00:00:00Why do some drinks taste way better when they're cold?
00:00:03The physical sensation you get when drinking sends the brain a message, you're rehydrating.
00:00:07This sensation is even more enhanced when the temperature of your drink is colder or hotter than your throat and
00:00:13mouth.
00:00:13You stimulate the nerves that are in charge of sensing temperature, plus the touch-sensitive nerves.
00:00:19The cold suppresses your sense of sweetness, so when you consume drinks from the store lukewarm, they might be too
00:00:25sweet to you.
00:00:27How come sloths are that slow?
00:00:29Their limited motions are mostly the result of their diet.
00:00:32They usually eat fruits, leaves, and buds.
00:00:35Since there's no proteins or fats in such food, these animals conserve energy by taking it slowly throughout life.
00:00:42An average sloth will travel or climb about 125 feet per day.
00:00:47When they're on land, it takes them almost a minute to move just one foot.
00:00:51Their digestive system also matches their slow movements.
00:00:55Sometimes, it takes up to a whole month for them to digest their meals.
00:00:58Their metabolic rate is 40 to 45% slower than in most other mammals to help them compensate for such
00:01:05a low calorie intake.
00:01:06That way, the sloth has little fuel to burn, which is why its movements are so chill.
00:01:12Like the majority of four-legged mammals, cats have five toes on their front paws.
00:01:17But there are only four toes on their back paws.
00:01:20One theory says that fewer toes on the back might help them run faster,
00:01:24and five front toes makes it easier for cats to climb trees, grab their prey, or slash.
00:01:31Why do fingernails grow slightly faster in hot weather?
00:01:34Some studies from the 1940s showed season, climate, and geographical location don't affect your fingernails' growth rate.
00:01:42But some other studies show they do grow a bit faster in the summer,
00:01:46and that's probably because of increased blood supply to your fingertips.
00:01:50Plus, during the holidays, you're probably chilling more,
00:01:52so you don't wear your nails away as quickly as when you do when you're constantly moving around.
00:01:58Why don't most of us like to hear the sound of our own voices?
00:02:02And it's not just the singing that's the problem.
00:02:04When you record your voice, it sounds higher pitched than you're used to hearing it.
00:02:08Usually when you hear your voice while speaking, it's conducted through the bones in your head,
00:02:12which is why it sounds deeper.
00:02:14Another reason why you don't like to hear yourself is that when you hear a recording of your own voice,
00:02:20you study it like other people's voices.
00:02:22And you're surprised because it seems like you're giving away a lot in terms of revealing your personality.
00:02:28How come bamboo grows so fast?
00:02:31It's the fastest growing plant on our planet.
00:02:33The Chinese moso bamboo can grow nearly three feet in just one day.
00:02:38You can find it in dense forests.
00:02:40There's hardly any light reaching the ground there,
00:02:42so bamboo has a pretty strong and urgent evolutionary pressure to grow tall and reach the sunlight as quickly as
00:02:49possible.
00:02:49There's also a kind of underground stem system where bamboo sprouts connect with their parent plant.
00:02:55This stem is the reason the sprout doesn't really need leaves of its own,
00:02:58at least not until it gets to its full height.
00:03:01Another reason bamboo grows so fast is that it gets taller with a constant diameter.
00:03:06Some other woody plants need a lot of energy on growing rings that thicken their stalks,
00:03:11but bamboo doesn't need it since it's just a single stick going straight up.
00:03:16Why do roads shimmer during hot weather?
00:03:19As the sun's rays beat down on the road, its surface becomes insanely hot.
00:03:23Because of higher temperatures, the layer of air above the road expands and becomes less dense.
00:03:29Because of this, light passes differently through the air from points further down the road,
00:03:33but this effect is not the same in all spots.
00:03:37The rising air is turbulent, so its density and optical effects are changing all the time,
00:03:42which is why you see that specific shimmering effect as you look down the road.
00:03:47Why do bottle caps have 21 spikes?
00:03:51Back in the 1880s, there were more and more carbonated soft drinks on the market,
00:03:55and people really liked them.
00:03:57But different types of bottle caps made of cork, metal, or porcelain were not tight enough,
00:04:03so beverages would lose their sparkles during transportation, and their quality would go down.
00:04:07To prevent this, one American inventor came up with a bottle cap called Crown Cork.
00:04:12It had a wavy edge with 24 serrations,
00:04:15and there was a liner inside to prevent liquid from contacting the metal plate.
00:04:20Eventually, people realized that 24 aliases made the bottle too tight and difficult to open,
00:04:25so they reduced it to 21, which pretty soon became an international standard.
00:04:30Why 21?
00:04:32First, 21 is a multiple of 3.
00:04:34The mechanical principle of physics says you need 3 points to support the object to be stable.
00:04:40It's hard to apply the 3-point rule with the round mouth of the bottle,
00:04:44so it's necessary to choose a number that's a multiple of 3.
00:04:47The second reason, when you incorrectly open a carbonated liquid,
00:04:51the pressure inside the bottle can be uneven,
00:04:53which can hurt you when you want to open your drink.
00:04:56With 21 spikes, it's safer for people to open the lid.
00:04:59And finally, 21 aliases guarantee the bottle cap is firmly fixed and carefully sealed.
00:05:05Why are humans so afraid of bugs?
00:05:08One theory says our ancestors simply had a better chance to survive if they were careful around the bugs.
00:05:14If you stick your head into a bee nest while trying to get honey,
00:05:17you might not live long enough to tell the story about how you did that,
00:05:21so you had to approach warily.
00:05:23Especially since there were so many bugs that were poisonous and dangerous to humans.
00:05:27So, over millions of years, our kind may have evolved a predisposition to feel uncomfortable
00:05:32when we're near spiders, bees, and other bugs.
00:05:36They're small, and they can avoid our stomps and swat while moving pretty fast.
00:05:40And I guess that contributes too.
00:05:43Why is Mars red?
00:05:44It's a rocky planet as old as the rest of our solar system,
00:05:48covered in mountains, volcanoes, many impact craters, and extremely long and deep canyons.
00:05:54But the red color of the fourth rock away from the sun
00:05:58is the result of the high level of iron oxide in the material its surface is made of.
00:06:04It's still a mystery why there's so much oxidized iron on Mars.
00:06:08Considering that the planet doesn't have an atmosphere or oxygen.
00:06:14Speaking of, Mars wasn't always without an atmosphere.
00:06:17A long, long time ago,
00:06:20it was a warm, wet planet with an atmosphere as thick as the one Earth has today.
00:06:26Now, it's just a dusty old place because of atmospheric erosion.
00:06:30It's a result of a process we know as sputtering.
00:06:34This happens because of ions carried by the solar wind.
00:06:38They knock atoms out of the atmosphere and catapult them into space.
00:06:43One more fun fact about Mars.
00:06:45The color of the sky up there is the opposite of the one you see on Earth.
00:06:49That means that up there, you'd see blue sunsets and sunrises,
00:06:53while the sky gets a reddish-pink color in the daytime.
00:06:56This unusual color during the day is there because of the vast amounts of dust
00:07:01that contains iron ore suspended in the atmosphere.
00:07:05Why does the moon change its shape?
00:07:08It goes through different phases each month.
00:07:10The new moon, the full moon, and then back again.
00:07:13The light coming from the sun only hits one of its halves at a time,
00:07:17which means it gives the moon a day side and a night side,
00:07:20just like we have on our planet.
00:07:22The shape we see on the Earth depends on where the moon is compared to the sun.
00:07:27If it's directly between the sun and our planet,
00:07:30the sunlight only falls on the side we can't see.
00:07:33In that case, we see a new moon.
00:07:36It appears dark in the sky.
00:07:38But when the moon is on the far side of our planet from the sun,
00:07:42it's a full moon because we're facing its day side.
00:07:45Once the moon is new, we'll be able to see a bigger part of its surface in the sky
00:07:51as it orbits our planet.
00:07:52We call it the first quarter moon when it's half full.
00:07:56When it grows in size but is not yet full, it's a gibbous moon.
00:08:01After the full moon, it shrinks,
00:08:03goes through different phases,
00:08:05and eventually returns to a new moon shape.
00:08:10Now, when you think about it,
00:08:12most bottles have one thing in common – long necks.
00:08:16Ever wondered why?
00:08:17Well, there are several reasons,
00:08:19none of which involve those other long necks –
00:08:22giraffes and ostriches.
