Speed with Guy Martin S01 E02 Hydroplaning Bike

"How to make things go really fast"

Guy attempts to set the world record for riding a motorcycle on the surface of water. With the help of a Cambridge professor and a team of marine engineers, Guy's stunt hinges on Sir Isaac Newton's Third Law of Motion: that every action has an equal and opposite reaction. If he can maintain enough speed on his bike, the 250-year-old theory says he should be able to achieve the seemingly impossible: to ride on water. The team master the engineering on the back wheel and the extra fittings on the bike to enable it to skim across the surface of a lake. Crashing is inevitable, so Guy endures a rigorous training schedule, trying to escape underwater from a submersion rig and then conducting a series of dizzying trial runs, hitting the water at 30mph head first. The final record attempt takes place at Bala Lake in Snowdonia - which is so deep a 10-storey building could be submerged in it - with Guy surrounded by an army of rescue teams and emergency divers.
