EFFECT: You have someone select and sign a card from a blue deck. You tear the blue card in half and put one blue half in a blue box and one in a red box. You shake and dump out the card pieces. Then piece from the blue box is still blue but the card from the red box turned red now! Still with the half of the signature on both halves.
MY THOUGHTS: I like this trick a lot. It fools everyone and I give out the pieces as souviniers. Goes for about $11.95
