The performer displays both sides of 2 plastic chips, 1 red and 1 black.
He asks a spectator to select one of the colors.
Both chips are now positioned on the back of the left hand which is now made into a fist.
The performer slaps down his empty hand on top of the chips. When he removes his empty hand, only one chip remains. The chosen one has apparently melted and penetrated through his clenched fist. The chip which remains on top of his fist is removed and slowly shown on both sides. He then opens his fist to show the chosen chip has penetrated through.
Complete with all required apparatus and instructions. A novel close up effect, at a very affordable price.
