Effect: A paper bill or a coin is borrowed from any spectator. This paper bill can be signed by the spectator or a mark placed upon this coin. In the case of a bill you place it into an envelope. Give the spectator a lighter to hold in his hands and thus burn the envelope containing the bill. With your magic powers only the envelope will be destroyed and not their borrowed money. In the case of the coin, also give the spectator the lighter and state firmly that the flame of the lighter is so adjusted so that it will completely consume the coin but not the envelope. Ask the spectator for the return of the lighter, open up the lighter and found inside is their signed note or coin. They remove the bill or coin.
