Hovercraft
This week's programme features a special contest to help celebrate 10 years of Scrapheap Challenge.
It's a blast from the past, taking inspiration from the very first episode, when two teams were challenged to race makeshift hovercraft around the Scrapheap course. But 10 years on the stakes are higher, as two hand-picked teams from the very best shows of the past decade go head-to-head in an attempt to build hovercraft that will carry all three of their team members across both land and water.
It'll be a battle to remember as the academic Bright Sparks go up against the muscular Grunts.
Who will win the Scrapheap birthday challenge – brains or brawn?
