The Wizard shows six cards. They may be regular sized playing
cards, or jumbo sized for stage, or even Tarot cards; it's up to
you. The Wizard calls on the entire audience to each think of ONE
of the cards.
Now the Wizard scoops up the six cards and places them into
an envelope... a coin envelope for regular bridge sized cards, to
a larger manila envelope for jumbo cards. It doesn't matter, it's
all up to you. Tapping the four corners of the envelope, the
Wizard allows an on-looker to pull the cards out of the envelope
and display them to the audience. Hey Presto! The card each
person was thinking of has disappeared!
