00:00Want to play a game? Can you count how many technical gadgets you use during your day?
00:06Don't forget to count your router, lint remover, and every light bulb.
00:10Well, 5? 7? Maybe 15?
00:15Studies claim that the average household in the USA currently owns around 25 electronic devices.
00:22In 2019, this number was more than half lower.
00:26The modern speed of life makes it so easy to forget that our everyday essentials have history.
00:32Let's do some time travel to refresh our memory.
00:35Chances are you'll never take your toilet paper for granted again.
00:40You wake up to the annoying sound of an alarm clock.
00:43This is how it looked like 1,000 years ago.
00:47Just kidding, it's a rooster.
00:48These birds did a great job helping people wake up at dawn before an American named Levi Hutchins
00:54invented the first alarm clock in 1787, but this device could only ring at 4 a.m.
01:00It took mankind 60 more years to create a technology allowing us to set the alarm time manually,
01:06and around 170 more years to invent an alarm that wakes you up with your favorite aromas.
01:15And now it's time to brush your teeth.
01:17Which toothbrush would you rather choose?
01:20The first one is actually a vintage shoe brush.
01:24You should probably choose this sophisticated gold-plated tool.
01:28In fact, it's a toothbrush made for Emperor Napoleon Bonaparte between 1790 and 1821.
01:36But, of course, people realized that their teeth needed care much earlier.
01:41Ancient Egyptians used branches with frayed ends to rub against their teeth.
01:45And the first bristle toothbrushes date back to 1498.
01:51Chinese craftsmen manufactured bristles from hog hairs.
01:55360 years later, in 1857, American inventor H.N. Wadsworth patented the prototype of the modern toothbrush.
02:04And the first electric toothbrushes popped up in stores in 1960.
02:09You've just washed your hair.
02:11Time to do some styling.
02:13Would you risk putting your head inside this vintage hairdryer?
02:16A stationary hairdryer was invented in 1890 in France.
02:21Although it looks pretty claustrophobic, it was very popular in beauty salons before the era of portable hairdryers came over.
02:30Let's move on to the toilet.
02:32How about using a stone instead of toilet paper?
02:34In ancient times, people chose various materials to clean up, including leaves, grass, animal furs, water, seashells, and even stones.
02:45Rumor has it that ancient Greeks preferred using ceramics with their enemies' names.
02:49And in 1857, an American named Joseph Gaiety first marketed the modern toilet paper.
02:56He called it simply,
02:58Medicated Paper for the Water Closet.
03:00The paper was sold in packages of 500 sheets for 50 cents, which is worth $17 in today's money.
03:08And this is what your flush toilet would look like if you lived in 1592.
03:14Sir John Harrington, godson of Elizabeth I, created this masterpiece in England.
03:20It's basically a water closet with a raised cistern and a small downpipe through which water runs and flushes the
03:26waste.
03:29Time to cook some breakfast.
03:31These old kitchen stoves are no more than wood-burning cook stoves.
03:35But as the age of invention took place, stoves evolved to fit modern homes.
03:40Gas stoves first appeared in 1826, and in 100 years, they were used in most domestic kitchens.
03:49And now, let's boil some water to make tea.
03:52Before the 19th century, most kettles were made of iron.
03:57People placed them directly on the flame.
03:59That's why such kettles needed constant cleaning.
04:02Mesopotamian tea lovers made their kettles from bronze,
04:05and it took an effort to make all these sophisticated decorations.
04:10But the first electric kettle appeared only in 1891 in the USA.
04:15It took about 12 minutes to boil water,
04:18because the water and the heating elements were placed in separate chambers.
04:22Luckily, the modern kettles do it in a blink of an eye.
04:27Well, now, can you guess what this device is for?
04:30Nope, it's not a sewing machine.
04:32It's an electric toaster.
04:34This is what it looked like in 1893, when it was first invented in Scotland.
04:40Nowadays, toasters look more aesthetically pleasing and take less space.
04:46Speaking of space, the first hard disk was the size of a cupboard,
04:50and its storage was only 5 megabytes.
04:53But today, we have 32 gigabyte disks that are used in cameras and mobile phones.
04:59Just imagine how much information you could fit in a cupboard
05:02if you could fill it fully with such disks.
05:05The correct answer is...
05:07A lot!
05:09Your friend is calling. Pick up the phone!
05:12But get straight to the point.
05:14It only has about 20 minutes of battery life.
05:16This massive tool is the world's first mobile phone made by Motorola in 1973.
05:23It weighs 2.5 pounds and costs $4,000, which is around $27,000 in today's money.
05:33Time to get dressed for work!
05:35Would you risk ironing your crispy white shirt with such a device?
05:38Well, people used to take that risk before inventing the first electric iron in 1882.
05:43And this cute creature is an antique gas-powered iron made at the beginning of the 20th century.
05:50Earlier, they just put coal in the iron to heat it up.
05:55Is it too sunny outdoors?
05:57No problem.
05:58Put on this stylish accessory.
06:00Snow goggles were invented centuries ago to protect eyes from snow blindness.
06:06And this simple item has eventually evolved into sunglasses that we use today to hide from UV light.
06:14Why is everything so blurry?
06:17Did you forget to put on your contact lenses?
06:20Today, over 150 million people worldwide use them on a daily basis.
06:26But the first guy to get this brilliant idea lived in the 16th century.
06:31And his name was...
06:32Leonardo da Vinci.
06:34In 1508, he described a method of directly affecting the cornea by putting the head in a bowl of water.
06:41Or just wearing a water-filled glass hemisphere over the eyes.
06:45But it took people around 400 years to bring that idea to light.
06:51And meanwhile, humankind used eyeglasses.
