Remember when we were all about the floss? Well, these days it's all about the triangle dance!
You need three people for this latest dance craze. Stand in a triangle with your hands on each other's shoulders - and take it in turns to jump into the middle.
Watch out though - you need to make sure you jump at the right time or there'll be a few bruised knees!
Some of you are already doing it in the playground - so the Newsround team decided to have go.
Check it out!
