Father and child place a coin in a matchbox. Close the matchbox and shake it to show that the coin is still there. When the box is opened the coin has disappeared.
Secret: The box is prepared by cutting in one end of the drawer a slit just large enough to admit a coin. The opening will not be noticed. When the box is shaken sideways, the coin will rattle, but as soon as you tilt the box towards yourself, with the trick end inwards, the coin will slide out into your hand. The other hand should then take the box and lay it aside, to be opened later.
