Richard Hammond's Crazy Contraptions: Season 1, Episode 4

1 - 4: Episode 4

A team of physics-obsessed students from Leeds take on three Spanish-born brothers, in a bid to build a machine that allows Richard Hammond to water the plants without getting up from watching the TV. With surprise challenges involving buoyancy and garden shears thrown in, the teams need to think extra hard to devise a winning machine - with some spectacular, and occasionally disastrous, results.
