'Kids Invent Stuff' are looking for ideas that use the energy from someone cycling to power crazy contraptions - the weirder the better - which links to the recent Tour de Yorkshire.
The lucky inventors will get their idea built by the Kids Invent Stuff team and tested at the Science Festival in July!
The challenge is open to all children aged 5-11 and inventions ideas can be submitted as videos or drawings uploaded to their website (www.kidsinventstuff.com).
The video introducing this challenge will be available on the Kids Invent Stuff YouTube channel (www.youtube.com/KidsInventStuff) on June 10th.
You can complete the
following form and email your invention via the website
