A smash hit with cards! Nine blank-faced "Un-Cards" are dealt into a row on the table, some of them face up and some face down. Now the performer hands out a prediction. He has a spectator roll an invisible "Un-Die" to freely select a number, which is used to count to a card in the row. The selected card is shown to be the only red card. The prediction is then shown to be correct; it says, "YOU WILL SELECT THE RED CARD."
Easy to do. Complete with all the necessary cards.
