This is great entertainment for all ages. The magician takes the audience backstage on a magic trick in an apparent demonstration of how the trick works. A large playing card is dropped between two wooden plaques supported on a wooden tray. The plaques are removed and the card is nowhere to be seen, until the audience is shown the card hanging from beneath the tray. This is repeated under the pretense of explaining the mis-direction involved in magic. However, just when the audience think they fully understand, the plaques, tray and everything is shown and the card really does vanish.
A great sucker effect that's very visual and fun.
