Find out why these stone stackers rock!

It must be so hard to get these stones to stay in place - with no glue or cement to make them stick.

But these stone stackers are pros! They're taking part in the European Stone Stacking Championships in Dunbar, in Scotland.

The sculptures are built on the beach so they won't last long when the tide comes in.

So check out the video quick, and decide which is your favourite sculpture.
