Children's science series in which Ed and his cactus companion Oucho travel all over the country making inventions from bits of old rubbish that they find in the back of their van.
Ed and Oucho's campervan has become infested with cake-eating mice. This is a disaster and there is only one way to fix it - by making Joe's High Hydra. But will Ed and Oucho be able to learn science on an empty stomach while being chased by giant snakes? Will Deadly 60's Steve Backshall be able to help them? And will Ed's new pink slippers save the day?
