Going for a knockout with bubble jumping
17 November 2016 Last updated at 08:22 GMT
BBC Click's Spencer Kelly takes a break from testing tech in Japan to try his hand at bubble jumping.
Created by the Superhuman Sports Society, the game is played wearing stilts with a giant plastic bubble suit around you. The aim is to knock your opponent over.
Spencer describes the game as like sumo on stilts - but will he survive the first bout?
