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 the Icecoolator, an ice-cream-making bicycle. It starts off well, until Ed realises the ice cream won't freeze and the bike keeps falling over. With the Big Big Cheese on their backs, will their general uselessness and lack of scientific know-how stop them from building the Icecoolator in time?
