You give the four Kings to a spectator. You cut the deck saying that you'll now cut to one of the Queens. The spectator's task is to try to pick the King that will be the perfect mate for the Queen you cut to. Remove the top card of the deck and the spectator picks ANY King. The two cards prove to be the King and Queen of Clubs! This is successfully repeated with the remaining Kings and Queens. Then a big surprise occurs: On the back of the four Queens four hearts appear!
Requires four double-backed cards and heart stickers.
