Coin Vanishing Hanky

This is a very easy way to vanish a coin. You borrow a coin from a spectator and keep it inside this hanky and ask the spectator to hold it. The spectator can fell the coin inside the hanky. You then hold one of the corners of the hanky and whish it from the spectators hand. The coin has mysteriously vanished. The hanky is made of soft silk material and measures over 14" x 14".
