The magician shows an ordinary plastic pen. The pen is shown to be a solid pen. Magician then talks about people who bend spoons and keys by mental concentration. As he is talking, the performer rubs on the pen, and the pen becomes flexible, bending like rubber. The pen is rubbed one more time and becomes solid. The pen may now be handed to a spectator for total examination. Only one pen is used, nothing is added or taken away. No sleight of hand, totally examinable and can be instantly reset.
