There are just four weeks left to enter our inventions competition - You Too Can Be an Absolute Genius!

We want you to get into a team at school and dream up inventions that solve everyday problems.

The top four teams will get to pitch their ideas to a panel of celebrity inventions experts - and the very best invention will be professionally made and showcased on Newsround!

Joe's been to visit a class that are getting involved.