06:54The ancient ones used to have lenses made out of quartz and metal frames.
06:59Of course, their design was too heavy to be considered fashionable.
07:02But, thankfully, today we enjoy a wide variety of frames in different styles.
07:08And designs with glass or plastic lenses.
07:13It's time to hit the road.
07:15Would you mind riding this bike?
07:17That's right.
07:18It doesn't have any pedals.
07:19First bicycles didn't have a saddle, a braking mechanism, or pedals.
07:23That's why people simply called it the running machine.
07:27Also, manufacturers offered models with a bigger front wheel for higher speeds.
07:32Thankfully, speed and comfort characteristics evolved over time and continue to do so today.
07:40Take a look at this amazing rainbow.
07:43We got to take a picture immediately.
07:46Unfortunately, 40 years ago, this photo would have looked something like this.
07:50No color, no clarity.
07:52It was the time when digital cameras had just appeared.
07:55They weighed 9 pounds and they could only take black and white images.
08:00But the progress is impressive.
08:03Today, it takes just one click to make a high-resolution picture or video on your phone.
08:10Finally, you arrive at the office and see this mysterious device.
08:15Can you recognize its purpose?
08:17It's an old-school printer.
08:19The first printing devices appeared in the 15th century in Europe.
08:23And they were way bigger and heavier than the modern ones that we use in offices and homes.
08:30Your shirt got dirty after a long day at work.
08:33Which machine would you rather choose to wash it?
08:36The right device is a wiser choice because it's electric.
08:40The left washing machine can wash up to 10 shirts, but it's only operated with a hand crank.
08:47Someone has spilled popcorn on the floor.
08:50Let's clean this up.
08:51But can you guess which of these two devices is the real vacuum cleaner?
08:55The left one.
08:56The right device is a vintage lawnmower.
09:00The first vacuum cleaners appeared in 1901 and they were petrol-driven.
09:05It took a while for this device to evolve into a vacuum cleaner robot free of any tubes and wires.
09:12Just take a look at these two pictures.
09:14These devices don't even look like they're from the same planet.
09:21Supermarket shopping carts usually look simple, but they hide tons of secrets.
09:25They often shake when moving and sometimes even make loud clinking noises.
09:30But that's not because they're old or of bad quality.
09:33This is a psychological trick.
09:36The faster you walk, the louder the noise the cart makes.
09:39Trying to produce as little noise as you can, you start walking more slowly.
09:43And, of course, you can't but pay attention to all that yummy stuff on the shelves.
09:48And if some of it ends up in your cart, well, you can't blame yourself, right?
09:53Another trick supermarkets use to make you buy more is the size of carts.
09:58They're usually extra large and you'll subconsciously take more products to fill all that space.
10:06Now, have you ever noticed that shopping cart wheels often wobble?
10:10Even worse, there's almost always that one wobbly wheel that makes it impossible to steer the cart.
10:15And you have to go back to switch it.
10:18Shopping carts have caster wheels.
10:19Those are mounted on the bottom of large objects so that you can move them around more easily.
10:24But over time, casters develop flutter.
10:27It causes the wheel to swivel back and forth.
10:31This is kind of inconvenient since such flutter can make your cart move in an unwanted direction.
10:37Interestingly, flutters are less likely to occur when you're moving slowly.
10:40So, can it be that supermarkets don't repair fluttering wheels because they want customers to move around at a more
10:49leisurely pace?
10:50Just a thought.
10:52The black lines on the basketball make it easier to use.
10:56They're actually grooves helping you to handle the ball.
10:58And since players need to move around the court while bouncing the ball, control is crucial.
11:04Those pebbled dots that cover the outside of the ball serve the same purpose.
11:10Do you have an eye for detail?
11:12Then you might have noticed a strange-looking notch at the bottom of some plastic bottles.
11:18It's called a deco lug, and it helps to indicate the placement of a bottle sticker or some artwork.
11:24Without it, stickers on mass-produced plastic bottles won't look as pretty and symmetrical as they usually do.
11:32Most plastic coffee cup lids have a tiny hole in them.
11:35When you take a sip from a cup closed with a lid, the air pressure inside the cup drops.
11:40And some air from the outside tries to push into the cup.
11:44The tiny hole in the lid allows the air to enter.
11:47It also helps the liquid go out of the main, bigger hole more smoothly.
11:52Plus, the smaller hole acts as an exit for steam gathering inside the cup, which prevents the lid from melting.
12:01Those of you who have a ceiling fan, do you know it can move in more than one direction?
12:06One mode is for the summer, the other for the winter.
12:10When the weather is hot, ceiling fans should move counterclockwise.
12:14This makes them pull the warm air up and push the cold air down.
12:18And the clockwise winter mode pushes the warm air down and helps the cool air rise.
12:25Do you still use a knife to remove strawberry stems?
12:28But this way, you throw away a lot of the stuff you could otherwise eat.
12:33Instead of a knife, try a regular drinking straw.
12:36Insert one end of the straw into the bottom of the strawberry and push it gently all the way through.
12:41The straw will pop the stem out.
12:46A little groove on the bottom of a cup lets cool air get underneath it,
12:50which saves the glass or ceramics from cracking when a scorching beverage heats it up.
12:54And when you place cups upside down in the dishwasher, the groove stops water from gathering in the cup's bottoms.
13:03A button on the back of a collar of a button-down shirt is there to prevent your tie from
13:08sticking out.
13:09And the small loop on the back can be used to hang the shirt without wrinkling it.
13:15Barcode readers scan not black, but white lines.
13:18The reader emits rays of light that fall on the product's barcode.
13:22When it happens, the white areas reflect this light, while the dark zones absorb it.
13:28The reflected light helps the device to read the code and give you some information about the product.
