A pure, impromptu miracle from the mind of Joel Paschall. A card is selected from the deck, signed, and returned. An indifferent card is shown; the corner is ripped off and placed face up on the table. The rest of the card is set aside, in view.
With a slow, calculated, delicate wave of your hand over the torn corner, it visually changes into that of the spectator's chosen selection. Impossible? The rest of the card - which has been in view the entire time - is turned over as well.
the corners match. the signature remains.
