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!
08:09Most kitchen shears have metal plier-like teeth in the middle, between the handle grips.
08:14They can help you crack nuts, crab shells, and release other tough products.
08:20You can also open jars and bottles, or remove herb stems with their help.
08:25You can keep your cold meals cold and your food fresh by making a DIY ice pack.
08:31Take a sponge and fill it with water.
08:33Then put it in a plastic bag and leave it in the freezer.
08:37Once the sponge is frozen, it'll stay this way for a long time.
08:41Keep in mind that you should use a watertight bag and a fresh sponge.
08:46If you turn over a Tupperware container, you'll see some symbols.
08:50They'll inform you if you can put the container in the dishwasher, if it can be microwaved or frozen.
08:56You may even find out how you can recycle the thing.
09:00Staplers actually have two modes, not just one.
09:03There's a metal plate on the lower part of the device, which helps bend the staples inward after they've pierced
09:10the paper.
09:10What many people don't know is that you can turn this plate around to switch from the staple mode to
09:17the pinning one.
09:18The pinning setting is for temporary fastening.
09:21The staples bend outward, making them easier to remove when necessary and damaging the paper less, too.
09:29When you take a sip from a coffee cup closed with a lid, the air pressure inside the cup drops.
09:35That's why the air from the outside tries to push into the cup.
09:39The tiny hole on the lid allows some air to enter this way, and the liquid can go out of
09:45the main hole more smoothly.
09:48It's often hard to figure out how much detergent you need to clean your laundry well, but not go overboard.
09:54Pay attention to the cap of your detergent.
09:57It usually has a marker indicating how much product you need to add to your laundry.
10:02Or there might be an instruction on the bottle.
10:04It'll let you know how to measure the detergent.
10:08You can use most screwdrivers together with a wrench to create more torque.
10:13Just place the wrench over the handle of the screwdriver.
10:16This way, you'll need to apply a lot less force than before.
10:20You'll also be able to get to hard-to-reach areas more easily.
10:24The hole in a ruler can be useful if you want to hang the device on a hook.
10:29You can also place a pencil tip in this hole if you need to draw a perfect circle.
10:35Coffee stirring sticks have holes in them because those help reduce the resistance from your drink.
10:41This way, they can stir sugar much more effectively.
10:45Such a design also makes these plastic sticks tougher and prevents them from bending in hot water.
10:51And since stirring sticks are partially hollow, less plastic is used during their production.
10:57Some boxes of chocolates have little dents in between the holes for candies.
11:02If you push such a dent, the chocolates surrounding it will pop out of their compartments.
11:08The small bumps on the F and J keys on the keyboard help people find the right keys without looking
11:14down.
11:15It's especially convenient for those who use touch typing.
11:19The rumble strips on the sides of the road are placed there to alert drivers who doze off behind the
11:25wheel.
11:25When their tires move over these strips, the noise and vibration work like an alarm clock.
11:32The black grate on a microwave is called a Faraday shield.
11:37It contains the electromagnetic energy inside the oven and protects the exterior from radiation.
11:43The grate also speeds up the heating process.
11:46Bottles have long necks so that your drink stays cool longer.
11:51Hold the neck, not the bottle itself, and your drink won't warm up.
11:55Dimples on the surface of a golf ball increase its lift and reduce air resistance.
12:00It means that the ball can go further.
12:03The dimples don't have to be spherical.
12:05They can be hexagonal or have any other shape.
12:09There's a tab on the bottom of your rearview mirror.
12:12If you push it back during nighttime driving, the headlights of the car moving behind yours won't be so blinding.
12:19If you're driving during the day, pull the tab forward.
12:23You can peel an orange more effectively if you cut into the peel at the top and bottom first.
12:29Then make a slit on one side and just pull the peel open.
12:34Headrests in cars are detachable.
12:36You can use one to break the windows if you get stuck in your vehicle.
12:40But by smashing the glass, you can easily hurt yourself.