13:35White is the most popular color for painting aircraft.
13:39It reflects sunlight most effectively, and planes don't heat up too much.
13:43All kinds of cracks or dents are much more visible on the white background.
13:48It means issues can be spotted and repaired as fast as possible.
13:52And finally, it costs less to buy white-colored airplanes, because it's the color they have at birth.
14:01Some keyboards come with little legs.
14:03Thanks to them, you can tilt your keyboard and see which keys you're hitting.
14:07But keep in mind that a flat keyboard doesn't make your wrist so tired.
14:11And if you can touch type, you don't need to look at the keyboard anyway.
14:17Let's say you're driving on a highway.
14:19When it's time to make an exit, pay attention to highway signs.
14:23If the sign for your destination is on the left, your exit will be on the left too, and vice
14:28versa.
14:30You might have noticed that the sides of some cotton pads have different textures.
14:34One surface is firmer and more absorbent.
14:37It's supposed to be used with nail polish remover.
14:39The other side is way finer and softer.
14:43You can use it to remove makeup.
14:46You often see that cups on small tubes are hollow on top, with a little spike inside.
14:52The purpose of this spike is to break the foil sticker, sealing the tube.
14:57The neck of the tube fits right in the hole, and the spike breaks the seal.
15:01No need to struggle trying to tear the tiny foil seal off with your fingers or even your teeth.
15:08The hole near the rim of your bathroom sink is there to prevent overflows.
15:13Thanks to it, all excess water goes into the siphon.
15:16Plus, it helps your sink drain faster.
15:18The hole gives air gathered in the siphon room to escape.
15:24Let's say you're reading a paper book, but when you decide to take a break, you realize you don't have
15:29a bookmark.
15:30Is leaving a dog ear your only choice?
15:33Nope, that's what the dust jacket is for.
15:35Turns out, providing you with the information about the book and its author isn't its only purpose.
15:42Most kitchen shears have metal plier-like teeth in the middle, between the handle grips.
15:47They can help you crack nuts, crab shells, and other tough products.
15:52You can also open jars and bottles or remove herb stems with their help.
15:58The bubbles in your soda push the straw up, but you can keep it from rising by pushing it through
16:03the hole in the metal pull ring.
16:06The correct way to break off a piece of Toblerone chocolate bar is by pushing the pointy side inwards, towards
16:12the rest of the bar.
16:15Bottles have long necks so that your drink stays cool longer.
16:18Hold the neck, not the bottle itself, and your drink won't warm up.
16:23Place a wooden spoon across the top of a pot with pasta.
16:26It'll prevent the bubbles from escaping.
16:29Once they touch the spoon's water-repelling surface, they'll immediately retreat back into the pot.
16:36If you turn over a Tupperware container, you'll see lots of symbols.
16:41They'll inform you whether the container is dishwasher, microwave, or freezer safe.
16:46You're also likely to find out how you should recycle the thing.
16:50The black grate on microwaves is called a Faraday shield.
16:54It keeps the electromagnetic energy inside the device.
16:57The grate also speeds up the heating process, and it can block phone signals too.
17:04If you don't remember which side of your car the gas tank is on, check the fuel gauge on the
17:09dashboard.
17:10There must be a little gas pump with an arrow pointing to the left or right.
17:14It indicates the side you should choose before pulling up towards the pump.
17:20A well-trained thief can break into your car in just a matter of seconds.
17:25Well, listen up, because I'm exposing some car burglar secrets.
17:30Technology in cars is getting more advanced.
17:33You might think that carjackers are also using super-advanced tech or gadgets to keep up with the flow.
17:39Well, mostly no.
17:41Old tricks still cover the majority of thefts.
17:44Experts say many drivers fail to take the simplest precautions.
17:4843% of people don't check the door handle to make sure their car is locked before walking away.
17:55So, tip number one, lock your car, and then check again if it's locked or not.
18:00Here is a new generation trick.
18:02Apparently, sometimes all you need to steal a car is a plastic bottle.
18:07Here's the thing.
18:08Thieves walk in a parking lot.
18:10They lay their eyes on a car.
18:12They put an empty plastic bottle over the tire on the passenger side.
18:16The driver starts the engine and the car begins moving.
18:20Ah, what's that crinkling sound?
18:22They get out of the car to check it out and bend down to see what's going on there.
18:27And then the thief comes and either steals the car or grabs the driver's valuables.
18:32The driver's biggest mistake in this case is to leave the car running.
18:37Rule number three is kind of related to these incidents.
18:40Don't leave your car running, like ever.
18:43Police warn that leaving your car keys in your car at a gas station, even while you're pumping gas, is
18:49an open check for thieves.
18:51They can simply hop in your car and go.
18:53I mean, it might seem like a great idea to warm your car up while waiting at home instead of
19:00staying outside in the cold.
19:01But this makes your car a target.
19:04Don't leave the car running when you dash into a store either.
19:07Plus, in at least 30 states, it's not legal to leave a car running and unattended in a store parking
19:14lot.
19:15Now, this may seem obvious, but don't ever leave something valuable in the car, even some change in the cup
19:21holder.
19:21You'd be amazed at how little it takes to attract a car thief.
19:26It's like, is that a…
19:28Yep, I'ma go for it.
19:31Now, more advanced solutions are also available.
19:34Some gadgets lock your steering wheel so that the car can't be driven.
19:38I mean, these devices probably won't stop thieves.
19:41But they will slow them down or at least make them second-guess themselves.
19:46Okay, now, here's something called vehicle identification number.
19:50This number is unique to every car and its owner.
19:53Plus, it's public info.
19:56You can engrave your VIN on every window.
19:58This way, your car will become less valuable on the black market for its parts.
