00:00Decades ago, no one would ever imagine keeping a stick in their pocket that could hold hundreds of gigabytes.
00:05We've come a long way since then, and got used to USBs transferring our files from device to device with
00:12ease.
00:13In 2000, two major companies developed and sold the first USB flash drives 1.0,
00:19which snowballed into USB 2.0, 3.0, Type-C, and so on.
00:25Physically, they can endure rough treatment and won't get damaged easily,
00:28especially if you get proper protection.
00:30By design, USBs are almost perfect.
00:34So perfect that you always make the mistake of inserting it in the wrong way.
00:38Admit it, the two square holes are used to help the USB secure its position once it's inside the port.
00:44It's not strong enough to keep it stuck, but strong enough to do its job.
00:50You can protect your USB with proper encryption.
00:53This means that if anyone gets their hands on them, they won't be able to read them.
00:56Encrypted files end up being scrambled into gibberish of a series of letters and numbers
01:02instead of comprehensive words to anyone who tries to read it.
01:06The file is only accessible if someone gets their hands on that USB.
01:10But if you're using certain online services like messaging or emailing,
01:14then encryption is simply not enough.
01:17Sure, the person on the other end can't read the contents of the work, but the hosting website can.
01:24This is where end-to-end encryption comes in.
01:27That means any information that goes in and out is, again, scrambled into gibberish to anyone who is in the
01:33way of your traffic,
01:34including the hosting service.
01:37Cloud storage has taken the world by storm.
01:40You can now save everything that's on your desktop to the internet and access that data across multiple devices.
01:46All you need is an email and password and boom, you're safe and have all your files in one place.
01:54Cloud storage isn't data floating up in the clouds, but, less excitingly, servers that physically store data.
02:00They're like regular computers, just minus the monitors for viewing.
02:04These servers take up a lot of money.
02:07That's why you normally have to pay for their services.
02:09The servers are placed in data centers all around the world where third-party companies manage them.
02:15It's like getting remote access to a computer.
02:18The servers include a master control server, backup server, and a linked supply of servers operating to maintain a good
02:25quality service.
02:27The more money you pay, the better the server your data will be stored in.
02:32In the realm of computers, you just can't delete something to be gone forever.
02:36Whatever file you want to remove is already present in the hard disk as electrical impulses.
02:43And, depending on your gadget, it will be disposed of in a recycle bin or the garbage.
02:48That isn't to say that it isn't still there.
02:51It simply implies that the file has been moved to a different folder from which you can easily recover it.
02:56So, if you're worried about accidentally deleting a crucial document you've been working on for weeks, don't panic.
03:02It's not gone for good.
03:03But if your device breaks, then all your data is lost.
03:07If you own a device that has Windows 10, then you've probably been shutting down thinking that your computer or
03:13laptop is completely off.
03:16This is not the case.
03:17Windows 10 doesn't actually shut down, but goes into a state of hibernation.
03:21It keeps your app saved for you to recover.
03:24The proper way to shut it down is by resetting it.
03:28Windows operating system is known for being user-friendly with all the commands displayed in front of you.
03:34But for computer whiz kids, know that you can open the search bar and type CMD for the command prompt.
03:41It looks just like a bunch of random characters, but this is where you can achieve a lot with your
03:46device.
03:48If you don't like the black window, you can always change the color of your suiting.
03:53Once you launch the command prompt window, right-click on the title bar and then on Properties.
03:59Another window will open which has the option of choosing colors.
04:03You can pick the colors you want for the background and text or fix the opacity for the CMD window.
04:10This is easy mode.
04:12The real work is typing commands in the window.
04:14If you want to look for all your drivers on your Windows 10 device, then type in this command in
04:20the window.
04:21Don't forget to add spaces.
04:23The list of servers will magically pop up on your screen.
04:26This is a good way to get to the bottom of your issue, instead of searching for them manually.
04:31You can also hide specific folders on your computer through the command prompt by typing this command and pressing Enter.
04:39Of course, you'll have to type in the folder you want to hide, and poof, it's gone.
04:45The non-tech way of doing this is by opening the Properties pane in the folder and clicking on the
04:50checkbox that shows Hidden.
04:54While this is indeed the easy way of hiding your folders, it's not the most effective.
04:59You can simply write Show Hidden Files and Folders, and every checkbox you check will be visible again.