00:08:24For starters,
00:08:25have you ever poured something into a glass from a wide jar?
00:08:29It can be real hard,
00:08:30since water often sticks to a wide surface
00:08:32and then spills around.
00:08:34The reason it happens is physics.
00:08:36Air and liquid tend to flow along a surface.
00:08:39This phenomenon is called the Coanda effect.
00:08:42It's hard to pour liquid because of this effect.
00:08:44The liquid molecules are drawn to the jar surface.
00:08:48Another reason is surface tension,
00:08:50which means that the molecules of a liquid
00:08:52tend to stick to one another rather than to the air.
00:08:55So, the water stays together and flows together down the surface
00:08:59instead of going where you want it to go.
00:09:01A narrow neck makes it easier to pour and drink from the bottle
00:09:05since there's a smaller surface for the liquid to spread around.
00:09:09Another reason is practical.
00:09:11A smaller neck requires less material to make it
00:09:13and a smaller cap to close it.
00:09:16This way, they can reduce the cost of the bottle.
00:09:19And one more reason.
00:09:20The necks prevent you from warming up the drink.
00:09:23If there's no neck,
00:09:24you'll most likely hold the bottle in the middle,
00:09:27right where the liquid is.
00:09:28The warmth from your hands will be rapidly warming up the drink inside.
00:09:33If there's a neck,
00:09:34you'll hold the bottle by the neck.
00:09:36It'll minimize the amount of heat transferred to the bottle
00:09:38and your drink will stay cold longer.
00:09:42If you use reusable bottles,
00:09:44you probably know that sometimes they smell.
00:09:47Even if you only use it for regular water,
00:09:49it still smells.
00:09:51But it's not the water that smells.
00:09:53It's the microorganisms in it.
00:09:55If you drink water from a bottle,
00:09:58the particles of your saliva and sweat stay in there.
00:10:01Those bacteria start to build up in the bottle,
00:10:03causing the smell.
00:10:05So if you choose reusable bottles,
00:10:07make sure to wash them every day
00:10:09to prevent those bacteria from building up.
00:10:12After washing,
00:10:13let it dry completely before using it again.
00:10:16Some people reuse plastic bottles,
00:10:18but it's not always safe
00:10:20because most of them are intended for single use.
00:10:23The main concern here is chemical leaching.
00:10:26The chemicals that are used to produce a plastic bottle
00:10:29can mix with the liquid.
00:10:30If you reuse a plastic bottle,
00:10:33wear and tear can create tiny,
00:10:34unnoticeable scratches inside the bottle
00:10:37where more bacteria can grow.
00:10:39So if you need a bottle to use for a while,
00:10:42invest in one that is made to be reused.
00:10:45But don't forget to wash it every day.
00:10:50Now, jeans first appeared in 1873.
00:10:54They were invented by Jacob Davis and Levi Strauss.
00:10:58Davis was a tailor who was producing covers and tents.
00:11:01And Strauss was a businessman who,
00:11:03among other things, was selling cloth.
00:11:06The first jeans were made by Davis from denim,
00:11:09the fabric he bought from Levi Strauss & Company.
00:11:12Together, they patented the design.
00:11:13Blue was a standard color for denim
00:11:16that was dyed using an indigo dye.
00:11:19The blue color is a tradition
00:11:20that still often followed today
00:11:22to replicate the original look of a pair of jeans.
00:11:26Jeans also have metal rivets,
00:11:28and they are there from the very beginning.
00:11:30Jacob Davis, the man who made the first pair of jeans,
00:11:33added copper rivets to spots
00:11:35where pants are more likely to rip,
00:11:37flies and pockets, to make them stronger.
00:11:40Today, they have more of a decorative purpose,
00:11:42since they are distinctive and traditional for jeans.
00:11:46Another special thing about jeans
00:11:48is those tiny pockets they have
00:11:50that seemingly serve no purpose.
00:11:52Well, maybe it's true now,
00:11:54but years ago,
00:11:55when many cowboys were wearing jeans,
00:11:58the pocket was made specifically
00:11:59to keep a pocket watch there.
00:12:01Also, back then,
00:12:03a pair of jeans had just four pockets,
00:12:05that tiny pocket, the watch pocket,
00:12:07two big pockets in front,
00:12:09and just one pocket on the back.
00:12:13Many zippers have the letters YKK engraved on them.
00:12:17It's an abbreviation that stands for the name of the company
00:12:20that can be translated as
00:12:22Yoshida Manufacturing Shareholding Company.
00:12:24This Japanese company is the largest zipper manufacturer in the world,
00:12:29so they put their initials on all the zippers they produce.
00:12:32That's around half of all the zippers in the world,
00:12:34and that's why you see their zippers more often than any other zippers.
00:12:41Now, zipping along,
00:12:43not only are the jeans blue,
00:12:44but the police officers' uniforms as well.
00:12:47The first official police officers
00:12:49appeared in the 19th century in London.
00:12:52They were given a blue uniform
00:12:54to contrast with the red and white uniform
00:12:56that military workers had already been wearing.
00:12:59Two decades afterward,
00:13:01the police force was adopted in the USA,
00:13:03and they follow the patterns.
00:13:05The uniform is still blue nowadays
00:13:07because it proved to be a good color.
00:13:09It's not that visible in dark hours,
00:13:11and police officers can observe things in people
00:13:14staying unnoticed.
00:13:16Also, stains aren't that visible on dark material.
00:13:19And, well, everyone knows that police officers wear blue
00:13:22and they're recognized by it.
00:13:24So, why change that?
00:13:27Those little white golf balls have dimples all over them.
00:13:31It turns out they aren't there just randomly.
00:13:33At first, golfers were playing with a smooth ball.
00:13:37With time, the ball would get all punched and damaged,
00:13:40but also, it would start to travel way further.
00:13:43The reason here is aerodynamics.
00:13:45Dimples allow the air to flow more smoothly
00:13:48around the ball, taking it further.
00:13:50So, the idea was adopted,
00:13:52and the balls got their dimples all around,
00:13:55allowing them to travel longer distances.
00:13:59Now, sometimes, when birds go somewhere far away across the ocean,
00:14:04they can spend days flying.
00:14:06Now, I've always wondered how they sleep on the way.
00:14:09Turns out, there are several ways.
00:14:11Some birds are always just half asleep.
00:14:14Half of their brain is working,
00:14:15and the other half is sleeping.
00:14:17Just like mine.
00:14:18Then they switch, and the other half sleeps.
00:14:21Other birds just take short naps throughout the day.
00:14:24And when I say short, I mean it.
00:14:26On average, a nap lasts around 9 seconds,
00:14:29and during that time, the bird is just coasting.
00:14:32Throughout the day, those naps add up,
00:14:34and a bird gets its sleeping time.
00:14:38Horseshoes are real shoes for horses.
00:14:41People attach them to their pets' hooves.
00:14:43They do it to protect the hooves
00:14:45in particularly tough and damaging environments,
00:14:48like tough pavements made of unnatural materials
00:14:50that horses aren't naturally adapted to.
00:14:53Horseshoes have their bizarre shape
00:14:55because they're nailed to the hoof.
00:14:57The center of a horse's hoof is sensitive,
00:14:59and they would feel the pain
00:15:01if someone tried to attach the horseshoe in the middle.
00:15:03But the sides of the hooves don't feel any pain.
00:15:06And for this reason,
00:15:07horseshoes are round and have an empty center,
00:15:10kind of like attaching fake-fashioned fingernails.
00:15:15Reading sometimes makes you doze off,
00:15:17and people who have trouble sleeping
00:15:19often take advantage of this
00:15:21and read in the evening to fall asleep.
00:15:23But if you don't want to fall asleep,
00:15:25why does it still happen?
00:15:27Well, usually, you read in a quiet and relaxing atmosphere,
00:15:30and also in bed or in a comfortable armchair
00:15:33wrapped up in blankets.
00:15:34This isn't only a perfect atmosphere for a read,
00:15:38but for falling asleep as well.
00:15:40Your mind stops wondering about all the troubles you had during the day,
00:15:44focusing on one thing.
00:15:46So it goes to the right mood,
00:15:48ideal for falling asleep,
00:15:50and so it does.
00:15:53Most shampoos say that you should wash your hair twice.
00:15:56But is it true,
00:15:58or is it just their way to make you use more of the product
00:16:00and buy it more often?
00:16:02Well, it depends on how often you wash your hair.
