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.

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!
