Birthday Flip Flop
Magician shows a folded panel, having 4 Red spots at the top and 4 Green spots at the bottom. He closes and opens the panel. Now, the red spots are at the bottom and green spots at the top. He repeats this several times with various different results until the spots on one side change to "HAPPY" and when he shows the other side, it reads "BIRTHDAY". An excellent effect for children's Birthday Parties.
