35:45Instead of putting the box grater vertically on top of a plate,
35:48put it horizontally, with no plate underneath, of course.
35:52This way, you won't risk scraping your knuckles,
35:54because only your fingertips will eventually touch the grater when you reach the end of the process.
35:59Also, it gives the grater more stability,
36:02when otherwise, you'd have to balance the grater or even hold it in the air with the other hand.
36:06When you're done, or when there's just too much grated stuff on the bottom wall of the grater,
36:11simply turn it on its side to pour the contents into the bowl or plate.
36:16Flowers in a vase would stay fresher for longer if not for the bacteria that breed in the water.
36:21Since copper has some antibacterial properties,
36:25dropping a penny into the water will help keep the microbes at bay,
36:28and let you enjoy your flowers for that little bit longer.
36:31An easy way to check if your bed linen has dried completely
36:35is to put a small mirror in between the layers for about 5 minutes.
36:39If the mirror has steamed up when you pick it up,
36:42it means the sheets are still a bit damp.
36:44Let them dry until the mirror stops getting cloudy.
36:47A damp bed is a lovely breeding ground for fungi and bacteria.
36:52Okay, I'm in.
36:53If you have a not-very-healthy habit of eating in front of your computer,
36:59you'll be surprised at how much crumbs and grime there is inside your keyboard.
37:04Now, you can just turn it over and shake it vigorously, of course,
37:07but that's not very good for any piece of tech, you know.
37:10So instead, take a post-it note and run its sticky part over the keyboard.
37:15It will collect the little pieces of trash like magic.
37:18Even a better way to do it, though, is to take a slime and stick it to the keyboard.
37:23Then take it away, squeeze it, and stick again in another part.
37:27The slime will fill the entire space between the keys,
37:31and its sticky properties will let it gather every little bit of garbage.
37:35Separating egg yolks from whites is easier using a plastic bottle.
37:39Break the necessary number of eggs into a bowl,
37:42and then take an empty plastic bottle and squeeze it.
37:45Hold the bottle over the yolk and release.
37:47It'll pull in air and the yolk together, leaving the white in the bowl.
37:52Repeat with the rest of the yolks, and you're done!
37:55And that's no yolk!
37:57If you're tired of spitting out the stones when eating cherries
38:01or want to make a cherry pie, push the stones out with a straw.
38:05Also, many garlic presses have a special tool on their handle
38:08that can be used exactly for that.
38:11Cleaning a blender can be a nuisance if you do it manually.
38:14Instead, fill it with hot water and add some liquid soap or detergent,
38:18then run it for about 10 seconds.
38:20Rinse it afterwards, and it's clean.
38:23Plaster walls can crumble, flake, and spread dust all over the floor
38:27when you hammer nails into it.
38:29Cut a strip of masking tape and stick it to the place you want to hammer a nail in.
38:33The tape won't let the plaster crack and crumble, leaving the hole neat and clean.
38:39Small scratches and dents on wooden furniture can be removed with some toothpaste or a walnut.
38:45For toothpaste, rub a pea-sized amount of it into the scratch until it's gone,
38:50then wipe the leftovers with a damp cloth.
38:52For a walnut, take a half of that brain-shaped nut and rub it into the dent.
38:57Then rub the area with your fingers and buff it with a soft cloth.
39:02This'll help the wood absorb the oil from the nut, making the scratch sealed and gone.
39:07The sticky residue on jars left after you removed the stickers
39:11won't be easily removed by water and detergent.
39:14So take some vegetable oil instead.
39:17Soak a cotton pad in it and wipe the sticky surface.
39:20Let it sit for a while and then wash the oil away together with the residue.
39:25If you can't comfortably reach the wick of a candle with a lighter,
39:29hey, take a stick of spaghetti.
39:31Light up its end and you'll get a burning stick that's easy to use for hard-to-reach places.
39:36Now, next time your razor blade's getting dull,
39:39try rubbing it backwards on a pair of jeans for regular upkeep.
39:43Not while you're wearing them, of course.
39:45Make sure you keep the blades dry, too, or even kept in mineral oil.
39:49That'll stop them from rusting.
