Cool magic trick exposed.

A cool little kid shows up to Britain's Got Talent and performs a simple trick that leaves Simon and other judges mesmerized despite the simplicity. Desis explains how this is done. There are two cards on top of each other. One has an actual hole while the other is has a black dot on the other side. The kid pusposelly wore a black T-shirt for the occasion so that no one notices the difference between the dot and the actual hole.