05:07The command prompt isn't all about business.
05:10You can try playing a game there to pass the time.
05:13Don't expect a AAA kind with realistic graphics and epic gameplay.
05:17Type this command and you'll be transported into the game via text.
05:22This game will allow you to create characters and engage in this imaginary world.
05:28Google Chrome is one of the most popular browsers on the net, but you can also play a text-based
05:34game there, just like in the command prompt.
05:37First press Ctrl plus Shift plus J to open the console.
05:42Then type Text Adventure into the search box.
05:45Don't freak out, you just opened the sort of a back end of the page.
05:50Next, click on the box that says Console.
05:53You'll be greeted with a text that will ask you if you want to play a game.
05:57Type Yes, and you'll instantly begin.
06:00They'll give you some basic commands which are easy to follow and an opening premise of the journey.
06:06If you're looking for something a little more contemporary, then get ready to play some solitaire.
06:11No worries, you don't have to type some command to play it.
06:14All you need to do is type Solitaire in the search bar, and you're there.
06:19You can play the exciting game of Solitaire in your web browser.
06:23And when you get bored, you can play the classic game Pac-Man.
06:28If you're from the generation of the classic bulky phones, then this next game will bring back all those memories
06:34of your childhood.
06:35Open Google and type Snake, and there you go.
06:40When the internet is down, you can play the dinosaur game in your browser window while you're impatiently waiting for
06:46the Wi-Fi to come back.
06:47This game is very simple.
06:49After pressing Enter, you just have to hit the space bar to jump over obstacles.
06:54And at a certain point, you'll have the option to duck down, which will make it even more challenging.
06:59Even without Wi-Fi, you can still have a good time.
07:02You can pause the game whenever you want by pressing the Alt key or F11.
07:07You can just click on your screen to continue the game at any time.
07:11Windows 11 has some cool hidden features that are very useful, like adjusting the volume for each individual app.
07:19You can go to Settings and click on System.
07:22Hit the Sound section.
07:24This will bring you to all the sound levels and the master switch.
07:29Copy-pasting is so essential to our everyday workflow that Windows 11 decide to take it to a whole other
07:35level with Clipboard History.
07:38This option allows you to save your copied texts in one designated area, which you can access any time.
07:46And the good news is that this option is also available on Windows 10.
07:50Just click on the Windows key, plus V, and you're good to go.
07:55If you have too many windows opened on Windows 11, you can grab the window that you want to keep
08:00and shake it.
08:01It will minimize all the remaining windows in the background so that you can have a pleasant, productive workflow.
08:07Oh wait, it's happening now!
08:10The button on the top of your baseball cap is there purely for aesthetic purposes.
08:15By the way, this little thing has a name.
08:17Professionals call it a Squacho.
08:20Its initial function was to hold the four panels of the cap together.
08:24As hat-making improved, the panels stopped needing it to hold together, and Squacho was removed.
08:30But hats didn't look the same without it.
08:32Soon after, the Squacho returned due to popular demand.
08:37Originally, high-heeled shoes weren't intended for galas and proms.
08:41Back in the 10th century, horse riding was pretty tough with flat-soled shoes,
08:45and many riders' feet would constantly fall out of the stirrups.
08:49Higher heels helped deal with that problem.
08:52The grip was much firmer with them, and they grew in popularity.
08:55It wasn't long before they became a fashion accessory to match stylish outfits.
09:00Notable people wouldn't want to be seen without them.
09:03Riding a horse with fancy heels was the equivalent of owning a luxurious sports car.
09:08Even though heels were worn mainly by men at the start,
09:11ladies picked up on the iconic trend in the 17th century.
09:14It's been one of the biggest ever since.
09:18In ancient Rome, salt was so precious that people even called it white gold.
09:23With scorching heat and no fridges, its purpose was to preserve food, mainly meat and fish.
09:29As a bonus, it made everything tastier.
09:33Sal, which is salt in Latin, was used instead of money to pay salaries.
09:37Here is where the word salary originated.
09:41Rice is the oldest cultivated food in human history.
09:45Its origins as wild grass started in a small valley around 15,000 years ago in Southeast Asia.
09:52Today, it's served globally as a staple diet and popular ingredient to 3.5 billion people.
10:00It would be difficult to imagine a world without video calls you use through your phone camera or laptop.
