A rare and discontinued trick, Card in Crystal Ball by Mike Rogers. A spectator looks into a mini crystal ball and sees that it is completely clear. They choose a card, and the image of their card suddenly appears floating in the crystal ball - then just as quickly disappears again!

Ask a spectator to touch any face down card in a shuffled deck. Place the card in your pocket without showing its value. No one knows the identity of the card, not even the spectator who touched it. Bring out a small drawstring pouch. Open the pouch and remove a small crystal ball. Hold the ball between your finger and thumb, and ask the spectator to gaze deep into the ball. Tell the spectator to name aloud whatever thought she receives from the crystal. Magically, the Ace of Diamonds appears within the ball. Remove the spectator's card from your pocket and show that it is in fact the Ace of Diamonds.
