Scrapheap Challenge - Season 3 - Eps 1: Demolition
The teams each have to build a machine capable of demolishing a set of industrial outbuildings at an old power station in Norwich. Sadly, no explosives are allowed, but they manage all the same. The Beach Boys, a group of twentysomething surfers, decide on a straightforward, human-powered battering ram, and do something no other team has ever managed — they finish building before time is up. The Chaos Crew keeps the Junkyard Wars tradition alive, with a great, big, nasty-looking machine. They build a big hydraulic claw that can rip down walls.