20:03No thief wants to drive a car that can be easily identified as stolen.
20:08Plus, changing the car windows costs a lot, so they won't want to deal with it.
20:13Now, this one is my fave, using a kill switch.
20:17Thieves dislike those very much.
20:19This switch cuts the flow of electricity to the ignition switch or battery and disables the fuel pump.
20:26A hidden switch can prevent thieves from actually stealing your car, even if they've already broken into it.
20:32The joke's on you, thief!
20:34Now, close that door.
20:35Many new models come with a kill switch installed, and older versions can easily get one.
20:40Now, meet Steve Fuller.
20:42He's a former car thief.
20:44He got convicted six times for stealing cars.
20:47But hundreds, yes, you heard me right, hundreds of other times, he got away with it.
20:52He left the dark side, though.
20:54Now, he tries to make up for the things he did.
20:57So, he agreed to tell the world the secrets only car thieves know.
21:01He confirmed that car thieves do not like kill switches.
21:05If they're well hidden, such witches may take some time to deactivate.
21:10Carjackers can't risk wasting too much time on one car, so they will move on to the next vehicle.
21:16Did you know that you might have an extra key in your car?
21:20Some cars have valet keys stashed inside the owner's manual or in the tool kit in the trunk.
21:26If that's true about your car, take the key out.
21:30If you know where it is, thieves will know too.
21:33You think you have a perfect hiding spot for your spare key, huh?
21:37Well, car thieves know where to look.
21:39Some people hide their extra keys under the bumper or beneath the floor mat.
21:44Thieves routinely check those places as well.
21:47Fuller says, glove compartments, center consoles, doors, change trays, you name it, it's there.
21:53I found keys in all those places.
21:56More surprisingly, he admitted that after scoping out vehicles, he'd found the key in 90% of the cars he
22:04had stolen.
22:05Some more interesting information comes from the National Insurance Crime Bureau.
22:09They found out that between 2016 and 2018, nearly 230,000 vehicles had been taken because the vehicle's fob had
22:18been left inside.
22:19Now, speaking of keys, car burglars can open cars by intercepting the signal from their keyless entry system.
22:26Yet, only just 5% of vehicles hide their fobs in an RFID wallet that can protect them from getting
22:33the signal intercepted.
22:35Now, imagine you come home and park your car in front of your house.
22:39You put the car keys on the car hanger near the entrance door.
22:42Bam! In the morning, you may not find your car where you parked it the night before.
22:48Many people believe that putting their keys anywhere at home is safe.
22:53Unfortunately, this is not enough.
22:55Car burglars can use devices to get the signals from keys and unlock devices remotely.
23:01The solution is to keep your car keys far away from the entrance door, in a place where thieves can't
23:07pick up a signal.
23:09Use technology to protect your car.
23:12Alarms with motion sensors are a no-no for thieves.
23:15A GPS tracking device can also be of use.
23:19In the worst-case scenario, it'll help police find your vehicle.
23:23Car alarms are also a real turn-off for thieves, so invest in a good car alarm.
23:28The last line of defense regarding devices is a dash cam with a surveillance mode.
23:34All dash cams are designed to record your drive, but some models also allow you to monitor your car when
23:40you're not around.
23:42You might think that leaving the windows cracked open to let the car fill with fresh air can't do any
23:47harm.
23:48Nope, that little bit is enough for a thief to slide his fast fingers or tools inside.
23:54First the window, then the door.
23:57Fuller says a car with a slightly open window equals finding an unlocked vehicle.
24:03There are nice things about living alone, but finding an unsettling message outside your home isn't one of them.
24:10On a snowy winter evening, a woman left her house to take out some trash.
24:15She noticed that someone had written 1F on the snow-covered trash can lid.
24:20Apparently, this is a short version of 1F.
24:24Someone had been watching her long enough to know she lived alone.
24:28Her car could have been an easy target.
24:30So, experts suggest you take a quick look around every time you leave home.
24:36Another trick carjackers use involves cheese.
24:40Imagine walking to your car and spotting melted cheese on your engine hood.
24:44Is it some kind of a prank?
24:46You begin to clean it away, but it takes ages.
24:50Meanwhile, someone might be watching you from a distance, waiting for the right time.
24:55They're likely to jump into your car and drive away while you're busy dealing with the cheese.
25:01Fuller says car thieves don't really like going to open and visible places, like in front of houses or in
25:07driveways.
25:09Dark and empty locations, such as apartment buildings, carports, and underground parking garages, appeal to them much more.
25:16He says he liked those places because they were very quiet.
25:20He could always hear it when someone was approaching.
25:24So, tip number 14.
25:25Park your car in crowded areas.
25:29In the airport, they usually ask you to take your laptop out of your backpack and put it in a
25:34separate bin while going through the security check.
25:37Laptops are dense and the x-rays can't see through them, so you could be hiding something dangerous there.
25:42If it's out and it's on its own in a separate bin, it's easier for the scanners to capture a
25:47prospective hazard.
25:50Normally, the messages you send using iMessage are blue, but look, this time it turned green.
25:55No need to panic. It's not like the user blocked you or anything.
25:59It's just that you sent a regular SMS and not an iMessage.
26:03iMessages can only be sent to people who own an Apple device.
26:06So, if the recipient doesn't have one, they're all going to be green.
26:11Another reason your phone might opt for an SMS is that your iPhone isn't connected to the Internet.
26:17iMessages go through the web, and SMS uses a cellular signal.
26:22The jacks you put in your devices have little plastic rings on them that separate different sections.
26:28These sections are called pins, and each of them serves a different purpose.
26:33Each plug will have at least one plastic ring because any plug must be separated into at least two pins.
