Richard Hammond's Blast Lab - Series 2 - Episode 12

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 crew look at light amplification by stimulated emission of radiation - in one word, lasers. In the lab, the teams compete in a race to navigate their laser beams through a maze using a series of angled mirrors. Meanwhile, out on Richard's secret test facility, a special Laser Lab Rat investigates colour absorption by pointing laser beams at different-coloured balloons.
