In this short, fun and informative tutorial, Andy Field demonstrates the Oil and Water trick using four black cards and four red cards. Four cards are placed on one side of the table and the four red cards are placed on the opposite side of the table. He then mixes the cards, pulling one card from each side to make a new pile of cards with alternating colors. One red, one black, one red and so on and so forth with each of the eight cards. After letting the cards sit for just a few seconds he flips them over to show that the cards refuse to be mixed and are separated into four black and four red! If you don't believe it, watch with your own eyes as he even performs the trick with the cards facing up. Enjoy!