00:16:05Typically, the first wash removes all the dirt and dead cells,
00:16:09and the second wash moisturizes your hair and scalp.
00:16:12So yes, two times is a good thing to do,
00:16:15but only if you wash your hair once in several days.
00:16:19If you wash it every day, or every other day,
00:16:22there's not that much dirt accumulated there,
00:16:24and one wash is enough for you.
00:16:28Baby carrots are tiny,
00:16:30and unlike regular carrots, wet.
00:16:32Baby carrots aren't some special sort of carrots.
00:16:35They're actually made of regular carrots
00:16:37by cutting off the skin in outer layers,
00:16:39and then polishing them to look that pretty.
00:16:42The problem is, they can't retain moisture.
00:16:45A regular carrot retains some water inside
00:16:47because of the layers that lock it in.
00:16:50Once they're chopped out,
00:16:51baby carrots can dry out easily.
00:16:53So, they usually sell them in bags with some water inside.
00:16:58Toy stores are filled with Beanie Babies plush toys.
00:17:02And a detail that is even more iconic than their huge eyes
00:17:05is their tag saying tie.
00:17:08That's a small manufacturing company
00:17:10not many people have heard of.
00:17:12Beanie Babies appeared in 1993,
00:17:14and they went insanely popular.
00:17:16Tie is the name of the company,
00:17:19but it's not an abbreviation.
00:17:20It's the actual name of the company's founder,
00:17:24H. Tie Warner.
00:17:27Leaving your valuables or a chocolate bar in a car
00:17:30is a no-brainer.
00:17:31But there are other things people often overlook.
00:17:35Here's what to watch out for before leaving your car.
00:17:38Number one is aerosol cans.
00:17:41Hairspray, deodorant, spray paint, household cleaner, and that sort.
00:17:45On the back of these cans,
00:17:47you might notice a storage temperature recommendation.
00:17:49Well, stick to that.
00:17:52Here's what can happen.
00:17:53Since these cans are pressurized,
00:17:55they become more sensitive to temperature.
00:17:58What's inside the aerosol may expand,
00:18:00and this may result in a crack.
00:18:02And then, the can can blow up.
00:18:05Temperatures above 100 degrees Fahrenheit
00:18:07are already alarming,
00:18:08and it can easily get as hot as that in your car
00:18:11on a warm summer day.
00:18:14Researchers from the USA have figured out
00:18:16how long it takes a car
00:18:17to turn into a sweat factory on a hot day.
00:18:23Within one hour,
00:18:25the insides of the car parked in the sun
00:18:27reaches 95 degrees Fahrenheit or hotter,
00:18:30with an average temperature of 116 degrees Fahrenheit.
00:18:34So, if you want your car in one piece and running,
00:18:37take aerosol cans with you.
00:18:41The second item is sunscreen.
00:18:45Sunscreen is vital for your skin
00:18:47since it decreases the risk of skin complications
00:18:49and prevents skin aging caused by the sun.
00:18:53This includes wrinkles,
00:18:54sagging, and age spots.
00:18:57But when you leave sunscreen in your car,
00:18:59it gets exposed to high temperatures,
00:19:01and it can ultimately shorten its shelf life.
00:19:04If you end up finding spoiled sunscreen,
00:19:06you might notice a funny smell when you open the cap.
00:19:09Plus, the heat might cause the cap to open,
00:19:12and the sticky substance will get all over the car.
00:19:15The same rule applies to lipsticks
00:19:17and other cosmetics as well.
00:19:20The next one is plastic bottles.
00:19:24There are two reasons why you shouldn't leave them inside your car.
00:19:28Firstly, a plastic water bottle can act as a lens,
00:19:32magnifying the sun's rays and starting a fire.
00:19:34A fire department in Oklahoma conducted an experiment
00:19:38and confirmed that the danger of fire was real.
00:19:42David Richardson from that department says it can happen if the beam of light is focused enough.
00:19:47The second reason is related to your health.
00:19:51Many plastic bottles contain bisphenol, a potentially toxic compound.
00:19:55The BPA levels can increase at high temperatures, and that can be harmful to your body.
00:20:00There's a chance that this chemical can get into your drink after you leave the bottle inside the vehicle.
00:20:08Oh, and batteries!
00:20:09They could lose their capacity to work at full power when they're left abandoned in the car.
00:20:14You can buy a new pair and fix this problem,
00:20:17but it won't be as easy to solve the problem of leakage or a rupture.
00:20:21It can be bad for your health because battery acid is dangerous when inhaled and highly corrosive.
00:20:28The reason for leakage is, again, related to high temperatures.
00:20:32Battery manufacturers recommend keeping their products at room temperature.
00:20:38This fact is partially related to batteries.
00:20:41It's about electronics.
00:20:42Have you ever realized how hot your phone can get when it's exposed to the sun?
00:20:47You're driving, and let's say, looking at the GPS on your phone.
00:20:51Even in this situation, your phone can heat up.
00:20:54What will happen to it after hours of sun exposure?
00:20:58Phone companies are strongly against customers leaving their devices in vehicles
00:21:02because they might shut down, get damaged, or, you know, BOOM!
00:21:08Personal belongings are another priority on the list.
00:21:11A wallet or a handbag may come to one's mind first.
00:21:15Yet, a passport or even some change you leave near the passenger seat is sometimes enough to attract a thief.
00:21:22Better to keep such stuff out of sight, for example, by storing it in the trunk instead of leaving it
00:21:28in the back seat.
00:21:31Number 7 is also related to theft.
00:21:34Life can be too hectic sometimes, and it's understandable if you can't clean your car frequently.
00:21:39But leaving garbage in the car is another mistake.
00:21:42Thieves tend to search for messy-looking cars.
00:21:45They think that the owner doesn't use such a vehicle frequently.
00:21:50How about plants?
00:21:53I know it isn't that common to keep plants in the car on a daily basis, but sometimes you need
00:21:59to move them.
00:21:59The heat inside the vehicle can easily dehydrate the poor thing.
00:22:05Medications are another thing you shouldn't keep in the car for too long.
00:22:09The constantly changing temperatures inside the vehicle can decrease the effectiveness of your pills.
00:22:15Authorities recommend keeping most medications at 59 to 77 degrees Fahrenheit in a cool and dry place.
00:22:24Important documents that contain your personal data shouldn't be left in the vehicle either.
00:22:29Some examples of such documents are tax forms, financial statements, and school transcripts.
00:22:35A thief could commit fraud or identity theft using this valuable information.
00:22:42And there's also food and drinks.
00:22:44Experts recommend not leaving groceries or leftovers in a warm car for more than two hours,
00:22:50or only an hour when it's over 90 degrees Fahrenheit.
00:22:53The same rule applies in the winter, too.
00:22:57Canned foods, for example, have a high risk of going bad if a can of sweet peas, let's say, gets
00:23:03frozen in the car.
00:23:04The effect will be similar to what would happen to soda.
00:23:07Let it thaw in the refrigerator instead of leaving it at room temperature.
00:23:12If the product doesn't look or smell normal, throw it away in a place where not even an animal can
00:23:17find it.
00:23:18Don't try to taste it.
00:23:19Just trust your senses.
00:23:21If the item seems rusted or there are some cracks in the can, it should end up in the trash,
00:23:27too.
00:23:28Eggs are another example.
00:23:30Normally, eggs shouldn't be frozen.
00:23:32But let's suppose you forgot one grocery bag in the trunk of the car,
00:23:35and the weather was so cold at night that the eggs got frozen.
00:23:39Keep the eggs in the refrigerator before use.
00:23:41They should be hard-cooked.
00:23:43It's your only option.
00:23:44You see, freezing causes the yolk to become thick and syrup-like.
00:23:48It loses that natural flow and doesn't mix well with other ingredients.
00:23:55You shouldn't leave your pets alone in the car, obviously, and not just because of a potential rise in temperature.
00:24:01They will feel uncomfortable without you, their best friend, accompanying them.
00:24:06In their frustration, they might do something to get noticed, which can be, for example, ruining the interior of the
00:24:13vehicle.
00:24:15Now let's return to the winter season again.
00:24:17If possible, keep the gas tank of your car over half full.
00:24:21This can prevent the fuel lines from freezing.
00:24:23It also makes it easier to start the engine and hit the road in the morning.
00:24:27While keeping an eye on the fuel bar, it might be a good idea to glance at the tire pressure,
00:24:32too.
