Not Possible !
A card is selected and placed unseen on the table.
As the deck is riffled - another card is noted.
The deck is ribbon spread face up , the volunteer is asked to indicate their card - but they can't !
The card they noted cannot be found - it has disappeared !
The volunteer is asked to name their card.
The tabled card is turned over and found to be that very card ! !
Lots of nerve
a deck of cards and an especially gaffed 'short' card.
You must make a gaffed 'short' card as shown in the illustration below.
The gaffed card is placed near to the bottom of the deck.
Force ( Cut Deeper Force ) the 'real' 3 Clubs upon your first volunteer. Have the selected card placed on the table - unseen. Ask the volunteer to cover the tabled card (3C) with their hand.
As the card is 'tabled', casually split the deck in two and place the top half at the bottom - thus positioning the gaffed card near the centre of the deck.
Turn to a second volunteer and asks that they call "Stop" as you riffle the end of the deck.
(The face of the deck should be towards the volunteer.)
By carefully controlling the riffle you should be able to stop at the short card (AC).
Ask the volunteer to note the card that can be seen ( 3C ).
Give the deck a quick bend to straighten out the cards. Place the whole deck on the table.
Now comes a little bye-play... Ask both volunteers to hold out one hand (not the one covering the tabled card!) Lightly grasp the fingertips of each hand (as if to form a mystical link between the two people). Ask both volunteers to relax and 'clear' their minds. Slowly move their fingertips with yours as you feign 'deep mystical thoughts'.
After a moment or two release their fingertips and ribbon spread the deck of cards face-up on the table. "Please indicate your card" you say to the second volunteer.
They scan the spread out cards but are unable to locate their card !
After sufficient time has passed to build up an air of tension, ask softly "What was your card ?"
Their aswer should be "The Three of Clubs"
Turn to the first volunteer, snap your fingers over the card - saying "Please reveal the card beneath your hand"
The card is turned over to reveal - the 3 of Clubs ! ! ! !.
Before ribbon spreading the deck, pass the deck from one hand to the other - at the same time turn the deck around - so that the short end of the gaffed card is away from the volunteers.