12:44So, try sliding one of the prongs in between the windowpane and the door.
12:49Then pull the headrest towards yourself.
12:51The window will shatter.
12:53But, hey, I'd try the door lock first.
12:57Solo cups used at barbecue parties can help you measure liquids.
13:01The bottom line equals one ounce.
13:03The second line means you've poured five ounces.
13:06And the third line means 12 ounces.
13:10Sneakers were originally invented for basketball players.
13:13And since they needed to lace their shoes in the most comfortable way, side holes were invented.
13:19Those helped players lace their sneakers in any way they liked.
13:22And they accommodate anyone's foot.
13:25Little buttons on your jeans are called rivets.
13:29They were originally placed there to prevent the seams from ripping.
13:32In the past, mostly miners and other workers wore jeans.
13:37That's why this item of clothing had to be particularly durable.
13:40And even though these days, jeans aren't under such stress, the tradition of using rivets still remains.
13:48A big toothy spoon comes in handy when you need to pull your spaghetti out of the pot.
13:53And the hole in the middle of this spoon can help you measure portions.
13:57One portion equals as many dry noodles as you can fit into the hole.
14:03Sometimes, pre-rinsing dishes may lead to your dishwasher cleaning them worse than it could.
14:09Special sensors inside modern dishwashers can perceive how dirty your plates are.
14:14And after that, they send a controlled jet of water to wash all that stuff off.
14:19The only thing you're actually supposed to do is remove solid food from your plates and stack them up properly.
14:26Ribbed ketchup containers that they give you at fast food restaurants can get a bit bigger.
14:30Just pull the ribs outward and your container will house much more sauce.
14:36While using a plunger on a clogged kitchen sink or toilet, make sure you've got the right tool.
14:42If it has a standard bowl-shaped rubber head, it's perfect for flat surfaces such as a sink or a
14:48tub.
14:48But the one designed for toilet pipes has a narrower head.
14:54The hole near the rim of your bathroom sink is there to prevent overflows.
14:58Thanks to it, all excess water goes into the siphon.
15:02Plus, it helps your sink drain faster.
15:05The hole gives the air gathered in the siphon somewhere to escape.
15:10The hole in a lollipop stick can save your life.
15:13If the stick gets stuck in someone's mouth, the hole will prevent this person from choking.
15:19But the original reason for it is to simply not let the candy run off the stick.
15:24During production, the liquid treat is poured on top of the stick.
15:28The stick is hollow inside, so the candy gets inside it from both the top and the side, through that
15:34exact hole.
15:35And when it gets solid, it keeps perfectly on the plastic tube.
15:40Most padlocks have a tiny hole on the bottom.
15:43It's needed to drain water from the lock and avoid corrosion.
15:47By the way, it's the best place to lubricate a padlock.
15:51Just put a drop of oil there, and the key will turn much easier.
15:55If you don't see a hole on the bottom, the lock is supposed to be used inside.
16:01Instead of opening a banana at the stem, turn it upside down and peel it from the bottom.
16:06It opens much more easily this way.
16:10A utility knife can serve you much longer than you might think.
16:14Look at the blade carefully.
16:15It's made of parallel sections.
16:18Once the knife gets blunt, you should break off the top section.
16:22You can do it with the help of the cap you'll find at the bottom of the instrument.
16:25In no time, you'll have a sharp blade again.
16:29The stripes on headphone jacks keep the wires insulated from one another.
16:33One stripe means the headset has a mono signal.
16:37Two stripes indicate you'll have stereo sound.
16:40And three stripes means the headset also has a built-in microphone.
16:44You can usually find some silica gel in bags, shoes, and many other things you buy.
16:50This gel absorbs excess moisture.
16:53Don't throw it away.
16:54Every time your shoes get wet, put some packets of silica gel inside them.
16:58It's very convenient to use bread tags to organize your cords.
17:03Just take a bread tag and several cords and clip them together.
17:07You can also write notes on these tags and use them as reminders.
