As you explain, you proceed and hand a spectator a felt tip pen and a piece of tissue paper with the request that he will either write a number upon it if he is a business type person, or a letter if he is more of romantic. You then ask him to show the audience what he has written. When he has done this, you tell him to crumple the piece of tissue paper and place it in an ashtray. You then hand him a box of matches (or a lighter) and ask him to burn the paper until it turns to nothing but burnt ashes. You then proceed and reach into the ashes. You gather the burnt ashes and slowly sprinkle them up on the back of you hand. As you Brush off the ashes, slowly and visible, whatever the spectator wrote appears written in ashes on the back of your hand.
