Ben Shires, Al Jackson and Haruka Kuroda witness record attempts from around the world in front of a live audience. Featuring world-record attempts from an incredible contortionist, a pair of martial artists who can smash wood mid-air, and upside down, and a unicycling trick golfer! Also, there is a nail-biting domino rally competition, and we send a record breaker into the gunge tank.

Ben Shires, Al Jackson and Haruka Kuroda witness record attempts from around the world in front of a live audience. Mr Cherry's Officially Competitive title is under severe threat from a determined Sizzling Steve, if not US-Ray. Our heroes face a challenge that combines bravery and bakery. Also featuring bottle-opening helicopters, outrageous acrobatics, supersonic motorised surfboards and, of course, the dreaded gunge tank of doom.

It's the final show of the series and Olympic skeet shooter Amber Hill attempts to smash a world record, as does a 1.5 tonne digger. In the final of Officially Competitive, Mr Cherry and Sizzling Steve battle it out for the championship and a record featuring chopsticks and marshmallows. And there's a final gungeing with a difference!
