The Hidden Features Of Everyday Things

There are quite a lot of things we come across in our everyday life, we may know the function of these things without being told. But however, some of those things have some specific features whose function is totally hidden from our understanding.

The Tiny Holes In Plane Windows

Some of us may have noticed some tiny holes on the windows of planes, but what does this actually mean? it is a general believe that air is not suppose to get into the plane from the outer environment because this could be catastrophic. However, this is true. But it would lead to a greater catastrophe if these tiny holes where not present on plane windows.

The tiny holes in the windows of planes help in keeping the windows from fogging up like cars during winter, since the temperature outside is almost always lower than cabin temperature.

More importantly, they help minimize the pressure on the outermost windowpane by distributing it evenly among the inner layers, as the difference in pressure inside and outside the plane is quite massive and without those holes, we’d likely see a lot more plane crashes due to cracked windows.

The Tiny Buttons On Jeans

Denim jeans have remain unchanged after their invention in the 19th century, they have been in vogue ever since then as an everyday attire which can be wore to several occasions and in any type of weather. If you take a close look on your jean you would notice some tiny buttons around the pockets which seem not to be doing anything significant but just fashion as we may have thought. But actually these buttons are there for some specific reason that most of us don't know about. 

These tiny buttons where made to hold the jeans all together to make it durable so that it would not fall apart since jean can be wore by people who do heavy duty works and professionals who carry heavy loads in their pocket like loggers and miners. 

Gas Pumps

Have you ever wondered what would happen if someone buying fuel from a gas station carelessly or mistakenly drove off while the nozzle is not yet detached from the vehicle tank? we think it will be pretty much catastrophic right? that petrol would be spilled everywhere, but however the manufacturers had actually thought of these incident even before they invented something like that.

Every gas pump nozzle has a breakaway device at its other end. If pulled on with force, the hose will come off, and the gas will be kept from leaking everywhere. This is quite a frequent occurrence among most inpatient drivers and fuel pump attendants. May be you may have come across one incident like that or you may have been a victim of one before.
