Water Crystal by Tenyo

A spectator selects a card from the deck, and remembers it.
The magician pours water into a container, and asks the spectator to concentrate on her card as she gazes at the water surface.
An image of the selected card magically appears below the water’s surface!

This gradual appearance, and slow vanish, of a spectator’s selected card looks like real magic. In addition to revealing a selected card, it is also possible with Water Crystal to reveal a message of your choice, such as “Congratulations!”