10:06The technology has helped game-changing innovations like working from home.
10:10Still, video calls' original purpose is far from how we use them today.
10:15The technology was introduced to confirm if the coffee was still in a pot.
10:20In 1993, researchers at the University of Cambridge found it frustrating when they took a break to get a cup
10:26of coffee,
10:27only to find that the pot was empty.
10:29So, they invented a device to monitor it and hooked up a camera that provided their computer with a live
10:35stream of the coffee pot.
10:37Thanks to these researchers, we can work in pajamas now.
10:41We know Albert Einstein for various achievements, but there's something he co-invented that goes overlooked.
10:48Together with his student, he invented a modified refrigerator.
10:52It's not like the ones we use today.
10:54In the 1920s, fridges weren't quite as safe as they produced poisonous gases.
10:59He wanted to create a safer version that didn't require electricity,
11:03without moving parts and only needed a heat source to operate.
11:07Unfortunately, there wasn't enough funding,
11:09so the project dried up.
11:11Later, in the 1950s, electric fridges became popular.
11:15But in 2008, engineers from Oxford University revived this retro design.
11:20They're still working on it, but once they finish,
11:23the Einstein fridge will come in handy for rural areas without power
11:26and people who want to live off the grid.
11:30That random, QWERTY design doesn't make things easier.
11:33In the 1870s, Christopher Scholz invented a layout that ensured typing was twice as fast.
11:39But with commonly used letters next to each other, it was a bit too fast,
11:43and the machines constantly jammed.
11:46So, he then developed the QWERTY design.
11:48It forced typists to adopt a pecking style.
11:52This way, they would search for a letter and slowly type with their index fingers.
11:56The keyboards remain unchanged even today, and people all over the world have somehow adapted to them.
12:04The plastic end of your shoelace is an aglet, and people have used it since ancient Rome.
12:10Sure thing, they had no plastic back then, so those aglets were made of stone, glass, or even metal.
12:16Extra-wealthy people could accessorize their shoes with precious metals, like brass or silver.
12:23What came first, the TV or the remote control?
12:26The technology that functions in the remote is older by several decades.
12:31In 1898, Nikola Tesla created a machine to control mechanical devices with radio waves.
12:37Initially, he tried selling the idea of a radio waves device operating I.O. through remote control boats.
12:44But the potential buyers were not interested.
12:47He was way ahead of his time, as remote controls were finally used with televisions in 1956.
12:53As engineer Percy Spencer initially invented something brilliant in 1945,
12:58he was working on a new vacuum tube, the Magnetron, which was used with early radar systems.
13:04While working on the project, he found that the chocolate in his pocket had melted.
13:09Realizing the heating potential of the Magnetron, he used it on corn kernels, which turned into popcorn.
13:15Then, he tried testing it with eggs, but things got a bit messy.
13:19So once the yolk was washed away, he built a metal box, keeping the energy within.
13:24And the first microwave oven was built.
13:29In 1733, a duke in England requested William Kent, an architect, to make a traveling device for his kids.
13:36William accepted and built the first ever stroller.
13:39But nobody had to push it.
13:41Instead of handles, it was built like a carriage and pulled by a goat or a small pony.
13:46Only a few were made as it was pricey.
13:49More than 100 years later, in 1848,
13:51the first stroller with push handles became available and more affordable.
13:58Police are often associated with donuts, and there is actually a reason why.
14:02During the 1950s in the USA, police officers that worked night shifts
14:06found it hard to locate anywhere open for a midnight snack.
14:10Donut shops at this time were family-owned.
14:13They were working hard throughout the night, providing fresh donuts for the coming day.
14:16The shops were vulnerable at night, becoming the perfect relationship.
14:20Nourishment for the police and extra protection for the shops.
14:25Popping bubble wrap is an excellent source of relaxation,
14:28and it's also helpful with delicate packages.
14:32In 1957, two engineers glued together two shower curtains,
14:36trapping the air bubbles between.
14:38This is how the first bubble wrap was made.
14:41The result they were looking for was a sort of textured wallpaper.
14:44Still, it didn't go well on the market.
14:47Sometime later, they tried to sell it as insulation for greenhouses,
14:51and once again, they failed.
14:53Everything changed in 1960 when IBM needed to ship delicate computer parts.
14:59The bubble wrap was perfect, and they continued to collaborate.
