Vanish for Several Coins

Effect (a): Several coins are shown lying on the performer's right hand. He dumps them into his left hand, the spectators hearing them as they fall. A moment later the left hand opens to show the coins gone.

Effect (b): Similar to the above except that the coins are thrown one at a time from the right hand into the left. The audience sees and hears each coin arrive, but when the left hand is opened it is empty.
