A DIY lover has left people gobsmacked after revealing why extension cords have tiny holes in the back of them.
It may seem as though the small key-hole openings don't serve much of a purpose, but they can actually be used to help clear wires off the floor and make the cord easier to access.
TikTokker @stusrestohut posted the explanation in a short video entitled "How to fit an extension cable the easy way in less than 60 seconds", which has left many people surprised at the fact they've been doing it wrong all this time.