15:03Using maps with your phone has become a far easier way to navigate,
15:07but the old-fashioned handheld maps were once the only option,
15:11creating a competitive industry.
15:13So much so, that mapmakers would draw in phantom settlements to avoid rivals stealing from them.
15:19These fake towns were called a copyright trap.
15:23However, one of these fake settlements became real.
15:26Aglo in New York was drawn into a map by General Drafting Co.
15:31Another competing mapmaker had also included this town on their own,
15:35and the copyright trap was sprung.
15:37But in court, they found that in 1950, a general store had actually been built there.
15:42And the owner assumed that Aglo was a real area based on the map,
15:46so he named the shop after it.
15:48So, there was no violation found,
15:50as technically, Aglo was real, thanks to that general store.
15:55In 1943, Vesta Stout from Illinois was working with securing parcels.
16:00She was disappointed with the poor paper tape, as it would fall apart when wet.
16:05So, she asked her boss to try to make waterproof tape.
16:08Her request was ignored, but she wrote a letter to President Roosevelt with an idea of how to make a
16:14better tape.
16:15Not only did she explain her concept, but she also provided it with detailed designs.
16:20He approved the idea and ordered the changes.
16:23The new tape was so helpful for freight transport that everyone wanted it,
16:27and they started selling it at hardware stores.
16:30In the 1950s, many people would wrap air ducts, and it was then deceptively named duct tape.
16:37Still, the adhesive on the sticky side wasn't suitable for cold and hot temperatures,
16:41which caused the tape to fall off.
16:43Despite this, people continued to use that tape for almost everything else.
16:49Have you ever wondered why things are the way they are?
16:52Like, why are there holes in a takeout box?
16:54Don't worry, you're about to find out.
17:01Beanies with all those fluffy pom-poms are easily the most important accessories of wintertime.
17:08Turns out the real reason why they or other hats have pom-poms
17:12was not to make a fashion statement in the past.
17:14One of the theories says that they were there to provide safety.
17:18French sailors used to wear hats with pom-poms so they wouldn't hit their heads on the walls
17:22or low ceilings and hurt themselves if they lost their balance in a rough sea.
17:26So it wouldn't be wrong to call pom-poms head bumpers.
17:30Ever notice those extra eyelets hiking boots have on their sides?
17:34One thing is for sure.
17:35Even though it kind of makes sense,
17:37they're not there to provide ventilation for your feet so that they don't smell.
17:41They're there to prevent your shoes from moving
17:44and causing you to slip and fall while you're hiking,
17:48climbing,
17:51or descending a hill.
17:52When you're going on your next adventure,
17:55make sure to tie your laces through them to tighten your boots for a better fit.
18:01You're at a barbecue party with your friends.
18:03The host serves cold drinks and long neck bottles to everyone.
18:07You think to yourself,
18:08why do bottles have long necks anyway?
18:11There are two reasons for that.
18:12The first one is to reduce the cost of packaging.
18:16The narrower the neck is,
18:17the smaller cap you need.
18:19And the second reason is to make sure that your drink stays cool longer.
18:23When you hold the bottle from its neck,
18:25not its body,
18:26the heat coming from your hand won't warm up the rest of your drink.
18:35The color of plastic tags on bread packages
18:38indicates which day of the week the bread was baked.
18:41Even though some companies have their own color codes,
18:43it generally goes like this.
18:45Monday,
18:46blue.
18:47Tuesday,
18:48green.
18:48Thursday,
18:49red.
18:50Friday,
18:51white.
18:52And Saturday,
18:53yellow.
18:57So pick accordingly to get the freshest bread.
19:01You're feeling too lazy to cook dinner,
19:03so you go to your favorite restaurant to order takeout.
19:06You come home feeling excited that you're about to have a delicious meal.
19:10You open the takeout box only to find out that your food became soggy
19:14because of the moisture built up inside of it.
19:17Well,
19:17this secret purpose is going to help you prevent that from happening ever again.
19:21Notice the perforated tabs in the corners of the container's lid?
19:24You need to push them down to allow the steam to escape from the holes.
19:29If you have a hot meal, that is.
19:36If you're one of those lucky people who have a dishwasher at home,
19:39you're going to feel even luckier once you learn what else you can wash in it.
19:43Aside from making your dishes clean and shiny,
19:46it can also clean up your makeup brushes for you.