26:39One of them is there to cancel out any interference, and the other to carry the signal.
26:44If, for example, your headphones have one ring and two sections, they have a mono playback.
26:50They deliver the same sound to both your right and your left ear.
26:53If there are two rings and three sections, then there is a basic one to cancel out interference and the
27:00other two for either ear.
27:01Three rings and four sections mean that you have a set, one basic, one for either of the ears, and
27:08the last one is the microphone pin.
27:12I bet you've never even noticed, but all credit cards, no matter what bank or country they come from, are
27:18the exact same size.
27:19The first ever credit card was issued in 1958 by the Bank of America.
27:25And later, the international standard was established for every issuer around the world to follow.
27:31The standard dictates both the proportions and the thickness.
27:35Whistles can work perfectly fine even if they don't have that ball inside.
27:39Yet, they all have it.
27:41That's because even though there's a sound without the ball, the noise it creates is very flat and not distinguishable
27:48enough.
27:49When you blow, the ball starts moving around inside, creating different pitches and making the noise more noticeable.
27:57Jeans have had those metal rivets ever since they were invented.
28:01Jacob Davis, the man who made the first pair of jeans, added copper rivets to those spots where the pants
28:07were more likely to rip to make them stronger.
28:10Today, they have more of a decorative purpose because they're distinctive and traditional for jeans.
28:16A basketball has little dots all over its surface and they serve as friction points.
28:22It's important for that ball not to slip out of the hands.
28:25There were times when they played basketball with a soccer ball.
28:29The floor was very slippery and it was impossible to play because you'd have to be very careful just to
28:35keep the ball in place.
28:36So, they had to redesign it.
28:38The more points of contact any object has with some surface, the more friction there is and the less likely
28:45it is to slip on the surface.
28:46So, that's how the ball got its dots.
28:50Those holes at the end of the handles aren't just there for you to hang your pans easily.
28:55You can also place your cooking spoon in there while making a meal.
28:58It'll hang right above the pan and the sauce won't spill around.
29:04Make sure to tap off the sauce or food beforehand though so that it doesn't go down the spoon's handle.
29:10You unload the dishwasher and while everything is dry, your plastic containers get all wet once again.
29:17Seems like they never get dry and that's actually true.
29:20The reason for it is the material.
29:22The dishes heat up and cool down slowly, so the remaining water evaporates and dries out easily.
29:28When you take out those plastic containers, they cool down way too fast.
29:33So, the water doesn't dry out of the surface and just stays there.
29:38Another water source is those upside-down cups that collect water on top.
29:43But have you noticed that cups have chips on the bottom?
29:47They serve as a water drain in the dishwasher.
29:49So, yeah, these cups don't accumulate water in the dishwasher.
29:54Take a look at aluminum foil.
29:56One side of it is always shiny and the other one is dull.
30:00When producing the foil, they flatten it with rollers.
30:03It's so thin that the rollers tear it.
30:06So, they take two layers at a time.
30:08So, the sides facing the roller remain shiny and those in the middle stay dull.
30:15We say it all the time, 2 a.m. and 2 p.m. without thinking.
30:19Why such a choice of letters?
30:21It's just Latin, which is still used for many other abbreviations.
30:26A.M. stands for ante meridium, which means before noon.
30:30P.M. stands for post meridium, meaning afternoon.
30:35Same with pounds, which are noted as L.B. from the Latin phrase Libra Pondo.
30:42Most movie theater seats are red and the reason isn't better visibility, but quite the opposite.
30:48In low light conditions, red is the first color that fades away in our eyes.
30:53And that's what we want in a movie theater, to see nothing but the screen.
30:58Also, movie theaters were inspired by fancy Italian opera houses.
31:02So, that's another reason, too.
31:05Have you ever wondered why so many Disney characters wear white gloves?
31:10Well, back when animated movies were black and white,
31:13putting white gloves on characters was a way to make the hands stand out from the rest of the body.
31:19Then, animation evolved, but the gloves stayed as a Disney tradition.
31:23But there are other reasons, too.
31:25Human hands make animal characters more humanized and relatable.
31:29Also, those gloves are way easier to animate, which speeds up the process.
31:35Cats often rub their bodies against your legs, but do you know why they do it?
31:39This way, they transfer their scent to you, marking you as their territory and as their human.
31:45It's also a sign of affection.
31:48By doing this, they show that you're part of their inner circle.
31:53Wonder why it's so hard to swat a fly?
31:56Well, to a fly, we're sloths.
31:59That's because they see things in slow motion compared to us.
32:04Species have a different perception of speed.
32:06The speed we see will be twice as fast for a turtle,
32:09and it will be four times slower for a fly.
32:11Turn a video to 0.25 speed and imagine someone approaching you at this pace.
32:18Well, that's how a fly sees you.
32:20So yeah, it has enough time to escape.
32:25Road signs have different shapes and colors to send different signals to your brain.
32:29Oval shapes are more friendly,
32:31and squared ones are very familiar and secure,
32:34so they're usually regulatory.
32:36Triangles reflect instability, so they're usually warning signs.
32:41And finally, the stop sign has a special octagon shape,
32:44the most unusual and unsettling.
32:47It's supposed to draw your attention to it.
32:49Together with the red color,
32:51this sign stands out the most,
32:53just like it's supposed to.
32:56Some sidewalks have little plates with bumps on them.
32:59We don't pay much attention to them,
33:01but they're very important for visually impaired people.
33:04They signal a slope that then leads to a crosswalk.
33:08Also, there are several patterns that signal different things.
33:12Name the school grades.
33:14A, B, C, D, and F.
33:18No E, but why?
33:20The modern grading system dates back to 1897.
33:24In the beginning, it was all the letters from A to E.
