Featuring the return of Anthony Kelly - real-life ninja and Australia's greatest ever record breaker - this time catching tennis balls at 100kmp, while blindfolded. Professional breakdancer B-Girl Roxy is head spinning. Germany's Ronnie C Rock is car spinning. And our Officially Competitive contenders take on the world's longest backwards jump.

Kayaker Claire O'Hara returns with an incredible record attempt, balloon-modelling expert Ryan Tracey makes balloon elephants without even looking and a man from China shows off his remarkable chin. Meanwhile, Officially Competitive showcases one of its toughest events yet - flipping and catching drinks coasters - with chopsticks. Will Cherry, Ray or Steve triumph? And who will be dumped into the gunge tank of doom?
