This week it's the finals of Newsround's inventions competition, You Too Can Be An Absolute Genius.

All week on Newsround the finalists are showcasing their inventions to a panel of clever judges and on Friday you'll find out who's won.

The first group of finalists have already demonstrated their invention, the magno-stick.

And our second group pitched their idea of the super useful bunk bed box.

Now it's the turn of team three, who have come up with a great idea to help with tricky swim hats.
