Check Out These Things’ Hidden Purpose We Had No Clue About

The hole in the cap of your ballpoint pen is there to save your life

If you look closely at a ballpoint pen, you will find a small hole in the cap. And although this hole in the cap may make no sense at all since, if you leave your ballpoint pen uncapped for an extended period of time, it may dry out, but there is a reason for it and it is surprisingly awesome.

Probably, you have never given it much thought, but this hole has one useful function: it prevents choking deaths. It turns out that you are not the only ones who enjoy chewing on pen lids; many others do as well, which can result in lids being swallowed and trapped in the windpipe, and it can be fatal. This hole increases airflow and the chance that people can still breathe.
