The Click Pass
The Effect
Two coins are shown on a table. The magician places one coin into his left hand,
the magician picks up the second coin and drops it into his left hand, a click is
heard as this happens leading the spectator to believe both coins are in the left hand,
the magician shows his hands to reveal each hand contains one coin.
How It's Done
Pick up the first coin with your right hand and pretend to place the coin in the left hand,
but actually keep it in the Classic Palm
of your right hand. Pick up the second coin with your right hand and curl your fingertips around it.
Hold your right hand above your right as though you are going to drop the coin you just picked up
into it, but actually release the palmed coin so that it bounces off of the coin you just picked
up in your right fingers and into your left hand.