19:48Just place them inside the silverware tray
19:51to remove all the dirt and excess product that built up amongst the bristles.
19:57You went to the farmer's market and bought some fresh fruits and vegetables.
20:02You want to wash the dirt off them,
20:04especially potatoes,
20:05before placing everything in the fridge.
20:07Don't waste your time washing them all one by one.
20:10Place them in your dishwasher
20:11and set it to the rinsing cycle with cold water.
20:14Don't use detergent for this though.
20:18Are you one of the many people
20:20who use the drawer under their oven or stove as storage?
20:24Sorry to inform you,
20:25but storing skillets, cookie sheets, and muffin pans is not their purpose.
20:29It's called a warming drawer
20:31and it's meant to keep your cooked dishes warm and delicious.
20:34So if your guests are running late,
20:36just put that casserole you've made in it until they arrive.
20:41Keep in mind that not all oven models have this feature.
20:44Some drawers are for broiling
20:46and some can indeed be used as storage.
20:49Check with the manual to make sure what yours is.
20:53Oranges, lemons, and avocados come in mesh bags most of the time.
20:57When you go back home from the grocery store,
21:00you probably throw those into the trash, don't you?
21:02But did you know that you can also use them as a pot scrubber?
21:05You just need to tie them up.
21:07Then you can get to cleaning those dirty dishes, pots, and pans.
21:13You can even turn them into single-use scrubbers for other kitchen appliances or your sink.
21:20If you're at a store looking for new hangers to organize your closet,
21:24we suggest you buy the ones made of cedar wood instead of plastic ones.
21:29First of all, cedar wood acts as a natural repellent.
21:34Pests like moths, fleas, lice, silverfish, ants, gnats, and ticks
21:39won't come near your clothes and closet if you use them.
21:42The second reason why you should invest in them
21:45is that they absorb unwanted odors from your clothes as well as moisture.
21:49And this feature helps prevent mold,
21:51so you can wear your favorite dress or suit for longer.
21:56It's that time of week again, Taco Tuesday.
21:59You invite a couple of friends over to enjoy some homemade tacos,
22:02but even though you have the recipe for making tortillas,
22:05you don't know how to give them that perfect taco shell shape.
22:08Well, this hidden use might help.
22:11If you have a muffin tray at home, then you have all you need.
22:18Just flip it upside down and place the small tortillas in between the cups.
22:24Bon appétit!
22:29If you love sewing and making your own clothes,
22:32then you must be used to using those tomato pin cushions,
22:35which almost always come with a small strawberry tassel.
22:38But why is it there?
22:40First of all, you can push the needle you're currently using
22:43or your favorite one in there
22:45so that you don't need to search for it amongst the other needles all the time.
22:48And secondly, it's filled with emery,
22:50which will help clean and sharpen your needles once they go in there.
22:57Are you a team ketchup or team mayo?
23:00Ketchup fans must have noticed the number 57 on those Heinz ketchup bottles.
23:04That number is placed where it is on the bottle for a very specific reason.
23:10You must have struggled with getting ketchup out of the bottle at least once in your life.
23:15And at that moment, you probably tried shaking it
23:17until the right amount of ketchup fell onto your plate, right?
23:21Well, no need to do that anymore.
23:23Just firmly tap on the spot where 57 is written on the bottleneck.
23:27And you can get ketchup out of the bottle way quicker.
23:35You might have noticed that there are two holes in an oil can
23:39where you are filling it up or pouring it.
23:41And you maybe thought to yourself,
23:43that must be there to make it easier for me to pour it into smaller containers.
23:47But that's not the case.
23:49That hole is there to prevent oil from spilling all over or glugging, so to say.
23:53So you need to uncap it before you pour oil from the larger hole
23:58to prevent wasting it or having to clean everywhere.
24:01Have you ever taken classes to improve your typing speed on a keyboard?
24:05If your answer is yes,
24:06then you might be disappointed to learn that keyboard manufacturers
24:09most likely wanted to slow you down.
24:11A popular theory says that's why the letters on a keyboard are arranged randomly
24:16and not in alphabetical order.
24:18The reason for that goes all the way back to typewriters.
24:21Their keys used to be arranged in alphabetical order,
24:25which allowed people to write really fast.
24:27And because of that, the keys would jam and tangle up easily.
