Effect: The magician sticks the coin into the handkerchief, turns it over and then the coin disappears from inside the handkerchief.
Secret :You secretly wrap a rubber band around your fingers and thumb.
Then you place the handkerchief in that hand. With your other hand place the coin into the handkerchief.
Then let the rubber band slide off of your fingers and onto the handkerchief, so it surrounds the coin and it is under the handkerchief.
You then slide your hand up to the end of the handkerchief and shake it.
This makes it look like the coin has disappeared by magic.
But it is really stuck in the handkerchief, held by the rubber band.
1) Place elastic band round fingers. 2) Place coin into handkerchief. 3) Slip band around coin. 4) Spectators view, coin not visible.
