Posted on

We see these things every day but often don’t even notice their obvious functions or know what they’re really used for. cool stuff, cool stuff, cool stuff

We at Op-cast.com have now learned why there is an arrow on the car fuel gauge and what indentations in bottle bottoms are for — and we’re happy to share this knowledge with you.

1. Why there is an arrow on your car’s fuel gauge

Car manufacturers added this little arrow for drivers to know which side of the car their gas tank lid is without looking from outside. It’s very convenient if you’ve just bought a new car or borrowed your friend’s car. However, not all cars have this feature. cool stuff, cool stuff, cool stuff

2. What rivets on jeans pockets are for

Jeans were originally designed as durable working clothes for miners and gold prospectors. There was a problem, however, because pockets couldn’t withstand the weight of tools and nuggets and so they tore off. Therefore, the rivets were made to prevent this.

3. Why staplers have this part

In its “normal” mode, a stapler bonds papers with staples on the inside. If you turn the silvery platform 180 degrees, though, staples will bend to the outside, making it easy to take them out if needed without hurting your fingers and also saving the papers.
