Five cards with black suits are repeatedly and openly mixed with five cards with red suits. Each time, though the mixing is more and more fair, with nothing more than a shake of the packet the colors separate-all of the black suits together and all the red together! Absolutely no sleight-of-hand is required to perform this visually stunning routine. Comes complete with the necessary, specially-printed Bicycle cards and detailed, fully-illustrated 16-page instruction booklet.
