When it comes to things we own, there are many hidden features that we do not up to now despite our constant use, know the purpose they serve unless we are the designers.
The Punt under Wine Bottles
This dimple is known as Punt, located under the wine bottles. It is actually there to help the wine sparkle while in storage. Its absence means that the bottle will exert pressure from the wine and explode.
The blue side of an eraser
Back in high school, I remember certain types of erasers that had both blue and red side. Back in school, we were told the blue is meant for erasing pen writings, most of us tried it and it obviously didn’t work, we ended up tearing our books.
This is because the blue side is not meant for that, it is actually meant for erasing pencil writings on hard surfaces while the red side was meant for erasing pencil writings on soft surfaces.
The bump at the end of a Laptop cable
This bump is known as ferrite beads. The reason behind its inclusion is to prevent interference in the cable.
Hole in the airplane window.
I know this may not apply to many but actually if you happened to travel by plane and sat next to a window you noticed a tiny hole in the window.
That hole is meant to allow air to flow into the plane and also to regulate the pressure in the plane.
The little hole under the padlock
At the bottom of your padlock, there is a little hole close to a keyhole. Some have been misusing it, by using it to bend small wires when they lose their keys. The hole is meant for you to grease your padlock in case it gets rusty and gets stuck and you need to get oil in it.
It is also meant to drain water that gets trapped in the padlock. If your padlock does not have the hole, then it is made out of stainless steel and it is supposed to be used indoors to prevent water from getting in.
The little hole in pen caps
Some people may think that if this was not put by crazy person then it was beautification sort of but that is not the case.
Less the hole, whenever you close your pen, the air trapped in the cap and the inserting of the pen will create pressure which will push the ink out of the tip of the pen preventing it from writing.
Secondly, it is meant to prevent death if you accidentally swallow the cap. In case you swallow a pen cap, the hole will help you breathe easily till it is surgically removed, without it, many people would have choked on it and died.
An extra piece of fabric
When you happen to purchase a new cloth from boutiques, though not many boutiques are doing it nowadays but should be happening, you might notice there is a piece of fabric with a button on it tucked in the pocket of either a shirt or trousers.
The piece of cloth is actually meant for you to use to test how it will react with detergents when using your washing machine.
So what you need to do with is by washing it to see how it will fade before washing the main attire to prevent colors from sipping into other fabrics.