00:24:33The cold can result in tire pressure drops.
00:24:38Not only high, but also low temperatures can damage some items.
00:24:42A good example is paint cans.
00:24:45They should be quickly taken out of the vehicle in the winter.
00:24:48The ingredients in the paint can experience expansion, separation, and clumping due to the cold.
00:24:54In other words, you won't be able to use this paint anymore.
00:24:59Weather also affects wooden musical instruments, like violins or guitars.
00:25:04Changes in temperature and humidity can cause wooden instruments to warp, crack, or split.
00:25:11Glasses get affected by fluctuating temperatures, too.
00:25:15In a hot car, plastic frames can bend.
00:25:18Or plastic can become brittle when it's very cold.
00:25:21This makes glasses prone to breaking.
00:25:24Don't leave house keys and garage door openers inside the car.
00:25:28This is an everyday practice for many people, but it's risky.
00:25:31They can get into the wrong hands.
00:25:35To listen to music, most people connect their phones to the car or listen to the radio.
00:25:41CDs are getting less and less used these days.
00:25:43But don't leave them in the car anyway.
00:25:45They might get warped, and you won't be able to use them anymore.
00:25:49Can you think of any other items you shouldn't leave in the car?
00:25:54It's not an accident that soy sauce bottles have two spouts.
00:25:58The sauce is liquid and it flows out of the bottle pretty quickly once you turn it over.
00:26:02Most Asian food lovers have spilled it at least once in a lifetime.
00:26:06That's why nowadays, restaurants prefer serving soy sauce in special bottles that have two spouts.
00:26:12This design allows you to control when and how much sauce will come out.
00:26:16Just put your finger on one spout when you pour the sauce through another.
00:26:19If you press your finger tightly to the spout, the sauce will stop flowing, and if you remove
00:26:25your finger, it will flow again.
00:26:27Oh, nuts!
00:26:28Not all pistachios are easy to get.
00:26:31Therefore, people have come up with many devices and life hacks to split the hard peel.
00:26:35But what if you don't have any useful tools around you?
00:26:39Well, try to open a pistachio with another pistachio.
00:26:43These little candles in metal cups are called tea lights for a reason.
00:26:47Japanese tea houses initially use them for keeping the tea warm during traditional tea
00:26:52ceremonies.
00:26:52And today, you don't need any special equipment to do the same thing at home.
00:26:57Put the candle in a bowl and place your kettle on top of the bowl.
00:27:01The diameter of the bowl should be narrower than the bottom of your kettle.
00:27:04You can use the same technique to keep your food warm and even surprise your guests with
00:27:09delicious fondue.
00:27:11I am fond of fondue.
00:27:13How about you?
00:27:14Don't rush to throw away the metal cups and wick holders.
00:27:18You can reuse them.
00:27:19Take a wick out of a regular candle and cut it into pieces of suitable length.
00:27:23Put the pieces inside the wick holders.
00:27:26Then melt the wax and pour it into the cups.
00:27:28You can add essential oils and crumble wax crayons inside the wax to make your own unique
00:27:34and fragrant handmade candles.
00:27:37Metal candle cup is also a great tool to cut cookie dough into small circles.
00:27:42If you wear baseball caps, you probably wondered why they have these eyelets on the back.
00:27:48These small holes in each of the six crowns of the cap provide ventilation to your head.
00:27:53Also, if the size of the cap is too large, you can regulate it.
00:27:57Insert a lace into the eyelets and tighten them.
00:28:00It may look a little weird, but at least the cap won't fly away in the wind.
00:28:05A hair straightener is an excellent tool for not only treating your natural curls,
00:28:10but also for fixing crumpled money or documents.
00:28:13You can also use a regular iron for this purpose.
00:28:16Just make sure you don't turn on steaming mode.
00:28:19Otherwise, there's a risk of damaging the paper.
00:28:22Back to food.
00:28:23When your long-awaited yummy pizza finally arrives, don't rush to throw away the box.
00:28:29Tear the lid off along the fold line and divide it into four squares.
00:28:33Perfect disposable plates for pizza slices.
00:28:36Very handy when you eat outdoors or just don't want to wash the dishes.
00:28:41Well-known American bakery products such as bagels and donuts usually have one similar feature – a hole in the
00:28:48middle.
00:28:48The reason behind this phenomenon is more practical than aesthetic.
00:28:53When bakery manufacturers just started to cook donuts, they faced a problem.
00:28:57Donuts refused to bake evenly.
00:29:00The dough remained moist in the middle, while the edges got dry and crispy.
00:29:04So the manufacturers decided to leave holes in the middle of the buns, and it helped.
00:29:10If your washing machine breaks down, it may still serve you well.
00:29:14Pull out the drum and make a stylish brazier for your barbecue parties.
00:29:19Tea bags that we use today exist thanks to people's ignorance.
00:29:24No one knows exactly who invented them first, though.
00:29:27But one of the most popular legends says that American tea importer Thomas Sullivan offered samples of his tea packed
00:29:34in small silk pouches around a century ago.
00:29:37It was an easy and convenient way to organize tea tastings for potential wholesale buyers.
00:29:43But the customers took that too literally and began to brew tea by dipping the silk pouches directly into boiled
00:29:49water.
00:29:50And eventually, this brand new way of brewing became very popular.
00:29:55Clear nail polish has many areas of use.
00:29:58You can seal an envelope, protect iron cans in your bathroom from rust, apply it on fabric or lace to
00:30:05keep them from unraveling, and even repair home items.
00:30:09If you've scratched any wood furniture or floors, nail supplies can help to avoid splinters and damaging the wood with
00:30:15water splashes.
00:30:16Rub the scratch with a nail file, apply clear nail polish, and wait until it dries and hardens.
00:30:24If your tights are torn, apply nail polish around the entire snag or hole.
00:30:29When the polish hardens, turn the tights inside out and repeat the same process.
00:30:34Doing this will prevent the hole from widening.
00:30:38Having a bunch of similar keys may confuse anyone.
00:30:40You can paint them in different colors using nail polish and save your time.
00:30:47Multicolored bristles on your toothbrush serve a practical purpose.
00:30:50When the color fades, consider it as a sign that it's time to change the brush.
00:30:55Acrylic and oil paints usually come in metal tubes.
00:30:58If you want to paint a masterpiece but struggle to open the tubes properly, take the plastic lid off and
00:31:04turn it over.
00:31:05There's a special tip inside the lid.
00:31:08It will help to pierce the protective metal layer.
00:31:11Just make sure you don't press too hard on the tube.
00:31:13Otherwise, the paint will squirt out unexpectedly.
00:31:17Whoops!
00:31:18Chopsticks are one of the most multifunctional inventions in the world.
00:31:22For example, you can use them to support indoor plants.
00:31:25Place one stick inside the soil vertically next to the plant and fix them together with a string.
00:31:32The chopstick is also a handy tool when you try to pour essential oil from one bottle to another,
00:31:37especially when the bottleneck is small.
00:31:40Grab a chopstick, put it vertically, and pour the oil slowly onto the chopstick.
00:31:44It will help to direct the oil into the bottle and avoid spilling it all over the place.
00:31:50Furthermore, when you need to remove pits from cherries or any other berries,
00:31:55chopsticks can help as well.
00:31:56Place the end of the stick in the center of the cherry, push, and pop out the pit.
00:32:01To make this even more convenient, place the cherry on the neck of a bottle.
00:32:06Also, don't rush to throw away disposable chopsticks.
00:32:10When you collect enough sticks, you can create handmade interior decorations.
00:32:14A mirror frame in the shape of a sign, a picture frame, or a wooden lattice for photo collages, to
00:32:21name a few.
00:32:21Just stick the chopsticks together with a glue gun and paint them in your favorite color.
00:32:27Speaking of interior design, and I was,
00:32:30dominoes can be used to make a stylish handmade wall clock.
00:32:34Put the 12 figures in a circle and stick them up instead of the corresponding numbers.
00:32:40Modern standard forks have four tines, not only because it's the most convenient and practical choice.
00:32:46One of the popular explanations claims that people had initially associated forks with a human palm.
00:32:52And tines symbolize the four fingers, except for the thumb.
00:32:58Lemons are good not only for lemonade, but for your feet, too.
00:33:02It can help to soften the skin on your heels.
00:33:04Cut the lemon into two halves, squeeze out the juice, and apply the peel on your heels.
00:33:09Then put socks over the peel and wait for 30 minutes.
