Cigarette thru 50 Eurocent double-sided (1050)

Borrow a 50-eurocent coin and a cigarette. Now place the cigarette against the coin and it starts to melt right through the coin untill it is completely through…now slowly remove the cigarette and the coin is undamaged and can be handed out for examination.

This is the double-sided version which can be shown on BOTH sides before and after the performance.
