This is an offbeat way of revealing a selected card. A spectator selects a card from a deck of cards and puts it back into the deck. The magician then asks the spectator to look at a glass of water placed on a coaster or a dish. As the magician creates some ripples in the water the selected card appears in the glass. One more ripple and the card vanishes. The glass can be inspected. We supply the coaster or dish, you can use any transparent glass. The coaster can be easily modified to reveal a name, number, or anything else you would like to predict.