00:33:13Remove the lemon halves, wipe the heels, and apply moisturizer.
00:33:17Hey, your feet are soft and beautiful!
00:33:20Hair bands are good not only for getting your hair done, but also to open a glass jar with canned
00:33:26food.
00:33:28Modern market offers a variety of travel kits for males and females in all shapes and sizes.
00:33:33But there's an easier way!
00:33:35Surprise!
00:33:36A towel can serve not only as a towel, but also as a handy organizer.
00:33:41Lay a small face towel down on a flat surface and roll up one-third.
00:33:46Then draw vertical lines with the fabric to create pockets.
00:33:49Put all your toiletries inside the pockets and roll the towel.
00:33:54An eraser is a great tool when you need to remove small dark scuffs and traces from different surfaces in
00:34:00your house.
00:34:02And if your habit is to lose your earrings all the time, an eraser will help to deal with this
00:34:08issue.
00:34:08Just pin the earrings into the eraser when you don't wear them.
00:34:11You can use the same technique to keep needles and pins.
00:34:16Shiny shoes often have scratches and scuffs.
00:34:19Use an eraser to remove these imperfections and then wipe off the shoes.
00:34:23As per suede boots, an eraser can help to remove imperfections and dust.
00:34:28Just make sure that you rub your shoes gently and the eraser is soft and dry because suede is a
00:34:33rather fragile material.
00:34:36Use tape to make a fly trap.
00:34:38Hang a long piece of tape in the kitchen or by the window.
00:34:42The flies will stick to the tape.
00:34:44Stick pieces of tape on the legs of chairs that you often move across the floor.
00:34:49Doing so will protect your floor from scratches.
00:34:52If you're purchasing a special triangle cake knife, take two.
00:34:56Cutting and pulling out a piece of cake with two knives is way easier.
00:35:01Just squeeze both sides of the piece vertically and put it in a separate place.
00:35:05This way, the risk of damaging the cake is lower.
00:35:14There are some inventions that make us say, dude, why didn't I come up with this?
00:35:20And then you have the next question.
00:35:22Why don't we have it in my hometown yet?
00:35:24I'm talking about things like splash-proof toilets, liquid trees, and skyscrapers with slides.
00:35:32Yep, they're all pretty real, and you're about to fall in love with them.
00:35:37Have you ever used a public bathroom in the summer in your shorts and sandals and got splashed?
00:35:44It happens to the best of us, so no worries.
00:35:47If only there was some solution to this problem.
00:35:49Perhaps a urinal with a small hole so no liquid goes where it shouldn't.
00:35:54Looks pretty yucky and painful to me.
00:35:57An assistant professor at the University of Waterloo, Zhao Penn, and his colleagues came
00:36:03up with a way better solution for this sensitive issue.
00:36:07Their designs were inspired by physics and dogs.
00:36:10When a stream of liquid moves on a solid surface at a shallow angle, the splash is reduced,
00:36:16and the smaller the angle, the fewer splashes you'll see.
00:36:19You can even minimize them to a zero.
00:36:22And when dogs do their business, they lift their hind legs and do it on the vertical surface
00:36:27of a tree or a wall.
00:36:29I don't know if they actually care about it, but this does reduce the splash.
00:36:33Good job, Pluto!
00:36:35The team invented several models and presented them at the American Physical Society conference,
00:36:40and it was a hit.
00:36:42The inventors say that all of the models are no splash, but their favorites are the slice
00:36:48of apple, and the one that looks like a tall and slender J with a narrow and long opening.
00:36:53The new urinals aren't just super cool, but also more sustainable.
00:36:58You won't have to wash the floor with water, chemicals, and human energy after every use,
00:37:03which is a win-win.
00:37:06Here's another innovative public toilet idea for you, this time from Japan.
00:37:11They have completely transparent walls, which means, yes, you can see everything that's
00:37:17going on inside, from the toilet itself to the hand wash sink.
00:37:21It sounds pretty creepy, but the idea was actually to create a safe restroom in the park.
00:37:27Visitors can see if there's someone hiding inside before entering, and also check if the
00:37:32toilet is clean before entering.
00:37:34When you go inside and lock the door, the walls change color to opaque, and no one will be able
00:37:40to see you.
00:37:41They used glass covered with PD-LC film to make the walls, which allowed them to go from
00:37:47being transparent to safely in tents using electricity.
00:37:51Alright, now you've nearly convinced me to try one of those magical toilets.
00:37:55Oh, and they also double as excellent lanterns in the dark, shining bright in different colors.
00:38:01Bring a couple to my local park, I don't mind.
00:38:05Take a deep breath.
00:38:06If you don't like what you're breathing in, do something about it.
00:38:10That must have been exactly what the smart guys at the University of Belgrade, Serbia thought
00:38:14and invented the liquid tree.
00:38:17The liquid tree, not the pun and laugh a bit, consists of a glass tank filled with over
00:38:23150 gallons of water, some microalgae, and a solar panel, which provides electricity to
00:38:29a small pump.
00:38:31The microalgae need heating, so just in case there's no sun and the temperatures drop, the
00:38:36photo-bioreactor is also connected to the city grid.
00:38:40Microalgae work hard to do some photosynthesis magic and convert water and CO2 into oxygen,
00:38:46and then it goes into the atmosphere.
00:38:49The liquid tree also comes with a bench to sit on and enjoy its work.
00:38:54The liquid tree needs more work than a regular tree in the park.
00:38:57They need to replace the water and microalgae almost completely every month and a half.
00:39:03And they also need to take out the biomass that is the byproduct of the process, and let's
00:39:08admit, nothing can replace those blooming babes in spring.
00:39:12If you ever find yourself casually wandering in the forests of Estonia, don't freak out
00:39:17if you see some giant megaphones.
00:39:19These wooden, acoustic giants were set three hours away from the country's capital by interior
00:39:26architecture students.
00:39:27That's way cooler than the hamster roller coaster I once built for a science fair, I
00:39:32have to admit.
00:39:33More than half of Estonia is covered by woods, and they're pretty proud of this natural wealth.
00:39:38So it's not the first art project of this kind, and there was a winding, elevated pathway
00:39:43and a faceted woodland cabin.
00:39:46The idea of the megaphones is to crank up the natural sounds of a forest and also to
00:39:52serve as a rest spot for hikers.
00:39:55These wooden beauties are large enough to host several people.
00:39:59And hey, if you walk this far into the woodland, you'll be thankful for this.
00:40:04The students were given a task to invent some concepts of a forest library.
00:40:09They built the megaphones off-site and brought them to their permanent spots.
00:40:13They're set in such a way that sounds from three directions meet in the center and create
00:40:19a cool, natural surround sound effect.
00:40:22Have you ever helped your friends move into a new apartment in a building without an elevator?
00:40:27Then you're gonna love this one.
00:40:29Houses in Amsterdam have hooks on top.
00:40:32This is a medieval invention for pulling stuff up the houses.
00:40:35The simple tech consisting of a wheel and a rope still functions now, centuries later.
00:40:40Why not just use the stairs?
00:40:43Well, if you get inside one of those narrow Amsterdam buildings, you'll see there's hardly
00:40:48enough room to comfortably ascend, and you can forget about even trying to pull a table on top.
00:40:54Back in the medieval ages, pretty much like now, only rich people could afford housing around
00:41:00the canals in the best parts of the city.
00:41:02Those people were mostly traders and used the canals for their business.
00:41:07They stored goods in the same houses they lived in, and with regular floods, they had to find
00:41:12a way to keep the goods dry.
00:41:14And that's why they needed to invent something to lift furniture, goods, boxes, instruments,
00:41:21and food on the upper floors, and pull it in through fully open, wide windows.
00:41:27The lifting tech is one of the reasons the houses in Amsterdam are leaning forward.
00:41:31This position helped keep both the lifted stuff and the walls and windows safe during transportation.
00:41:38They didn't have to touch each other.
00:41:41The gables also assisted in the process and had to be made firm to withstand all the heavy
00:41:47weight.
00:41:47And in case you're wondering what gables are, they're sections of wall between the edges
00:41:53of a dual-pitched roof, typical for Amsterdam.
00:41:57Folks who live or work in skyscrapers have the opposite problem.
00:42:01Getting out of the building can take a while as you wait in line for the elevator.
00:42:05A slide going from the top of a skyscraper could be a solution.
00:42:09In 2016, they added one outside of the U.S. Bank Tower in Los Angeles at the height of 1
00:42:16,000
00:42:16feet.
