I saw a Christian magician using a bill that was specially printed with Jesus Christ in place of the presidents picture. The picture was cut to form a flap or door around the inside of the bill. When holding the "flap" on the face of the note, the bill was folded by the magician and then unfolded to reveal the back and front sides of the bill had reversed while all the time the held face hadn't changed. This person has forgotten where he purchased it or where to find information on this great trick. Can anyone help to locate this product or info on making this paradoxial trick. He had said his daughter is a physicist and says this is purely impossible. He loves fooling her with it and yes it is a real fooler with a great Christian patter that goes along with it. Thanks.
