Here are some everyday objects who’s purpose you ignored before today

We have the habit of using everyday objects in a certain way...But it might not be the right way. Here are some objects you might not be using correctly.


Every day, we use a ton of various objects in our daily lives. We rarely ask ourselves questions about how we are supposed to use them. Usually, we simply use them instinctively. So, sometimes we don’t use everyday objects properly but without knowing it. Here are 24 things that you have probably used in the wrong way all your life and so you ignore their real purpose even to this day.

1. Have you ever noticed the small holes in plane windows?

The small holes are there for two reasons: the first is to compensate for the air pressure. When the plane goes up in the air, there is an enormous difference in the pressure inside and outside of the plane. The hole is there to regulate a part of this pressure difference in order to take a load off the exterior window. The other reason there are holes is to avoid the windows from fogging up.

2. Have you ever noticed your new clothes usually come with extra fabric?

23. And why do wine and champagne bottles have indentations at the bottom of the bottle?

These indentations are there to compensate for the pressure that the contents of the bottle undergo during the corking process. The sides and bottoms of the bottles are weak points, and the indentation distributes the pressure evenly inside the bottle. This is why champagne bottles, which are subjected to much more pressure due to carbonation, are much deeper.

24. Did you think the hole on your pen’s lid prevented the ink from drying?

Many people think that the cap of a ballpoint pen is there to prevent the ink from drying or that it is there to balance the pressure and thus prevent the ink from flowing. The real reason this hole is there is much simpler: it is there to reduce choking hazards. If a young child chewed the hood and choked, the hole would prevent the airway from closing completely.