33:28A meant excellent.
33:30B was good.
33:33C was fair.
33:35And D was past.
33:37Below that was an E, or fail,
33:40which was often confused with the opposite.
33:43Excellent.
33:44So soon enough, it was changed.
33:46F, for fail, is way more intuitive.
33:52You know, people come up with the craziest ideas, don't they?
33:56I mean, candies on a stick?
33:58How did we even get there, and why?
34:01And how about the name lollipop?
34:03Well, let's look at some of the history and facts of the popular tree.
34:07Okay, it wasn't called a lollipop to begin with.
34:10We'll get to that name a bit later.
34:12But the initial lollipop-like sweet treat
34:15was most likely invented by people that roamed the Earth thousands of years ago
34:20while still living in caves, no less.
34:23We know that they enjoyed honey and used a stick to collect it from beehives.
34:28Remember, this was way back when people had very few resources
34:31when it came to food or anything else for that matter.
34:34So, since they did not want anything to go to waste,
34:38they probably ended up licking the stick to make sure they ate every single drop of the nectar.
34:44Ancient Egyptians also had a lollipop of their own.
34:47They took various fruits and nuts and glazed them in honey.
34:51Sure, it made the food taste better,
34:53but it also helped with preserving it for longer.
34:56Since it has such a high concentration of sugar,
34:59honey pushes the water out of any harmful cells
35:02that could damage the food and make it go bad faster.
35:05To avoid those sticky honey fingers,
35:08they used a stick for eating these treats too.
35:11Let's fast forward to the 1600s
35:13when sugar became far more available to the general public.
35:17We now know that the English loved boiled sugar candy treats,
35:21and they popped those in the sticks,
35:23making them easier to enjoy.
35:25It's probably during this time when we came up with the term lollipop.
35:30As linguists believe, it basically translates to tongue slap.
35:34How come?
35:35Well, for the word tongue,
35:37they often use the word lolly in Northern England,
35:40and pop means slap.
35:42The lollipop timeline now takes us to 1912,
35:45when a man named Samuel Bourne actually invented a device
35:50that inserted sticks into candy.
35:53It became so popular that Samuel was awarded the keys
35:57to the city of San Francisco in 1916.
36:00However, it was a man named George Smith
36:03who owned a confectionery company
36:05that took credit for inventing the version of the lollipop
36:08which we've come to know and love to this day,
36:11back in 1908.
36:13He even trademarked the name in 1931.
36:16He claimed the name for the treat
36:18came from a famous racehorse named Lollipop.
36:21As you can probably tell by now,
36:24there is still some competition regarding this name.
36:26But what we do know for sure
36:29is that the lollipop became more and more popular
36:31and has remained such ever since.
36:33I mean, some modern companies are capable of producing
36:37up to 3 million of these candies every day,
36:39and the numbers are continuously growing.
36:42The largest lollipop ever created goes back to 2012,
36:47when a Californian candy manufacturer
36:49made a staggering chocolate-flavored one.
36:52It weighed more than 7,000 pounds
36:54and stood proud at nearly 5 feet tall.
36:57And if we take the stick into consideration too,
37:01this huge lollipop was over 11 feet tall.
37:04One of the most famous lollipop brands in the world
37:07is Chupa Chups.
37:08Did you know this brand's logo
37:10has a very famous name behind it?
37:12It was that of none other than Salvador Dali himself,
37:16the famous surrealist artist.
37:18The company approached him in 1969 to design the logo,
37:22and he came up with a distinguishing design
37:25that we know and love,
37:26which has the Chupa Chups name,
37:28incorporated into a brightly colored daisy shape.
37:31The famous painter also came up with the idea
37:34that the logo should be placed on top of the candy
37:37instead of on the side.
37:39Why?
37:39So that you can always see it perfectly
37:41without any of the wrinkles
37:43that are often associated with candy packaging.
37:46Smart, right?
37:48More so, this brand is also associated
37:50with candies we enjoy in the most uncommon places.
37:53A story goes that a Chupa Chups
37:56was the first lollipop to be eaten in space.
37:59That was back in 1995,
38:01when an astronaut brought a Chupa Chups
38:03to the space station,
38:05officially making it the first lollipop
38:07to be consumed in a zero-gravity environment.
38:10Hmm, I wonder if it tasted any different.
38:13There's a Chupa Chups under the sea, too,
38:16but it's not actually what you think.
38:18It's not the easiest thing in the world
38:20to enjoy a lolly underwater, right?
38:22But as they were advancing into an expedition
38:25to the Wardall Sea in the Antarctic Ocean
38:28back in 2000,
38:30a group of scientists stumbled upon
38:32a weird-looking sea sponge.
38:34It had a round-shaped head
38:36and was surprisingly similar to a lollipop.
38:39Obviously, it was given an appropriate name.
38:41The short version was S. Chupa Chups.
38:45If you'll ever search for pictures of these creatures,
38:48they look like underwater lollipops
38:50scattered on the bottom of the seabed.
38:52Now, while we're on the subject of shape,
38:54ever wondered why lollipop sticks
38:56have that square hole featured in the plastic design?
39:00It actually has to do with the manufacturing process.
39:04When produced, the candy is melted into the stick.
39:07This ensures that the head of the lollipop
39:09stays firmly attached to its corresponding stick
39:12so that it doesn't come loose
39:14and end up falling off.
39:15Ooh, what a pity!
39:17Another reason is more of a safety feature.
39:19So, the lollipop stick doesn't become
39:21a choking hazard if swallowed by accident.
39:24Since it does allow air to go through,
39:26there's still some breathing room
39:28should it ever get stuck somewhere...
39:30unfortunate.
