One and
Only Trick by Paul Harris & Tony MaClaren
An Invisible Deck without the deck!
You remove a flat,
invitation-size envelope from your pocket and dump out an "invisible
deck". You direct a spectator to freely "destroy" these
imaginary cards until only a single card remains. Let's say the Queen of
Diamonds.
The spectator tosses the invisible Queen of Diamonds toward the envelope. You
then slowly and cleanly remove the "one & only " card in the
envelope. It's the spectator's "one &only" Queen of Diamonds.