24:31And they wanted to avoid that.
24:33That's how we ended up having the QWERTY keyboards we have today.
24:38Here's a bonus hidden feature for you before you leave.
24:43The clock app on your iPhone
24:45shows you what time it is on the little screen icon as well.
24:523, 2, 1.
24:55Bam!
24:56Now instead of enjoying the new movie,
24:58you will enjoy cleaning your microwave after the popcorn apocalypse.
25:01And all this because you trusted the popcorn button too much.
25:06It turns out, many of those buttons are just timers
25:09and not professional chefs hidden in the microwave.
25:12Different types of popcorn,
25:13and maybe even different batches of your favorite one,
25:16have different popping times.
25:18It depends on the weight and humidity of the corn,
25:21and there's no magical cooking regime that would work for them all.
25:25If you don't give your popcorn enough time to pop
25:28because you rely on the button,
25:29it will be undercooked and full of kernels.
25:32If you let it pop for too long,
25:34it'll burn,
25:35and the smell will be with you for longer than you'd want it to.
25:39Some newer, fancy microwave models
25:41come with humidity sensors
25:43that take all the factors into account
25:45and can actually figure out how to cook your popcorn.
25:49All you have to do is touch a special pan.
25:51Check your microwave manual to see if it can do the trick.
25:55If that's not your case,
25:57you need to follow the instructions on the popcorn bed.
26:00Most of them say,
26:01do not use the popcorn button.
26:04A microwave that works on 700 watts
26:07is slower than that with 1,000 watts of power.
26:10And even when you did the math
26:12or follow the manual to a tee,
26:14don't leave your popcorn unattended.
26:16Give it those several minutes of your life
26:18and stay nearby to make sure all is going well.
26:22Listen to the popping symphony.
26:24When it slows down to 2 to 3 seconds between pops,
26:28turn it off.
26:29If you overcook it,
26:30it can lead to scorching.
26:32And even when you follow all the rules,
26:35you can't just blame it all on the microwave.
26:37Check your popcorn's best buy date.
26:40Keep your microwave clean.
26:41Always remove the plastic overwrap and unfold the paper bag.
26:45Now you should be fine.
26:50If you want to experiment more with your microwave,
26:53you can try drying herbs in it.
26:55Sandwich some fresh herbs between two paper towels
26:58and microwave them in 30-second intervals
27:01until they're as dry as you want them to be.
27:03You can also toast nuts the same way,
27:05in 30-second intervals,
27:07in chopped form,
27:08in a single layer on a plate.
27:10Your microwave can also help you peel garlic easily.
27:14Put the whole head in for around 20 seconds,
27:17and the cloves should slip out of the peels
27:18without any problems or smelly fingers.
27:24A cube of ice is not something you'd expect to be microwaved,
27:28but this trick has taken TikTok by storm.
27:31One vlogger tried heating salmon and rice in the microwave
27:34with an ice cube and a piece of parchment paper on top.
27:38She also added other ingredients,
27:40like kimchi,
27:41mayo,
27:42soy sauce,
27:43avocado,
27:44and dried seaweed.
27:46Adding water to reheated ice isn't new,
27:48but ice is something rather sensational.
27:52A chef instructor explained that an ice cube
27:55gives something for the microwave to heat,
27:57and the steam diffuses all the way through the food.
28:00It helps prevent that annoying situation
28:02when only half your meal is properly warmed up.
28:05The parchment paper lid also helps to keep the heat in.
28:09The steam moves up,
28:10hits the paper,
28:11and the hot liquid goes down to reheat the food.
28:14It takes a while for an ice cube to fully melt in the microwave.
28:17The water molecules in it are locked
28:20and held together by strong hydrogen bonds.
28:23So,
28:23it takes a lot of energy to break those bonds.
28:29Did you know that microwaving your tea
28:32is the best and healthiest way to brew it?
28:35Australian scientists proved that this way
28:38you can squeeze out all the good stuff in your cuppa.
28:41So all you need to do
28:42is drop a tea bag in a cup of freshly boiled water
28:46for half a minute.
28:47Then,
28:47you need to place it in their microwave
28:49with the leaf bag still inside,
28:51and keep it brewing for one minute at 500 watts.
28:55Finally,
28:56you need to fish out the tea bag
28:57and enjoy your drink.