39:31These days, the company Tootsie Roll
39:33has become the largest manufacturer of lollipops.
39:37They make over 16 million candies
39:39each and every day.
39:41As for the dum-dum lollipops,
39:43they got their name from their inventor.
39:45He wanted a name that was easy to pronounce
39:48and remember by the younger generation,
39:50the main demographic for the product.
39:53How about the dum-dum mystery flavor?
39:56Is it actually that mysterious?
39:58Nah, it's actually a pretty straightforward recipe.
40:01They make it when one batch of flavor is running out
40:04and the next one is beginning.
40:06So, the flavor comes out of random combinations
40:09of two different tastes,
40:10whatever they may be.
40:12But what does the famous writer Charles Dickens
40:16have to do with the lollipop?
40:18Well, it turns out that in the modern world,
40:20this name first appeared in one of his novels.
40:23That was back in the 1800s.
40:27Lollipops aren't all fun and games.
40:29Some of them are even used to cure people.
40:32They are especially handy for young ones
40:34who find it difficult to deal with traditional versions.
40:37But some of those lollipops are strictly for adults.
40:40If you're a big fan of this sweet treat,
40:43you might want to prepare for a nice celebration
40:45on the 20th of July each year.
40:48That's when people in America
40:49celebrate National Lollipop Day.
40:52It's common for people to give each other lollies
40:55during this day.
40:56Some stores even launch unique lines for this occasion
40:59and also put their best products on display.
41:02The lollipop has some neat world records
41:05attached to it, too.
41:06Like the longest chain of people licking lollipops,
41:09which featured a mind-boggling
41:1112,831 individuals.
41:14They put the event together in Valladolid, Spain,
41:17back in September of 2008.
41:20And for people looking for something fancier,
41:23you should know that the world's most expensive lollipop
41:26comes with a hefty price of over $10,000.
41:30It's not one single lollipop per se,
41:33but a chair made with 60 pounds worth of confectioner's sugar.
41:37We literally have no idea how many lollipops
41:40the world consumes each day in total.
41:42We do know what countries include the biggest fans, though,
41:46and they are Germany, Ireland, Switzerland, Australia, and the UK.
41:51And we don't just call it a lollipop.
41:53There are different names for it,
41:55depending on where you are in the world,
41:57such as a lolly, sucker, or sticky pop, for example.
42:01Hey, I grew up with suckers.
42:03The most common flavor,
42:05often associated with this sweet treat,
42:07is cotton candy.
42:09It's probably because it's way easier to enjoy
42:11than the actual cotton candy,
42:13but you can still appreciate the flavor.
42:15For me, though, nothing beats a cherry sucker.
42:18How about you?
42:20Tell me about your favorite flavor in the comments.
42:23Now, this might shock iPhone fans.
42:26Oh, no!
42:27Calm down, it'll be okay.
42:29Go to Settings, Privacy, Location Services,
42:32scroll down, tap System Services,
42:35and choose Significant Locations.
42:37Your phone knows not only where you live,
42:40but also where you work,
42:42where your favorite supermarket is,
42:44and other places you visit frequently.
42:46If it makes you feel uncomfortable,
42:48just turn it off.
42:50Multitasking doesn't exhaust your battery
42:52as long as the apps in the background
42:54aren't actually working,
42:55like location tracking or any music player.
42:58So, if you don't want to close the apps
43:01on standby for some reason,
43:02it's okay to leave them be.
43:05Cached data consumes a huge amount of precious space,
43:08and buying extra cloud space
43:09is not the only way to retrieve some.
43:12Whenever you see that you're out of memory,
43:14and you've got literally nothing to delete,
43:17check all your messengers.
43:18Even if you deleted the photo from the camera roll,
43:21it's still stored in a cache.
43:23Go to your messenger settings
43:24and delete all the cached files.
43:27There's a sure sign your charger has gone bad.
43:30When you notice it takes more time
43:32to charge your phone, like earlier,
43:34you could go full charged within an hour and a half,
43:36and it now takes more than three hours to do so,
43:39you have to replace the charger.
43:41If you see your phone cable has turned green,
43:44throw it away and replace it with a new one.
43:47The wire inside the cable is made of copper,
43:49and this metal turns green when it corrodes,
43:52just like some statues out there made of it.
43:54If the wire has rusted,
43:56the charger is not safe to use anymore
43:58because it loses its conductive properties
44:01and may even cause an electrical fire.
44:03So whenever you see a greenish tint
44:06on your usually white cable,
44:08toss it without hesitation.
44:10This one doesn't happen that often,
44:12but if you live in a moist or dusty environment,
44:15one day you can see rust on the connecting ends.
44:18Rust often can't be cleaned,
44:19and even if you manage to get rid of it,
44:22it might break the delicate pins on the charging cable.
44:25So it's probably best to replace your charger right away.
44:29Now, charging ports get loose over time,
44:32and once it happens, you start to hold your phone
44:34at a particular angle to charge it.
44:36Take action as soon as you notice it.
44:39Either ask a specialist to fix it or replace the charger.
44:42Now, if your phone won't charge,
44:44it's not necessarily the charger's fault.
44:47The problem can be about the adapter.
44:49The USB ports and adapters can get loose over time.
44:53So if you're sure the cable is fine,
44:55check the adapter.
44:57Also, sometimes the problem may be about the battery.
45:00It may be so that the adapters seem to be fine,
45:04same with the cables,
45:05but the phone just won't charge.
45:07Check the cable jack.
45:09Sometimes it catches a lot of lint,
45:11which results in charging problems.
45:13You can easily clean it with a toothpick.
45:15Don't use a needle or any other metal object, though,
45:18as you may damage the port.
45:20Your phone may malfunction
45:21not only because of battery problems.
