The purpose of the tiny little pocket is actually for watches, it’s obvious to any Cowboys or miners reading this! This pocket was designed for cowboys in the 1800s, its where you kept your pocket watch when jeans were invented.

Do you think that the holes are designed to prevent the ballpoint from drying out? You couldn’t be more wrong! The hole is designed to allow a passage of oxygen to flow if the lid was ever consumed or most commonly chewed, causing someone to choke and blocking the respiratory system. It is reported that at least 100 people die a year in the US due to choking on pen lids! This lead to BIC introducing the hole on all their pen lids in 1991, which lead to other major pen manufacturers to do the same!

3. Why are there bumps on the F and J keys on a keyboard?

In 10 finger typing, the ‘F’ and ‘J’ keys are the home keys, this is where your index fingers rest. This helps users correctly position their left and right hands without having to look at the keyboard. So without looking you should be able to feel the correct position of your index finger on the ‘F’ and the right index finger on the ‘J’ by locating the small bumps on these two keys. This means you should be able to locate the remainder of the keys on the keyboard.

Ever notice how there is a little indention on the tic tac lid? Well, it serves as a dispenser because you’re supposed to slide the tic tac out of the tub and it should perfectly sit on the lid.

5. What is the blue side of an eraser really for?

You've always heard that it could erase pen ink. Well, it can. But it only really works on very strong, thick paper.The blue side is harder and more abrasive that the softer pink side, and takes a lot more paper off when you use it, which is why you've probably erased clean through the paper any time you've tried to use it.

The blue side of an eraser actually has a purpose! The red side is to erase pencil and the blue side is to erase pen ink!

6. What is the thick bit found at the end of many cables?

The cylinder-shaped lumps are ferrite cores, and they’re just chunks of magnetic iron oxide that are there to suppress high-frequency electromagnetic interference! You know the annoying sound when a mobile phone goes too close to a speaker? This is due to an interference, so ferrite cores are there to keep that from occurring to monitors, power supplies etc.

7. Ever wondered why train tracks have big crushed stones by the side of them?

These big crushed stones, called ballast are there to keep the rails in place. The narrow tracks can be affected by many different factors, such as expansion and contraction from heat, vibration and movement from the ground and precipitation build-up.

Although the rails aren’t used all the time, the train/freight locomotives that pass over can weigh up to one million pounds.

When engineers found a problem when laying down the railway tracks, they came up with this solution, which is still being used 200 years on. First, a foundation is built to raise the railway track high enough to avoid flooding. Ballast is deposited atop this foundation.

The hot-rod steel rail tracks are then put on top the cross ties and welded together. The tracks are attached to the railroad ties via clips, which allow the tracks to expand and contract while still attached to them.

Interesting isn’t it?

8. Do you know why you get an extra piece of fabric when you buy new clothes?

You probably always thought it was there for patches, right? Wrong! The manufacturer includes that little sample of material so you can test how different laundry detergents will react to your new garment.

Like everybody, I’m sure you always thought it was there to cover patches, right? In fact, you’re wrong! The manufacturer of the clothing includes that little sample of material so you can test how different laundry detergents will react to it!

9. Have you ever noticed the little holes in the windows of aeroplanes? 

via/DailyMail

There are two reasons why there are holes:

The first reason is to compensate for air pressure. When the plane rises in altitude, there’s a huge pressure difference between the inside and outside of the plane. The hole is there in order to regulate some of that difference so that the outer window doesn’t have to do all of the work. The second reason is that it prevents the windows from fogging up!

10. Have you wondered why cooking bowls have little holes at the end of handles?

Isn’t it annoying when you stir something in the pan and then put the spoon down on the side with a load on sauce on… Well, it turns out the holes at the end of the handles are actually really useful! It’s so you can put your spoon in there whilst you’re waiting. Meaning no mess!

11. Do you know why there is a hole in the bottom of a padlock?

There are a few really important reasons why there is a little hole there! The first reason is that it allows water to drain out of the lock if you’re using it outside, this prevents it rusting whilst its raining or freeze and break in the winter! Another reason for the h0le is that it can be used to oil the lock to keep it working well and prevent it from becoming stiff!

12. How to properly use a utility blade. 

Take a close look at the blade on your box cutter or utility knife. Notice the little score lines? You can break off the end of the blade to give yourself a fresh, sharp blade whenever you want. To do so, take that back cap off, slide the blade out the back end, and use the cap to snap off the end of the blade before putting it all back together again.

13. Why champagne bottles have those indentations at the bottom?

via/VineScope

It isn’t there so the sommelier can get a better grip on the bottle whilst they’re pouring, which is what I thought! It’s actually there to compensate for the pressure during the corking process. The side and bottom of a bottle are weak spots, and the indentation helps evenly distribute the pressure inside the bottle! That is why it’s so much deeper on champagne bottles, as they are under more pressure due to carbonation.

14. What are the wings on Apple chargers for?

via/Quora

The wings flip up so you can wrap the cable around them. Start by wrapping the thicker section of the cable around the power block, then the thinner part of the cable around the wings! You can secure the whole thing with the little clamp on the very end.

15. Ever wondered what the little hole at the end of a tape measure is for?

It’s there so it can hook onto nails or screws and measure safely without the tape measure slipping. It’s very handy!

And what about the little serrated edge?

It’s quite obvious when you see it, isn’t it? Imagine trying to mark where your measurement is but not being able to due to your hands being occupied holding the tape measure. A little serrated edge comes in very handy, and more accurate as well!
