The magician introduces a drinking glass which has been sealed with a piece of rubber.
Sitting on top of the rubber is a coin (any coin may be used).
The magician now begins to rub the coin with his finger and the coin visibly YES VISIBLY begin to melt through the rubber.
Glass, rubber and coin are now left for examination. No duplicate coins, No switches, No sleight of hand - just visual magic at its best!
