Ed and Oucho's Excellent Inventions - Series 1 - Solar Jak-et

Factual programme. Ed and Oucho are travelling all over the country making inventions. They try to build the Solar Jak-et, a jacket that lights up, plays music, sprays water and has a walkie talkie. It starts off well: everything is working, just not all at the same time. Disaster! With the Big Big Cheese on their backs, will their general uselessness and lack of science know-how stop them from building the Solar Jak-et in time?
