VIDEO: Mindflex – the Screwball Scramble game you control with your mind..

This game lets you make a ball levitate with your mind. Yes we just said that. It measures electricity in your brain and the more you concentrate, the more the little ball flies.

Real magic this one. Gerald gives his brain a work-out and explains how it works..
