Ed and Oucho's Excellent Inventions - Series 1 - Aqua Drifters

Factual programme. Ed and Oucho are travelling all over the country making inventions from bits of old rubbish they find in the back of their van. In this episode, they are trying to build Aqua Drifters, shoes that walk on water. It starts off well, until Oucho's ping pong shoes sink without trace. With the Big Big Cheese on their backs, will their general uselessness and lack of science know-how stop them from building the Aqua Drifters in time?