17:13Think you're ready to see the world in a whole new way?
17:16I hope so, because I'm about to blow your mind.
17:20Have you ever noticed those plastic lines along the side of your phone?
17:24They're the oddly spaced stripes that seem to have no purpose.
17:27In reality, though, they're probably your phone's most important feature.
17:32Because without them, your device would be little more than a smart paperweight.
17:36They are antenna lines, allowing your phone to remain wireless.
17:42Electromagnetic waves carrying phone, Bluetooth, and Wi-Fi signals cannot pass through metal,
17:47which makes up most of the phone's outer case.
17:49And the glass panel up front also slows those waves down.
17:53It's like there's a bouncer at the door, refusing to let most signals in or out of the phone.
17:58Hey, I've been to that nightclub.
18:00Anyway, that means no phone calls, no text, and no late-night delivery
18:05when you have nothing in the fridge except one egg and something that might have once been lasagna.
18:09Those little strips of plastic allow the same electromagnetic waves to come and go as they please.
18:15This is why you can call a friend, order a ride, or play an online matching game until 3 in
18:20the morning.
18:21Hey, don't you have to get up early for work?
18:23When you do finally stumble out of bed, make sure you're using this next item correctly to avoid a potentially
18:30upsetting situation.
18:32The zipper, originally patented as the clasp locker in 1851, didn't become widely used until the 1930s.
18:40Now they're on everything, from bags to jackets to jeans.
18:44And they're not perfect, they get stuck, they pinch the skin, and we all know what happens if the zipper
18:51on our pants refuses to stay up.
18:53Well, luckily, this can be avoided.
18:55Most zippers have a locking mechanism built right in.
18:58When the zip is facing down and flat against the teeth, the lock is engaged and the zipper remains closed.
19:05If only I had known that back in school.
19:08What about those metal rivets most jeans have?
19:11They're more than a design choice.
19:13They were added to protect areas that experience the most strain, such as pocket corners and the base of the
19:18fly.
19:19The rivets hold the fabric together, even when it's being stretched and pulled during work.
19:24And since we're talking about clothing, have you ever wondered about that tiny fifth pocket at the front of your
19:30jeans?
19:31Well, first of all, it isn't really a fifth pocket.
19:33Originally, jeans were made with four pockets, including that little one in front.
19:38The fifth pocket is actually the one on the back left, which was only added to jeans in 1901.
19:45The little pocket, though, was important a long time ago.
19:48Cowboys needed to keep their pocket watches safe while riding out on the range.
19:53Yeehaw!
19:53That pocket kept the watches protected, but also handy.
19:57And then, people became so used to it that jeans just look weird without one.
20:01Another strange holdout from a bygone day is that stitched V on the front of some sweatshirts.
20:08What if I told you that those exact stitches hold the whole shirt together?
20:12Well, then I would be lying, and I never do that.
20:16But, back in the 1940s, this V was very useful.
20:20First, the V-stitch was initially used to add a patch of stretchy rib fabric to the shirt so that
20:26it could fit over our big heads more easily.
20:28Secondly, these shirts were specifically designed for sports.
20:32So, the V included an additional piece of fabric to absorb the sweat that would build up during a game
20:38or a workout.
20:39As stretchy fabric became readily available and better at handling perspiration, the V lost its traditional value.
20:46But, like the tiny jean pocket, it has continued as a decorative feature.
20:51A reminder of our big-headed ancestors who apparently only sweated just below the chin.
20:56But, moving on.
20:58One place you won't find many people sweating is the golf course.
21:02You will see quite a few fashion disasters, sure.
21:05But sweat?
21:06Not so much.
21:08Golf was invented around the 16th century in Scotland.
21:11Back then, the ball was perfectly round and smooth.
21:14Over time, the ball would become dented from use.
21:17And, at some point, golfers discovered that these imperfections actually helped the ball fly farther.
