Makes you think about how many more common tools have hidden features we never knew about, right? Like the hole in the pot handle (yup, thatâs for your spoon), or that little groove you see at the bottom of plastic bottles (pressure control!). Engineering is truly lowkey amazing.
If youâve read this far, congrats; youâre now one of the 2% of humans who know what the hole in a safety pin is for. To recap:
Itâs a crucial section of the spring mechanism.
It allows for tension and snap-back.
It is a touchstone during the manufacturing process.
It may even have some useful DIY applications if youâre crafty.
So next time you employ a safety pin â whether youâre mending a wardrobe malfunction or fastening it onto your punk jacket â thank that humble hole. Itâs doing more than you knew it could.
And who knows, you might just gamify your chance of winning a random trivia game or impressing someone with your freakishly specific knowledge. Either way, youâre in the know, officially.
