Ed and Oucho's Excellent Inventions - Series 2 - Rainbow a Go Go

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. Ed and Oucho are in trouble when their trusted van breaks down. They decide to build Mollie's 'Rainbow a Go Go', a rainbow-making disco machine, so that they can find a pot of gold at the end of the rainbow. They take advice from a talking mirror, the internet and a strange weather girl.
