Ed and Oucho's Excellent Inventions - Series 1 - Flying Pizzaling

Factual programme. Ed and Oucho are travelling all over the country making inventions. They are trying to build the Flying Pizzaling, a flying pizza deliverer. It starts off well, until Ed 'borrows' helium balloons from a birthday party and their cheese lifting experiment descends into a food fight. With the Big Big Cheese on their backs, will their general uselessness and lack of science know-how stop them from building the Flying Pizzaling in time?
