An invisible deck of cards is shown. The spectators will exclaim that there is no deck of cards to be seen and that you are crazy. You tell them to play along with you and pick a card from the invisible deck. After the spectator has chosen his “invisible” card, a real or visible deck is produced.
You tell the spectators that this deck has one card turned upside down and that by coincidence, it is the same card as the one selected from the invisible deck. Of course you are 100% correct.