00:42:17The see-through slide, made of glass just one inch thick, was built to withstand hurricane-force
00:42:22winds and earthquakes.
00:42:24It was built to bring tourists to the building, though not for the convenience of office workers.
00:42:30And then they decided it wasn't such a great idea, so the slide was removed as part of the
00:42:35reconstruction of the building.
00:42:37A Hong Kong photographer and editor who became famous online went even wilder with his imagination
00:42:44and designed a double-decker bus with a slide.
00:42:47It's not his only futuristic photography masterpiece, as he likes to play with perspective and proportions.
00:42:54I can totally see myself sliding away when someone asks me to pay for the ride.
00:43:02In California, there's this light bulb that has been shining bright since 1901.
00:43:08Originally a 30-watt lamp, this special thing now emits a cozy glow, similar to a 4-watt nightlight.
00:43:14It was created by a French inventor, Adolphe Chayet, who produced the hand-blown carbon-filament
00:43:20common light bulb back in the late 1890s.
00:43:23The bulb's journey took an interesting turn when the company's owner donated it to the
00:43:27local fire department.
00:43:29Since then, it has hardly ever been turned off, earning the well-deserved title of the
00:43:34world's longest-lasting light bulb.
00:43:38Now let's shed some light on the lifespan of modern versions.
00:43:42The lifetimes depend on the brand, technology, and type.
00:43:46Nowadays, a new generation bulb can last beyond 20,000 hours.
00:43:51We went forward in technology and developed much further, but a light bulb from two centuries
00:43:56ago was more durable than the recent ones.
00:43:58That's kind of weird.
00:44:00And if you noticed, this contradiction isn't limited to light bulbs.
00:44:04It's like everything we buy these days tends to break down much faster than it used to.
00:44:10Well, that's because of something called planned obsolescence.
00:44:14It's when companies design products to wear out quickly or become useless in a short amount
00:44:19of time.
00:44:19The sneaky idea behind this is to make you buy new stuff or upgrades.
00:44:24Some countries have actually banned this practice because, hmm, it's not cool.
00:44:28It all started with the car industry in the United States back in 1924.
00:44:32This guy named Alfred P. Sloan Jr., who worked for General Motors, suggested releasing new
00:44:38car models every year to keep sales going.
00:44:41Planned obsolescence works best when a company has a bit of a monopoly or at least very few
00:44:46competitors.
00:44:47Before they implement this tactic, they need to be pretty sure that you'll come back to
00:44:51them for a replacement because you're loyal to their brand.
00:44:54They know how long the product is designed to last, but you don't.
00:44:58Interestingly, products tend to last longer when there's more competition in the market.
00:45:03For example, when Japanese cars with longer lifespans hit the American market in the 1960s and 70s,
00:45:11American car makers had to step up their game and make more durable cars to keep up.
00:45:17So, what's good and bad about planned obsolescence?
00:45:21Well, from the manufacturer's point of view, it's great.
00:45:24It helps them make money and keeps the economy rolling because people continue buying new stuff.
00:45:29It also pushes companies to invest in research and development, which can lead to cool innovations.
00:45:35But on the downside, there's a load of waste involved.
00:45:38We're talking tons of it, plus we're using up precious resources.
00:45:43There are different types of this notion.
00:45:46Systemic planned obsolescence happens when your computer or other gadgets can't handle the latest updates
00:45:51or connect with new accessories because the technology has changed.
00:45:56If it's perceived, then the perspective around the item changes.
00:46:00For instance, smartphone or fashion designers change the style of their products to make
00:46:06the older ones seem less cool.
00:46:08And if it's dated, then yeah, there's this secret extermination date.
00:46:13Some products just stop working and get turned off after a certain date, forcing you to buy a new one.
00:46:20Then there's legal planned obsolescence.
00:46:23This is when a law is passed that makes it illegal to use certain products.
00:46:29Some products are designed with the phrase, no repairs allowed in mind.
00:46:34Have you ever tried fixing your broken electronics?
00:46:37Well, some companies make it impossible by developing their products in a way that you can't open them
00:46:43or replace parts.
00:46:44Another production strategy is made to break.
00:46:47Some products are purposely designed to wear out quickly.
00:46:51Manufacturers use flimsy materials that get easily damaged or worn out.
00:46:54And sometimes, you can't even upgrade the software on your computer or phone because it's not compatible anymore.
00:47:01How about those non-replaceable batteries?
00:47:04You know those devices that have built-in batteries you can't change?
00:47:08Well, after a couple of years, those batteries go down.
00:47:11And you're forced to buy a whole new device instead of just replacing the battery.
00:47:16We experience the same thing with clothes as well.
00:47:19Vintage pieces tend to last for decades.
00:47:21But if you buy a new t-shirt, even if it's from a decent brand, you get issues after a
00:47:26couple of years.
00:47:27We didn't arrive at this point in a day.
00:47:29A recent study made about tights revealed a new secret.
00:47:33It turns out that clothing brands are intentionally making women's tights that are prone to laddering,
00:47:38causing them to be thrown away after just six uses.
00:47:41Our grandmother's tights withstood way more wear and tear than ours.
00:47:47130 million pairs of tights are sold in France alone every year.
00:47:52In this study, almost two-thirds of the participants indeed admitted that their tights barely made it past six uses.
00:47:59I mean, they didn't get bored of wearing them.
00:48:02The tights became unwearable due to their fragile nature.
00:48:06On average, women end up buying around 10 to 11 pairs of tights per season to keep up with the
00:48:11constant need for replacements.
00:48:13The study pointed fingers at the two main culprits.
00:48:16Poor quality fabric, and the use of additives that supposedly make the tights less durable.
00:48:23Apparently, tights manufacturers produce them more like tubes to cut costs,
00:48:27neglecting the natural contours of human legs.
00:48:30They also seem to lack the attention to detail that comes with finishing products by hand.
00:48:36The clothing game, in general, has seen some major transformations in recent decades.
00:48:42And it's all been influenced by a bunch of different factors.
00:48:45We're talking about technological advancements, shifts in how we shop, and changes in how clothes are made.
00:48:52Back in the day, clothes were generally made of natural materials like cotton, wool, and silk.
00:48:59They were meant to hang around in your wardrobe for ages.
00:49:03But, now, things have taken a turn.
00:49:06The spotlight is on synthetic materials like polyester and nylon.
00:49:10Sure, they're cheaper to produce.
00:49:12But they might not hold up as well, or feel as comfy.
00:49:17Oh, and let's not forget the rise of fast fashion.
00:49:20It's all about producing tons of super cheap clothes that you wear for a hot minute before tossing them aside.
00:49:26Quality isn't always the priority here.
00:49:29Speed and low cost are the big players in the game.
00:49:33But, hey, don't lose hope.
00:49:36There's a brighter side to this story.
00:49:38More and more people are jumping on the sustainable and ethical fashion train.
00:49:42They want clothes made from eco-friendly stuff and created under fair labor conditions.
00:49:47And guess what?
00:49:47This movement is bringing quality and durability back into the spotlight.
00:49:52Brands are stepping up their game and making clothes that are built to last.
00:49:55So, yeah.
00:49:57The clothing world has seen some big changes.
00:50:00With the rise of fast fashion, we've seen a shift toward cheaper and less durable materials.
00:50:05But at the same time, there's a growing crowd pushing for sustainable, ethical, and high-quality fashion.
00:50:11It's like a fashion tug-of-war, but we'll see who wins in the end.
00:50:17Back to the reliability of cars nowadays.
00:50:19It seems like new vehicles are experiencing more breakdowns.
00:50:23And it's not just the typical engine and gearbox issues that some brands used to have.
00:50:28Nope.
00:50:29Now it's the climate control systems, electrics, in-car entertainment units, onboard electronics,
00:50:34and even power windows that are giving up in the first few years.
00:50:39This tech issue isn't, of course, specific to automobiles.
00:50:43Apple admitted to deliberately slowing down iPhones.
00:50:46Then there are refrigerators.
00:50:48They've got a compressor problem.
00:50:50Those last only about one-third to one-fourth of their previous lifespan.
00:50:54They also have red flags related to their doors.
00:50:57Instead of being screwed on tightly, they're sort of glued in place.
00:51:00All that pulling the door in the middle of the night when you can't sleep can lead to trouble.
00:51:05Over time, the doors lose their friction and start acting all wobbly.