45:24Unnecessary data can make it work slower.
45:27So reboot your phone once a week.
45:29Don't overload your device.
45:31Too many pics or documents
45:33don't make it work any faster either.
45:35If you store all the important information in a cloud,
45:38you'll also have access there from any device.
45:42A simple explanation as to why 1% might last a long time
45:46is that the phone has underestimated
45:49the current battery capacity.
45:51Then, when it gets down to what it thinks
45:53should be almost empty, displaying 1%,
45:56it finds that the battery has more capacity left
45:59than it estimated.
46:00There's also a bit of psychology.
46:02When you see that your phone's about to turn off,
46:05it kind of encourages you to plug it in ASAP.
46:09By the way,
46:10modem batteries can't be fully charged or drained.
46:13The last 20% of a battery
46:15takes longer to charge than the rest
46:17because lithium-ion batteries
46:19have a bit of a complex charging profile.
46:22When the battery is low,
46:23the charger supplies a fixed current,
46:26generally the peak current
46:27that the charger or battery combination can handle.
46:30As the voltage increases,
46:32the charger switches over
46:33to a constant voltage profile,
46:35where the voltage is supplied at 4.3 volts or so,
46:38and the current is entirely based
46:40on what the battery will take.
46:42Sleeping with your phone under your pillow
46:44is not a very healthy idea.
46:46Cell phones, tablets,
46:48and other forms of handheld technology
46:50release electromagnetic waves
46:52caused by x-rays,
46:54just as microwaves do,
46:55which may lead to serious health issues.
46:58Even though an adult person's skull
47:00is quite thick,
47:01like mine,
47:02and protects the brain well,
47:04it's best to be on the safe side
47:06and put your phone on the bedside table.
47:09If you accidentally cracked the screen
47:11carrying your phone,
47:12replace it with a new one
47:13as soon as possible.
47:15Yeah, it might not seem a problem
47:17since the touchscreen still works,
47:19but all the grease and dust
47:21will get through the cracks.
47:22It can eventually damage the screen,
47:24so hurry up!
47:26Facial skin is sensitive,
47:27and your phone is almost 7 times
47:30dirtier than a toilet seat.
47:32Talking on the phone
47:33seems like rubbing a toilet seat
47:34against your cheek.
47:36Ew.
47:36So don't press your phone against your face.
47:39You don't want germs, do you?
47:40And maybe wash your hands more often.
47:43Blue light, brightness,
47:45and even font size
47:46can be the reason
47:47why you get a poor night's sleep,
47:49especially if you love
47:51to scroll the feed
47:52until you fall asleep.
47:53Go to Settings
47:54and turn on the blue light filter.
47:57It's called Night Shift
47:58for iPhones,
47:59and there are blue light filter apps
48:01for Androids too.
48:02Also, adjust the brightness
48:03and font size.
48:05Be careful using the phone
48:06on the beach.
48:07Don't leave it in the sun
48:09on your beach towel.
48:10Though it doesn't need sunscreen,
48:11and there's no way
48:12it can have sunburn,
48:13it can still be badly damaged
48:15by scorching rays.
48:17Lithium batteries
48:18are like humans.
48:19Their operating temperature range
48:20is 59 to 95 degrees Fahrenheit.
48:24Now, don't charge your smartphone
48:26if it's over 95 degrees
48:27because it may cause damage
48:29to the battery.
48:30Also, it's bad to charge it
48:32on a cover.
48:33We know cell phones
48:34don't enjoy the heat.
48:35The heat gets trapped inside,
48:37so it can damage your battery.
48:39And never try to cool it off
48:41in a freezer,
48:41as lithium batteries
48:43can't stand cold either.
48:44Boy, they're picky.
48:46Still, remember that some heat
48:48while charging your phone
48:49is completely fine.
48:50The charger uses a transformer
48:52to convert the AC line voltage
48:54from a wall outlet
48:55to the DC voltage
48:57required to charge the battery.
48:59No process would be 100% efficient,
49:01so some amount of electricity
49:03is released as heat.
49:05Excessive heat,
49:06and especially discoloration,
49:07are bad signs
49:09that the charger's circuitry
49:10is beginning to fail.
49:12This may possibly result
49:13in an electric shock
49:15when you unplug the device.
49:17Bzzzt, ow!
49:18Pockets are one of the worst places
49:20to keep your phone.
49:21You can lose it,
49:23accidentally sit on it
49:24and crack the screen,
49:25or, what's way worse,
49:26get radiated.
49:28The phone has a full range of signals
49:30that are not good for our health.
49:32Mobile data, Bluetooth,
49:33Wi-Fi, and NFC
49:35were added to the list.
49:36By the way,
49:37don't use public Wi-Fi
49:39if you don't want to leak
49:40your personal data.
49:41Some people like to jailbreak
49:43their phones
49:43to access more app stores,
49:45not only the official ones.
49:47Well, before doing it,
49:49remember that this procedure
49:50literally eliminates
49:51the safeguard
49:52the manufacturer installed
49:54on your phone.
49:55Plus, unofficial app stores
49:57and apps
49:57can lead to data leaking.
49:59If leaking occurs,
50:01your phone may need
50:02some absorbent undergarments.
50:04Bad, just kidding.
50:05One thing you may
50:06probably never leave home
50:08without is a power bank.
50:10They are much safer
50:12than any public hub.
50:13Make sure the amperage
50:14is correct.
50:15Most modern smartphones
50:17charge at 2.1 amps,
50:18and most power banks
50:20have a range of 2.1 to 2.4 amps,
50:23which is totally okay.
50:24Check if the phone's
50:25not too hot while charging.
50:27The hotter the battery,
50:29the less effective the charging.
