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.
