Richard Hammond's Blast Lab - Series 2 - Episode 11

Science game show. Two teams of contestants compete to win a wheelbarrowload of prizes. They 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. The theme is air pressure, and in the Mini Science round, the two teams take up the Wee Mail challenge. They must place a postcard across a cup of water and turn it upside down, allowing air pressure alone to prevent spillage. The teams must then navigate an obstacle course. Outside on Richard's secret test facility, the Lab Rats investigate air pressure by trying to use it to crush large metal barrels.
