Richard Hammond's Blast Lab - Series 2 - Episode 10

Science game show. Two teams of contestants compete to win a wheelbarrowload of prizes. They need to use 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 must blow theirs up. In the Lab, the two teams use the convection created by hairdryers to keep bags in the air. Then, using great skill and dexterity, they have to negotiate an obstacle course. Out on Richard's secret test facility, the Lab Rats use the same principle to try and make a giant solar balloon. Will the sun's heat be enough to help their balloon lift up, up and away?
