A spectator selects a card from the deck and the magician displays a small polished aluminum box. He takes off the lid and removes a small piece of clear "photographic" paper, explaining that the paper is heat sensitive.

The paper is placed back inside the box and the spectator holds the box and his chosen card between his palms. After a few moments the spectator opens his hands and may remove the lid from the box himself. Inside, he finds the paper developed with an x-ray image of both of his hands and a picture of his selected card!

Comes complete with box, clear paper and two x-ray images (different cards).
