First you go through the deck and pull out three red cards and three black cards. Place all three red cards under all three black cards. Hold the stack of cards face-up in the palm of your hand with your fingers wrapping around the edge. Turn your cards face down and keeping the bottom card face down pull it out from the bottom. Place it face down on the table and say "Red". Than you are going to do a move called the glide in which you slide the bottom card back a little bit with your fingers that were wrapped around the edge. You then take the next card and say "Red", which it is. you lay it on top of the the last red card but over lap it. Now you take the next card and pull it out and say "Red" but it is really black. You than place the black card overlapping the other two. You than side the glide card back into position and take it and say "Black", which it isn't, and place it down and start another pile just like the first one. You then proceed like before saying ! black and overlapping the cards.
Once you are done with that you take the first card in front of all the others from the black pile which should be black, and place it down in front of both piles and say "Black". You then alternate and take a card from the other pile saying "Red", and so on overlapping them. If you started with the black pile you can now flip over the first three cards which should all be black and than the next three which should all be red!