39:51Keep all those jelly, ketchup, peanut butter, and mayo fresher for longer in your fridge
39:56by turning the contents upside down.
39:59This creates a partial vacuum inside the container, helping prevent mold growth.
40:04Storing ice cream upside down will prevent freezer burn, too.
40:08To bring your permanent marker back to life,
40:11simply put a few drops of rubbing alcohol into the felt material inside and shake.
40:16Once the felt absorbs the rubbing alcohol for a couple of minutes,
40:20the marker will be almost as good as new.
40:23Now, don't keep throwing away lettuce that goes black too quickly.
40:27Covering it with a dry paper towel and then placing it in an airtight container
40:31will help it keep fresher for much longer.
40:34This goes for any leafy greens you've got leftovers of.
40:38That sharpish bit sticking out of the cap of your favorite cream is there for a reason.
40:43These tubes are usually sealed with foil,
40:45so unless you love breaking your nails trying to open them,
40:48just flip the cap over and push.
40:51Your bobby pins might not stay in place if the grooves aren't facing the right way.
40:56They should always be on the bottom, close to your head.
40:59Still coming loose?
41:00Well, put a squeeze of hairspray right onto the bobby pin before you put it in your hair.
41:05Now, your cotton rounds pack has those strings on it,
41:09so you can hang it on a handy hook in the bathroom.
41:11But there's no need to loosen and tighten it back up every time.
41:16Check out the bottom of the pack.
41:17It has a perforated line.
41:19Tear it open carefully, and you're good to go.
41:22Two zips too much?
41:24Maybe.
41:25But they come in handy as a clever anti-theft device.
41:28Just lock them together.
41:30Now, no one can open your backpack.
41:32Don't have a lock on you?
41:33You can also tie them together with some string, or even just a paper clip.
41:38Anything to slow those pickpockets down.
41:41That tiny little button on the back of a shirt collar is used to hold your tie in place.
41:46Hey, you don't want your tie trying to escape back there.
41:50Shoe manufacturers care about their customers.
41:53So, most running shoes now have a special anti-blister system pre-installed.
41:58Sounds intense, but it's basically just that extra hole on top of your sneakers.
42:02Make a loop with the extra hole, inserting the lace backward.
42:07Cross your laces and put them through the loops.
42:09Now, pull the laces down to lock your foot in place.
42:12Now, run.
42:13Yeah, go ahead.
42:15Car headrests are all about comfort, and detachable headrests are all about safety.
42:20If you pull the headrest out, you'll see two sturdy metal bars.
42:24If you ever get locked or trapped in your car, you can use the bars to smash the window and
42:30get out.
42:31If you've got some pesky parsley stuck in your teeth, try this tip.
42:35It can be hard to get it out with loose floss.
42:38You need more tension, so just tie it in a knot.
42:42It's not an accident that soy sauce bottles have two spouts.
42:46The sauce is liquid, and it flows out of the bottle pretty easily once you turn it over.
42:50Most Asian food lovers have spilled it at least once in a lifetime.
42:54That's why nowadays, restaurants prefer serving soy sauce in special bottles that have two
43:00spouts.
43:00This design allows you to control when and how much sauce will come out.
43:05Just put your finger on one spout when you pour the sauce through another.
43:09If you press your finger tightly to the spout, the sauce will stop flowing, and if you remove
43:14your finger, it'll flow again.
43:16And don't forget to ask your server, hey, wasabi!
43:21A hair straightener is an excellent tool, not only for treating your natural curls, but
43:26also for fixing crumpled money or documents.
43:29You can also use a regular iron for this purpose.
43:31Just make sure you don't turn on steaming mode, otherwise there's a risk of damaging
43:36the paper.
43:38Hair bands are good not only for getting your hair done, but also to open a glass jar with
43:43canned food.
43:43Your hands might slip on the tightly closed lid, and if you don't open the can from the
43:48first attempt, your palms tend to get sweaty, making the task virtually impossible.
43:54So, put a hair band on the lid to fix your hand and make your grasp stronger.
43:59A simple rubber band will do as well.
44:01Now, it's time to take my sweaty palms and go!
