Here's the deal. You (the magician), place two jokers on to the table. Just two jokers. The other person (the spectator), then selects and signs a card. That card is openly placed back into the deck. Instantly, you slowly spread the two jokers to reveal a face down card has magically (yes, magically)-- appeared in between the two jokers.
Is it just any card? No. It's THEIR signed card.
This is CARBONÃ?.
