We use so many things in our everyday lives from utensils to clothes , stationery to goods and many others . And all of them come with features for one purpose or the other .
In this post , there are a few things that we used in our everyday lives , which have some clearly hidden features in them . And we bet you didn't know or even care to know them still . Take a look and get to know them .
1. The small raised lines on the F and J keys of your keyboard
They are made to help you find the home keys when you are typing away .
2. That bump at the end of your laptop charger
It is not only for looks , but it helps to prevent interference in the cable .
3. Those small white hooks on apple chargers
They are not without purpose . They are made to make the task of wrapping up the cable easy .
4. The two little rivets above the soles of your sneakers or canvas
They are meant to keep your sneakers waterproof and to let in fresh air .
5. The small hole at the top of the pen cap
It is to ensure the safety of children in case they accidentally swallow it , so that they don't choke .
6. Those bottle indents , especially on wine bottles
The scientific reason fro these is to keep the pressure even when the bottle is corked . The rule is - the higher the pressure , the deeper the indent .
7. The hole in the handle of some pots
It is not merely for hanging it after washing . one can also keep the spoon there .
8. Those metal rivets on jeans
They are placed on those areas of jeans that are prone to be pulled apart by strain or movement . They reinforce stress points of the jeans that tend to tear .
9. Those small pieces of plastic inside the bottle caps
They play the role of an extra sealant and keep the liquid and carbonation in .
10. That small holes on the bottom of padlocks
It is indeed to oil the lock and also to drain water out of it .
11. The crinkled side in bobby pin
They are meant to be at the bottom that helps in keeping the pin in place for a long time .
12. That arrow gauge on your car
It shows which side the tank is on
