Richard Hammond's Blast Lab is an entertaining and anarchic studio-based science game show set in the surreal world of Richard's secret laboratory, found under the watermill of his fictitious country mansion. Two teams of three contestants compete with each other over four rounds. They must answer true or false science questions, perform scientific experiments using ordinary household objects, predict the outcomes of jaw-dropping stunts and battle to win prizes in a furiously messy final game. The losing team must then blow up their prizes in an exploding bidet. Nothing is ever quite as it seems in this exciting, surreal and action-packed show. This time, Richard Hammond looks at the weight of liquids. Richard joins one of his lab rats at his top secret test facility to discover what happens when a tonne of water is dropped on to a car from a height of 30 metres. Meanwhile, in his underground laboratory, Richard asks the two teams of young scientists to attempt to guess how much his security guard Ninja Nan and one of his lab rats weigh. But because this is Blast Lab, there's a twist... Ninja Nan and the lab rat have to sit on giant scales, while the contestants must use bottles of water to guess their weight.
