Ed and Oucho are travelling all over the country making inventions from bits of old rubbish they find in the back of their van. They are trying to build the Falconator, an all-terrain vehicle with a juicer and custard cannon. It starts off well, until Oucho crashes it. With the Big Big Cheese on their backs, will their general uselessness and lack of science know-how stop them from building the Falconator in time?
Ed and Oucho try to make the 'The Waker Upper', a contraption that wakes you up by opening curtains, turning on music and providing biscuits. It starts off well, until Ed realises they can use gravity and drops Oucho from a great height. With the Big Big Cheese on their backs, will their general uselessness and lack of science know-how stop them from building the Waker Upper in time?
Ed and Oucho need to find out about radio waves if they want to win Carl Trouser's quiz. So they build Hemang's Davenportanator, a remote control spider that zooms around the London streets, shouting and squirting water, to help them on their mission. It starts off well, but a mix-up with frequency means Major Cake needs to send his frequency testing machine, which ends up a trifle messy! Will Ed and Oucho make the Davenportanator and win the prize they are after?
