Maxello Magic

The performer announces that he'd like to try an experiment, and invites a volunteer to the stage to help him. He asks her to think of a simple object. Once the picture is clear in her mind, she is asked to try to draw the object using an Etch-a-Sketch. To make it more of a challenge (and funnier), she is asked to draw it while holding it upside down. While she is doing this, the performer attempts to draw what she is thinking on a sketch pad. When she is done, the volunteer turns over her drawing to show just a random pattern of lines. She didn't do such a good job at trying to draw the object. (No one could under these conditions!) The performer shows what he drew, and the drawings match exactly! The drawing is given to the volunteer as a souvenir.Completely mechanical.

Easy to do. Instructions, routine and special gimmick enclosed, you supply the pad, marker and Etch-a-Sketch.
