Decode the present to predict the future

IMAGINE THIS: The magician shows three business cards with predictions written on them. These predictions are doodles, so he announces that he's going to teach three spectators how to read them. To do so, he whispers something to each of them. The spectators sign the predictions. One of the spectators names the predicted cards and they match cards that were chosen. Finally, the magician offers to explain how to read the signs. When he puts the signed business cards over a lighted candle, the doodles visually turn into the names of the three chosen cards. You can give the three business cards as a souvenir.

• The predictions are always in the spectators' hands

• In making the selections, the spectators stop dealing whenever they want
• An unbelievable visual climax
