魔术师拿出一蓝一红的十字形盒牌，从红色的牌盒中取出牌，向观众展示一下。让其任意挑选出一张，并且在牌上做好标记。然后，魔术师将牌放回牌盒中，打开蓝色的扑克，把牌取出。

在蓝色牌中只有一张红色的牌，正是观众所选的，并且做记号的那张牌！

Crossed Cards

Prove that two objects can occupy the same space at the same time!

Effect: The magician removes two packs of cards which have somehow been pushed together. He removes the red-backed deck and a spectator freely chooses a card. Their selection is replaced in the pack and all of the cards are placed back into the red box. The performer then opens the blue box and removes a blue-backed deck of cards! He spreads through the deck and finds one red-backed card-the spectator's selection!

Comes complete with specially-made boxes and photo-illustrated instructions.
