Ed and Oucho's Excellent Inventions - Series 2 - Hydro-Bike

Children's science series in which Ed and his cactus companion Oucho travel all over the country making inventions from bits of old rubbish that they find in the back of their van. The duo are in Newcastle, trying to build Aidan's 'Hydro-Bike', a bike that goes on land and water. But Oucho has been spending too much on cakes and bananas and Ed needs to find a job to pay off their debts. Will they manage to find out enough science to make the Hydro-Bike and will Ed be able to land himself a job?
