00:00 Ever wondered what that little hole at the top of your sink is for? There can be one,

00:08 two, or three of them, depending on the design. These holes may appear under the near rim facing

00:14 the mirror. They may face forward if they're between the faucet valves. The holes are there

00:19 to prevent an overflow and to allow air in the drain to circulate. If the hole wasn't there,

00:25 a basin filled with water would drain slowly because of the resistance it puts on the air

00:30 going out of the drain. Your bathtub also has this hole, but the kitchen sink doesn't. A bathtub

00:36 takes longer to fill, so you may get distracted, walk away, and forget you're filling the tub,

00:41 so it's kind of more necessary there. The kitchen sink has overflow protection in the shape of the

00:47 divider between the two standard basins, and this divisor rises lower than the rim.

00:55 The majority of hiking backpacks have a secret feature that can literally save your life. If

01:00 you have one, take a closer look at its chest strap. You'll see there's a built-in whistle on

01:06 its buckle. It's for situations where you're all alone, stuck somewhere while hiking, or you were

01:12 in a group but eventually separated from them. Uh-oh! Not all backpacks have a whistle,

01:18 but those modern ones, designed specifically for mountain biking,

01:21 hiking, snowboarding, skiing, and other similar outdoor activities, do.

01:26 Now speaking of backpacks, and I was, many brands have standard models that come with a patch sewn

01:34 into the outer part in the shape of a diamond. We call this the lash tab, or as some say,

01:40 pig snouts. Originally, the manufacturers came up with this feature so people could

01:45 carry an ice axe during mountaineering. They made it from leather because they wanted to

01:50 reduce the possibility of freezing. Of course, the average backpacker doesn't go on such adventures,

01:56 but the patch is still useful because you can hold and immediately access some items like

02:01 headphones or a bottle of water. Or tie your hiking shoes and some other essential things

02:07 so you have more room inside your backpack. So why do shopping carts have a grid system

02:15 instead of being solid? There could be a couple of reasons for that. Manufacturers use less metal,

02:20 so a cart is both lighter and cheaper. Also, the supermarket staff can see what's in your

02:26 cart more easily. It's easier to keep the cart clean this way too. Imagine if it was sealed and

02:32 somebody spilled orange juice or milk inside of it. It's easier for a cart to drain this way if

02:37 it's outside in the rain. Speaking of holes, why do you think laundry baskets often have holes?

02:44 It's for the laundry inside to breathe. If you use it for dirty laundry, it's harder to vent the

02:50 sealed basket and prevent your laundry from mildewing. Also, baskets without vents harbor

02:56 way more static electricity. Have you noticed there's a funky little loop on your ski glove?

03:04 Yep, the one on the finger. These gloves are specifically made for snowboarding,

03:08 skiing, or some other alpine uses. Because of the loops on the finger,

03:13 you can hang your gloves on the pack using a carabiner. Face their opening down,

03:18 and gloves won't fill with any debris or snow while you're hiking or participating in some

03:23 other winter activities. Like falling and rolling down the hill, like what I tend to do.

03:28 Now, even if you're not a professional alpine climber or something like that,

03:32 it can still be good for you to use so-called carabiner clasps. With them,

03:37 you can dry the gloves with the fingers upward. That way, if there's any condensation,

03:42 it won't pull in the fingers but roll out the bottom.

03:45 You know those silica gel packets that come with new bags, shoes, and many other products?

03:52 Think twice before you throw them away. You might want to keep them because they

03:57 preserve the freshness of your shoes or some other product you got them with.

04:01 These bags are like a drying agent since they drive the moisture out of their surroundings.

04:06 You can use them for other things, like, for instance, when you need to dry out

04:10 your phone or something else that got water in the wrong place.

04:13 Now, when dealing with a stapler, you can accidentally staple pages you didn't really

04:21 want to put together. It's not easy to remove them unless you use a simple trick.

04:25 Pay attention to the front part of your stapler. See that metal plate over there?

04:30 It's called the anvil. Turn your stapler upside down. This way, you can spin the wheel to the

04:36 temporary staple option so it won't be so hard to remove the pins. Yup,

04:41 the anvil is there so you can adjust the settings for the stapler.

04:45 Now, we're so used to toothpaste being multi-colored that we mostly don't even wonder

04:52 why it's so. Well, back in the 1970s, people became more aware of how important dental hygiene

04:59 is. They wanted their toothpaste to do more than simply clean their teeth. That's why Aquafresh

05:05 was the first company that came up with a toothpaste that had ingredients for mouthwash too,

05:10 which is the blue stripe. Later on, they added red, which represents ingredients

05:15 that help you take care of your gums. Aluminum foil boxes have a feature we can

05:22 truly call hidden. It's not like anyone bothers to take a close look at the side of the box,

05:27 right? There are rounded perforations you can punch through with your fingers. Just press your finger

05:33 into the resulting hole and hold it. That's how you secure the cardboard roll while pulling out

05:39 a foil. Beanie pom-poms look like a cute (or ugly if you're not a fan) ball on the top of your hat.

05:48 It may not have a specific purpose today, but it hasn't always been a fashion detail. One of the

05:54 possible explanations says that beanies are something the Vikings invented because they

05:59 were looking for a way to keep their ears warm throughout the long cold winters. After some

06:04 time, they added pom-poms at the top too. They were supposed to prevent the seams from coming

06:10 apart. I'm guessing the traditional horns were added sometime after that.

06:14 You can find a tomato pin cushion for pins and needles in many households. But check this

06:22 strawberry dangling from the top. It's kinda weird considering this fruit doesn't grow on

06:27 tomatoes. But in this context, strawberries are there for needles you're using at the moment so

06:33 you don't get lost while searching through a bunch of other needles on a cushion.

06:36 Take a look at the cap on top of your toothpaste tube or a cream. This pointed

06:44 cone you see inside the cap is helpful when you're opening a new tube because you can

06:49 use it to puncture the seal. Yup, no need to look for something sharp or use your nails.

06:54 Is there a pattern of blue and white bristles on your toothbrush? Sure,

07:01 it looks a bit more stylish like this. But this feature has an actual purpose.

07:05 Manufacturers design the blue dye to wear off. This mostly happens at the same time when you're

07:11 supposed to be getting a new toothbrush. They recommend doing it every 3-4 months.

07:16 But in case you forget, it can be a handy reminder. Many cars have black dots along

07:25 the window edges. It's a cool design, true. But car manufacturers probably wouldn't spend

07:30 so much of their money and time adding something that didn't have a practical use.

07:34 These dots are something we call frits, which are different than fritz the German guy. When

07:40 the temperature in your car reaches extreme fluctuations, the frits are there to make

07:45 sure the rim of the glass doesn't shatter. Good idea!

07:48 Gas cans have a very small second hole. It's there to prevent some sort of the

07:56 "glug" that occurs when air gets sucked into the hole as you pour the liquid out of it.

08:00 Because when something like this happens, the flow of liquid is not even,

08:05 which means more of it will end up all over the floor. The hole is also there to help

08:10 vent the gas and prevent the can from bursting in between uses. And that's a good idea too!
