A video on YouTube is blowing minds everywhere as people realise they have been using sticking plasters wrong all along.
According to the experts at "5 Minute Crafts", there's a lot more to applying a plaster than just opening it up and sticking it on.
The 43-second clip has been watched more than 500,000 times and explains how just sticking the band aid on your finger will cause it to easily fall off.
On top of that, sticking the plaster that way means you'll have a weird fingertip that gets caught on all kinds of things as you go about your daily life.
If you use a pair of scissors to snip the sticky panels in half before attaching it, you'll end up with a much better dressing for your wound.
The small cuts lengthways will make sure the plaster sticks better and your finger won't look so bulky.