00:51:11Overall, there's a bright side to this notion.
00:51:14Now there are products that are made to last less to help the environment.
00:51:17For example, seaweed bags instead of plastic bags.
00:51:20Fancy a cup of tea?
00:51:22Then dissolvable tea bags got you covered.
00:51:24Edible water blobs and edible spoons are next-level inventions.
00:51:28Numerous brands sell detergent or shampoo pods and toothpaste tablets.
00:51:37Wow, look at that!
00:51:39One Reddit user has grown a perfectly square salt crystal.
00:51:43And the best thing?
00:51:45It's edible!
00:51:46People in the comments shared their experience of growing salt crystals.
00:51:50They say that the best way to get such beautifully shaped crystals is by leaving a dish with salty water
00:51:57indoors for a month.
00:51:58The water will gradually evaporate and you'll have your crystals.
00:52:03This sure looks like a futuristic picture, but it's actually a real-life place.
00:52:09That's what was left after a volcanic eruption at the Cumbre Vieja Ridge in La Palma, Canary Islands.
00:52:15Now, I wonder what they're going to do with all that ash.
00:52:19It doesn't seem like it's impossible to just plow it away or wait for it to melt.
00:52:24Uh-oh, look at this tree.
00:52:27It seems to be desperate to get some help.
00:52:29Who knows what troubles it?
00:52:31Well, in reality, the tree has grown around this sign.
00:52:34And now, only the word help is visible.
00:52:39Look at this teeny lightning bolt.
00:52:41How cute is it?
00:52:43Haha, just kidding.
00:52:44Someone just managed to capture a picture of them shocking their girlfriend.
00:52:49Still awesome.
00:52:51This circle appeared in the evening sky over Beijing, China.
00:52:55One Reddit user posted it and triggered a discussion about the nature of this bizarre phenomenon.
00:53:01Most people agreed with the theory that it was the reflection of a light show.
00:53:06Now, for some reason, this person stabbed a bottle of hand sanitizer with a tack.
00:53:12A few months later, they spotted something was growing on that tack.
00:53:17Ugh, can it just be good old rust?
00:53:20Whatever it is, that's one thing I'm not sure about.
00:53:23No one should use this sanitizer anymore.
00:53:27This is one of the most unbelievable and, at the same time, revolting findings.
00:53:33It's a snake shedding, and it comes together with the eye skin.
00:53:38Ew!
00:53:39All because snakes don't have eyelids.
00:53:42Instead, they have eye caps, specially adapted scales covering their eyes.
00:53:48And during a shedding cycle, these eye caps also come off.
00:53:54Ah, look at this beauty.
00:53:57Someone has grown this crystal from scrap copper and vinegar.
00:54:00It's scientific name is copper acetate.
00:54:04It took the person seven months to grow such a large crystal.
00:54:08And it formed this way naturally.
00:54:11No one polished or cut it.
00:54:13Oh, and do you see that tiny tail?
00:54:16It's there because the crystal was grown on a piece of fishing line.
00:54:21Are these also some crystals?
00:54:24Frost?
00:54:25Spiderweb?
00:54:26Nope.
00:54:27It's just a red crayon on paper under a microscope with 400 times magnification.
00:54:34And this Reddit user from Sweden was going to work when they came across a geothermal anomaly.
00:54:41Look at this rock sticking out of the snow.
00:54:44It was warm to the touch.
00:54:46A bit warmer than human body temperature.
00:54:48There were also no tracks around this spot.
00:54:52So, what's your bet?
00:54:54What is this thing?
00:54:55Share your ideas in the comments below.
00:54:58And this person accidentally found a mushroom.
00:55:02Yes, a large legit mushroom growing inside a glass globe.
00:55:07I wonder how it got there.
00:55:08And most importantly, why?
00:55:12Someone found an old light bulb in their grandparents' house.
00:55:16Its construction was finished in 1902.
00:55:19And still, the light bulb still functioned.
00:55:22I wish everything in my life was as reliable as that light bulb.
00:55:27Wow, marriage certificates were literally next level in the past.
00:55:32Look at this marriage certificate from 1895.
00:55:36It was discovered during the renovation of a cabin.
00:55:39Isn't it absolutely amazing?
00:55:43This tree is pretty cool.
00:55:45Its roots have long outgrown their spot.
00:55:47But look.
00:55:48It's still trying to keep them in check.
00:55:50Or rather, in shape.
00:55:53Rectangular shape.
00:55:55Uh-oh.
00:55:56Someone's lost their cell phone.
00:55:58They must be devastated.
00:56:00But you know what?
00:56:01It's Nokia.
00:56:02I bet it still works.
00:56:04Have you ever seen a cut tree?
00:56:06If so, you must have noticed a series of concentric rings.
00:56:11These rings can tell you a lot about the tree.
00:56:14How old it is.
00:56:15What the weather was like during each year of the tree's life.
00:56:18Dark rings represent wood that grew in the late summer or fall.
00:56:23And light-colored rings represent wood that grew in the spring and early summer.
00:56:27So one light and one dark ring mean one year of a tree's life.
00:56:32But look at this tree.
00:56:34What can we say about it?
00:56:36Um, I'm not really sure.
00:56:38Maybe that it's pretty, unique, and apparently likes to stand out.
00:56:45This isn't your regular tomato.
00:56:47Oh no, this one is a bit creepy.
00:56:50Because it seems to be growing more tomatoes inside its own body.
00:56:55Unsettling.
00:56:56And this person bought an ice cream cone.
00:56:59The only thing missing was the cone.
00:57:02Duh, I'll never call myself unlucky anymore.
00:57:06Some insect, perhaps a caterpillar, chewed on this leaf.
00:57:10But by doing so, it created a beautiful, symmetrical design.
00:57:15Do you think it was an accident or a plan?
00:57:19Another person bought this watermelon.
00:57:21Little did they know that after cutting it, they would be in for a nice surprise.
00:57:26Because just how beautiful is that?
00:57:28What would you do if you found such a watermelon?
00:57:32Be very attentive while roaming the streets of Rome.
00:57:36Because you can come across such an amazing piece of art.
00:57:39A face carved into a cut tree.
00:57:43And this, may I call it a monster?
00:57:46Because it sure looks like one.
00:57:48Anyway, a couple found this thing while they were hiking in a forest.
00:57:52I bet they were scared.
00:57:54At least at first.
00:57:56On the other hand, I have a suspicion that someone helped this tree look this terrifying.
00:58:00What do you think?
00:58:03Hmm.
00:58:04This one looks like a hieroglyph to me.
00:58:07But no.
00:58:08If we look closer, it becomes apparent that road workers were just playing a game of tic-tac-toe.
00:58:14The nerve of them.
00:58:15Would you get scared if you found this message on a random banana in a supermarket?
00:58:21Duh.
00:58:22I've got so many questions.
00:58:23Who exactly is coming?
00:58:25Why are they coming?
00:58:26And many more.
00:58:28One Reddit user found four or five such concrete shoes scattered around their town.
00:58:34They got curious.
00:58:35But no one could tell them who had made these shoes or why they had done it.
00:58:41And this person was lucky.
00:58:43Or should I say, unlucky?
00:58:45To find a cucumber without any seeds in it.
00:58:48Unlike this next Reddit user, when they opened their ice cream, they found five sticks in it.
00:58:53How did they even fit?
00:58:55There's more wood than ice cream here.
00:58:59I've heard that medical students sometimes perform surgeries on grapes to acquire basic microsurgical skills.
00:59:06Do you think something like that could have happened to this tomato?
00:59:10Someone found it in their garden.
00:59:12And doesn't it look as if someone had already cut it apart and then stitched it back together?
00:59:18Now look at this piece of cheese.
00:59:20What does it remind you of?
00:59:22Come on.
00:59:23Doesn't it look like an edible piece of marble?
00:59:27This truck has been parked in this spot for more than 10 years.
00:59:31Apparently, it was long enough for a tree to grow from behind its bumper.
00:59:36Um, the next picture is really hard to explain.
00:59:39Has the flame just moved away from the wick?
00:59:42Have they had an argument?
00:59:43Have they broken up?
00:59:45This leaves me with so many questions.
00:59:48One family got a real wake-up call when they received this newspaper.
00:59:51The sofa in the advertisement was exactly the same as their own.
00:59:55It must be a sign.
00:59:57They should really consider replacing this piece of furniture.
