As we go through our day to day lives, there are many things we may do almost automatically. It can range from pulling up to the pump to fill up our car with gas all the way down to leaving a sticky not for a family member. In any case, they are things we just take for granted, and if we were to stop and think about them as we did them, it would see rather mundane. The fact of the matter is, however, that there are many thing we do just find, but that doesn’t mean we are doing them correctly. This brilliant list of ordinary items will illustrate that fact perfectly.
Why there is an arrow on your car’s fuel gauge
Normally, cars have a little gas pump on their fuel gauge, plus the information on how much gas you have, but they also have a small arrow on one side or the other of that small gas pump. That arrow indicates which side of the car the fuel door is so you can pull up to the pump correctly, even in a rental car.
What rivets on jeans pockets are for
Of course, those rivets add style and a bit of flash to the outfit, but they have a practical use too. Originally, jeans were work clothes, made for carpenters, gold miners and other types of workers. When they put something in their pocket, like a gold nugget or a handful of nails, the pocket failed and ripped away from the jean. The rivets reinforce the pockets, so it doesn’t happen.
Why staplers have this part
You may have wondered about the base of the stapler and why it has two different types of indentations. One of those makes regular staples, folding them down toward the inside for a compact hold. When you push up on the anvil, it can swivel and then allow you to staple with the ends folded outward for temporary stapling or on fabric.
Why you may need a hole and serration at the end of a tape measure
Some tape measures have serrated edges and a hole in the metal end. Others may just have a hole. There are reasons for both. The serration can etch a mark if you don’t have or want to use a pencil and the hole can hook to a nail to eliminate the need for a second person holding it.
Why there is a hole at the bottom of a lock
Have you ever looked closely at a padlock and noticed one side has the place for the key and the other side has a hole. Locks are used outside and subject to the weather. Not only can you oil a lock through that hole, but also it is a drain for water after a drop of rain, so it doesn’t get rusty.
How to find out if your phone is wet inside
If you worry your phone is wet, check the battery. You’ll often see a small square or circle. It’s normally a light color, but when it gets wet, it changes to a red color. The indicator is on the SIM card on later phones like Apple Smartphones or the iPhone 5. Try using a highlighted magnifying glass or turn your iPhone around beneath a light until you see the indicator clearly.
Why there are small bumps on the F and J keys
Two letters, F and J, have a small raised bar. I’ll give you a minute while you check your keyboard. Those bars are physical guides for the touch method. You place your index fingers on them.
How to correctly tear sticky notes from their block
Believe it or not, you might be ripping sticky notes off wrong. If you pull it up from the bottom, it can create a bend in the paper and cause it to roll.
Tearing the note straight across at the top keeps your sticky notes flat and like new.
Why you need this aperture in an iPhone
Your iPhone is supposed to have a hole between the flash and the camera lens. It serves a big purpose. It helps keep the sound around you down and allows your voice heard more clearly.
Why there is a pin and a hole in a garlic press
You may have noticed a pin on the inside of one handle of a garlic press and a hole on the other handle. That’s because the garlic press does double duty. It not only crushes garlic, but the pin and hole also create a cherry pitter.
Why we need indentations in wine bottle bottoms
Initially, the conic interior of a wine bottle called punts occurred because of the way bottles were made, but they also serve a purpose. If you’re serving champagne or anything that is sparkling, it helps lower the stress on the bottle at the seams and bottom by distributing the pressure evenly. For regular wine, it prevents sedimentation from going into the glasses when you pour it by accumulating it around the punt.
