EFFECT:
The spectator is shown a drawing program on the Palm. You draw a tree to demonstrate it and then erase the picture which you drew. Explain that you are going to make a prediction about an event that is going to take place in the future and that this event will involve a unique three-digit number, which may or may not have significance in the spectators' life. When the spectator is ready to begin, you write down a three-digit number on the screen of the Palm Pilot which you believe they will be thinking of. The handwritten three-digit number you predicted exactly matches the three-digit number the spectator is thinking of!