01:00:01If you tend to have problems choosing between red and white grapes,
01:00:04why not find a branch that has both, just like this person did?
01:00:09In this part, someone has messed up with copy paste.
01:00:13I can't find any other explanation for the bizarre positioning of these benches.
01:00:18Can you?
01:00:20Someone has taken the request,
01:00:22just throw down a towel and save a spot for us a little bit too seriously.
01:00:27Have you ever seen such tiny bananas?
01:00:30Neither have I.
01:00:31And this little patch of cloves has chosen to grow in a bottle.
01:00:35Because why not?
01:00:41I have a collection of questions you've always wanted the answers to.
01:00:45Let's go!
01:00:47First, an observation.
01:00:50Cookies and baguettes are basically kinds of bread.
01:00:53So, my question is,
01:00:55why when left outside for the night,
01:00:57a cookie gets soft and a baguette becomes hard?
01:01:01It doesn't make any sense.
01:01:04Well, the thing is, cookies are sugary bread.
01:01:07The sugar and salt in them soak up the moisture from the atmosphere.
01:01:11So, they get soft.
01:01:14Baguettes don't have much salt and sugar,
01:01:16so they don't attract water and just dry out.
01:01:21Superglue sticks everything to everything.
01:01:24But how come it doesn't get stuck to the tube?
01:01:27Turns out that the glue needs some compound with hydrogen to polymerize.
01:01:33In the tube, there's just oxygen and no water.
01:01:36But outside, there's plenty of moisture.
01:01:40Also, this explains why the stuff always sticks so well to your fingers.
01:01:44They're warm and perfectly moist.
01:01:49I'm sure you cried at least once when cutting an onion.
01:01:52Why does it happen?
01:01:54So, onions and garlic contain amino acids.
01:01:57And one of the compounds gets decomposed when being sliced.
01:02:01It turns into an irritator when it comes in contact with water.
01:02:05In particular, your eyes.
01:02:08Your eyes release tears to wash the irritant away.
01:02:11So, that's why you cry.
01:02:13There are a couple of tricks that can prevent it.
01:02:16When cutting an onion, try keeping a sugar cube between your teeth.
01:02:19It'll absorb the irritant.
01:02:21Another life hack is to hold a small piece of bread between your lips.
01:02:25It can help you too.
01:02:28Why do you see things when rubbing your eyes?
01:02:31These colors and shapes are called phosphenes.
01:02:34The reason why you see them is that when rubbing, you increase the pressure in your eyeballs and activate the
01:02:40neurons of the retina that process visual information.
01:02:43Once they're activated, your brain interprets it as seeing something.
01:02:49When you don't get enough sleep or are just too tired, you get those dark circles around your eyes.
01:02:56Want to know why?
01:02:57The skin under the eyes is very thin.
01:03:00So, blood vessels are very close to the surface there and you can see any difference easily.
01:03:05If you have a lack of sleep, your skin gets paler and the blood vessels are even more visible.
01:03:11So, you can see those dark circles showing through the skin.
01:03:15Also, with age, the skin naturally gets thinner.
01:03:18So, that's why older people tend to have dark circles.
01:03:22But, if you're young, just try to get more sleep.
01:03:26Let's pay a bit of attention to backpacks.
01:03:29They have a few interesting features.
01:03:32First, some of them have sternum straps and they are quite helpful.
01:03:36They allow you to redistribute the weight of the backpack a bit,
01:03:39lifting some of it from your shoulders.
01:03:42Not much, but just enough to make your backpack lighter and easier to carry.
01:03:47And, of course, the sternum straps prevent the shoulder straps from sliding off.
01:03:53Okay, the next thing is gear loops.
01:03:56And probably from the name of it, you already have an idea of what you need them for.
01:04:01You can strap in some useful gear you need with you, like trekking poles or shovels.
01:04:06Some gear will need to be secured to do it.
01:04:09Drop the handle through the loop and rotate it upward.
01:04:12Then, secure it with the elastic hook at the top.
01:04:15And you're golden.
01:04:18And yes, all backpacks have loops.
01:04:21Actually, I never thought of their purpose until today.
01:04:23Some people say that if you slide your thumbs through them,
01:04:27it makes the backpack sit tighter on your back, making it more comfortable.
01:04:32Other people just rest their hands there.
01:04:34But the reason why they're there is probably to prevent the ends from sliding back from the buckles.
01:04:39That would be quite a headache to slide them back all the time, right?
01:04:46Okay, let's look into some other ordinary stuff we've never paid attention to.
01:04:50Let's take, for example, jeans.
01:04:53They have those metal rivets.
01:04:55It turns out that they've been there as long as jeans exist.
01:04:59Jacob Davis, the man who made the first pair of jeans,
01:05:03added copper rivets to places where the pants were more likely to rip to make them stronger.
01:05:09So, it was a crucial detail to keep jeans together.
01:05:13Today, they have a more decorative purpose because they're distinctive and traditional for jeans.
01:05:20Also, many zippers have the letters YKK engraved on them.
01:05:25Those are the initial letters of Yoshida Kogyo Kabushiki Gaisha.
01:05:30It's the name of a Japanese company that can be translated as Yoshida Manufacturing Shareholding Company.
01:05:36It's the largest zipper manufacturer in the world,
01:05:40so all zippers produced by them are marked with these letters.
01:05:43It's estimated that the company produces half of all zippers in the world.
01:05:50That's why you see their zippers more often than any others.
01:05:56Have you noticed that canned and bottled soda seems to taste different?
01:06:00You're not wrong.
01:06:01That's actually true, and there's even science behind it.
01:06:06Chemists say that aluminum cans have a polymer layer that absorbs some of the soda's taste,
01:06:11so cans indeed change the taste.
01:06:14Chemicals in a plastic bottle can add some acetaldehyde,
01:06:18a byproduct that gets formed while plastic is melted, to the drink.
01:06:22So, they also change the taste a bit.
01:06:25You never really drink the original drink.
01:06:28If you want to try the real thing, buy sodas in glass bottles.
01:06:32When soda is stored this way, its taste is the most similar to the original one.
01:06:39Plastic bottles with soft drinks have five bumps on the bottom,
01:06:43and water and juice plastic bottles have almost flat bottoms, except for a little kink.
01:06:48It's not random.
01:06:49A plastic bottle is made by putting a plastic tube into a mold and blowing some air inside to make
01:06:56it expand until it takes the needed shape.
01:06:59The problem is that at the bottom, the bottle will always have an outward kink that will make the bottle
01:07:06unstable.
01:07:07To avoid it, some air is also pushed inward from the bottom, creating that small punt at the base of
01:07:15it.
01:07:15Flat bottle bottoms are common because they need less plastic to be made, but soft drinks and sparkling water need
01:07:22special treatment.
01:07:24These liquids have internal pressure that can push the plastic outward, messing up with the punt and the stable form
01:07:31of a bottle.
01:07:33So, soda bottles have a curved shape because this way, they're more pressure-resistant.
01:07:40Compare folding a regular piece of paper to folding a paper tube.
01:07:44The latter will have more resistance.
01:07:46In the same way, curved plastic is more resistant to any pressure.
01:07:53Take a closer look at your bag of chips.
01:07:56You can probably find these little colored circles.
01:07:59They're made by the manufacturer to test the print that is used on the package.
01:08:04They're called color control patches.
01:08:07The circles are not the same palette as the final package.
01:08:10They're layered on top of each other to achieve the final color of the bag.
01:08:16So, why do manufacturers need them again?
01:08:19Imagine that something is off and the printing machine prints a bunch of wrong packages.
01:08:24That's a lot of wasted money.
01:08:26So, these control patches are there to make sure that the final print is going to be correct.
01:08:32If they're off, the manufacturer will know that the whole package is going to be off too.
01:08:38These patches allow the printers to find a surplus or a deficiency of color and solve the issue.
01:08:45But don't worry if you don't find these circles.
01:08:48They probably just got cut off.
01:08:51Take a good look at a milk jug.
01:08:54There's often an inverted circle on one of the sides.
01:08:57This dimple is there to make the jug more resistant and to prevent it from rupturing if the jug falls
01:09:04on the floor.
01:09:05The dimple gives some more space for the liquid to expand.
01:09:09Also, as the expiration date approaches, the microbes in the milk start to expel some gases.
01:09:16As more and more of them get trapped inside, the pressure in the jug rises.
01:09:21The dimple accommodates the expansion and prevents the jug from bursting.
