Royal Oil by Dan Harlan

Mix the cards and with a shake of the hand the red and black suits are separated! 

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.