21:23Dimples were added on purpose in the 1900s, when it was found out that they reduced the aerodynamic drag that
21:30slowed down a smoother ball.
21:31And the dimples made the balls easier to control.
21:35And, no, not all golf balls are created equal.
21:38The number of dimples can range from 300 to 500, with one company producing a ball with over a thousand
21:45little dents.
21:46Wow, a little overboard, eh?
21:48Need a quick, refreshing drink after a round of golf?
21:51Juice boxes, created back in 1963, are very convenient.
21:55But why do they have these large triangular flaps on top?
21:59Their lifted flaps act as hand grips.
22:02This stops you from accidentally squeezing a full box and spilling juice all over the place.
22:07Like onto your favorite t-shirt or the new couch.
22:11Now, when you're done golfing, grab your backpack with that leather diamond patch with two vertical openings.
22:17It's commonly referred to as a lash tab.
22:20But I much prefer its other name, pig snout.
22:23I mean, it certainly looks like one.
22:25You typically find these pig snouts on pads used by hikers and climbers.
22:29The diamond is a place to tie any extra gear that they need to carry, like boots, cooking equipment, or
22:35sleeping bags.
22:36But these lash tabs are also becoming more common on smaller backpacks.
22:40They're a nod to the past, but just as useful.
22:43Attach your running shoes to one next time you head to the gym, keeping those stinky things away from the
22:48rest of your clothes.
22:49Now, I'm sure you're a great driver.
22:52But for years, you've probably been neglecting an important safety feature right in front of your eyes.
22:58That rear-view mirror has a small tab located at the bottom center.
23:02It's high time you started using it.
23:04When this is flipped forward, the mirror is in day mode, providing a strong reflection of everything behind the car.
23:11Flipping the tab backward changes the whole situation to night mode.
23:15This reduces the brightness of the headlights behind you, resulting in a safer drive.
23:21Another cool car tip?
23:23If you're borrowing from a friend, using a rental, or have the memory of a houseplant,
23:28cars feature a handy indicator to let you know which side the gas tank is on.
23:32It's a tiny arrow next to the pump icon that points either left or right.
23:37Where the arrow points, that's where the gas tank can be found.
23:40And that's one less thing you have to remember.
23:44Okay, off to the grocery store.
23:46A regular shopping cart has a useful feature you might have been overlooking.
23:50Carts usually include loops in the metal frame, often behind the child seat.
23:55As you bag your groceries, hang the ones with fragile or squishable items, like eggs or bread, on these loops.
24:02Now, they're out of harm's way when you toss that giant watermelon into the cart.
24:08Later, when you're unloading your groceries, do yourself a favor and grab that box of plastic wrap.
24:14You know, the one that is impossible to unroll without the whole tube coming out while the plastic wrap sticks
24:20to itself.
24:21Check out either end of the box, and you'll see small tabs that you are supposed to push in.
24:26This helps to hold the roll in place, so you can easily pull the plastic wrap out without all the
24:32fuss.
24:33Aluminum foil boxes also have these tabs.
24:36Now that you can finally use that plastic wrap, try this appealing hack.
24:41Separate that bunch of bananas and cover each stem in some plastic wrap.
24:46The stem releases a gas called ethylene.
24:48When it reaches the rest of the banana, it encourages the fruit to ripen and turn blank.
24:54If you wrap the stems, your bananas will last longer.

25:07Of course, as you open the microwave, you'll notice that the glass in the door has a strange black mesh
25:13inside.
25:14This mesh is designed to stop any radiation from passing through the glass.

25:28Thank you, science!
25:29Oh, and about that cup of coffee.
25:32Did you know that the handle size can help you determine how much the mug actually holds?
25:37Let your fingers guide you.
25:38If you can fit two fingers into the handle, then the mug holds 8 ounces or one measuring cup of
25:44liquid.
25:45Three fingers, 10 ounces or one and a quarter cups.
25:48Four fingers, 12 ounces or one and a half cups.
25:51Pretty cool, huh?
