Three spectators are invited on stage. Three markers, red, green and blue are handed out to the assistants, who have a free choice of any color. Each helper also receives a piece of paper.
Each spectator is asked to form a picture in his head about something the magician could not possibly know. Once they have formed the picture, they are asked to capture it on their sheet of paper by drawing it. The magician takes the very same markers the spectators were using and on a tablet of paper, duplicates all three designs - in the same colors they have been drawn by the spectators. The magician's drawings and the spectators match perfectly!
