Take care. Working with these objects and effects is inherently dangerous; anyone who attempts them does so at their own risk. Anybody under 18 is advised to undertake them only with a parent's permission and supervision.

Performer shows a card, an envelope, and a pencil. He gives card and pencil to a spectator with request to write any number between one and a million. Card is then sealed into envelope. Spectator is asked to concentrate on his number. Performer takes pencil and in a moment writes spectator's number, digit by digit, on the envelope. Card is then removed from envelope and the two numbers shown to check.
