Poker Chip Polka

Two poker chips are shown, one black, one white. The white chip is placed in the left hand and the black chip in the right hand. Magically they change places, then change back again. Just when the spectators think they have figured it out, you show that the chips have different, bright colors on all sides: yellow, blue, red and green! No black or white to be found! Examinable and easy to do. Printed box with illustrated instructions.