28:59A cup of green or white tea
29:01has more antioxidant benefits
29:03than a portion of broccoli,
29:05spinach,
29:05carrots,
29:06or strawberries.
29:07And now,
29:08all the benefits are yours.
29:11Brewing tea in a microwave
29:12is a great alternative to an electric kettle.
29:15That kitchen gadget most American households don't have.
29:18Yet,
29:19they're super popular in the UK.
29:21The reason is simply the difference in efficiency.
29:24Most American homes run on around 100 volts.
29:28And the UK and many other countries
29:30use between 220 and 240.
29:33The lower the voltage,
29:35the slower the speed that the appliance has.
29:37So,
29:38if we do some simple math,
29:41it will show that it would take the same kettle
29:43around a minute and a half longer
29:45to get to boiling temperature in the US
29:48than in the UK.
29:52The microwave oven that made the lives of so many people easier
29:56was invented by accident in the 1940s.
29:59Its creator,
30:00Percy Spencer,
30:01was trying to design a more efficient
30:03and effective way
30:04to mass-produce radar magnetrons.
30:07It's a kind of electric whistle
30:09that creates vibrating electromagnetic waves.
30:12Spencer was testing one of his magnetrons
30:15when he put his hand in his pocket
30:17to have a snack.
30:18The peanut cluster bar he had inside
30:20had melted
30:21and turned into a gooey mess.
30:23So,
30:24he couldn't enjoy his snack,
30:25but he realized that something unusual
30:28had just happened.
30:29Spencer ran another test with the magnetron,
30:32this time on an egg under a tube.
30:34The egg blew up just moments later.
30:37The following day,
30:38he popped corn kernels with the new invention.
30:40And that's how the first prototype
30:42of the microwave was born.
30:44It's one of the several inventions
30:46from the 40s we still use and love today.
30:52The official birth of the mobile phone concept
30:55is 1947.
30:58It wasn't a flip phone
30:59that everyone secretly had in their pockets.
31:02Back then,
31:03AT&T proposed to the Federal Communications Commission
31:06to dish out a ton of radio spectrum frequencies
31:09to make the dream
31:10of widespread mobile telephone service a reality.
31:14Bell Laboratories introduced the idea
31:16of cellular communications the same year.
31:19The FCC didn't support the idea
31:21and limited the number of frequencies
31:23to 23 phone conversations possible
31:26at the same time in the same service area.
31:29The first call on a portable cell phone
31:31was only made in 1973.
31:34It was a prototype weighing 28 ounces.
31:40Back in the 1920s,
31:42some genius engineers
31:43were already cooking up the idea
31:45of color television.
31:47But only in the early 1940s
31:49did CBS and engineer Peter Goldmark
31:51create a system that beamed images
31:53in all three primary colors.
31:56By the 50s,
31:57color TV had already settled
31:59in the living rooms of families in the West.
32:05You wouldn't be able to spray your hair
32:07against all elements
32:08or paint a mural easily
32:09without aerosol spray can technology.
32:13It was an invention
32:14of the Department of Agriculture researchers.
32:16They created the aerosol
32:18to spray dangerous bugs.
32:20Spray cans,
32:21mostly with insecticides,
32:23became available to the public shortly after.
32:25The invention was later perfected
32:27by an American inventor and engineer
32:29who created a crimp-on valve.
32:32His invention was made of lightweight aluminum.
32:35It made the cans cheap and practical
32:37to dispense liquids,
32:38foams,
32:39powders,
32:39and creams.
32:44In the 1940s,
32:46Swiss engineer George de Mistral
32:47went for a stroll in the woods with his dog.
32:50Suddenly,
32:51his clothes
32:52and his dog's fur
32:53turned into a magnet
32:54for hundreds of annoying cockle burrs.
32:57George got curious
32:58and whipped out a microscope
33:00to check out these burrs up close
33:01to find out their success secret.
33:04He knew this tech could be useful.
33:07So,
33:07the engineer discovered
33:09that they had tiny hooks
33:10that looked like a monster's spiky fangs.
33:13Those hooks could latch onto anything
33:16with a loop,
33:17clothing fiber,
33:18animal fur,
33:18or even human hair.
33:21De Mistral realized
33:22he could mimic this burr magic,
33:24and that's how Velcro was born.
33:26All right.
33:27Welcome.
