Richard Hammond's Blast Lab - Series 2 - Episode 5

Science game show. Two teams of contestants compete to win a wheelbarrow-load of prizes. They need to use all their powers of reason and logic as they answer questions, perform scientific experiments, predict the outcome of jaw-dropping stunts and battle to win prizes in a furiously messy final game. While the winners go away laden with goodies, the losers have to blow theirs up. The theme is air pressure. In Mini Miss's lesson, the teams are each building a rocket launcher from a plastic bottle, a snorkel and a piece of paper. The Lab Rats take part in a game of rugby but, after realising that they have taken on more than they can handle, they try and improvise by building an air cannon in an attempt to score a conversion.
