The magician takes two small decks of cards from a card holder, one with a red back and one with a blue back. He places them on the table and states that each consists of 4 kings and that two have been turned face up as a prediction. He then asks two spectators to choose a black king and a red king. Once chosen, he spreads the cards from both piles on the table, and the only two that are face up are the chosen kings!
He continues by turning these two kings face down, and as a second surprise, they will have a different colored back from the other cards they are with!
Finally, as a third surprise, he turns the other cards face up, and they are all blank!
