The Spiral Principle is a new concept in magic that allows you to perform miracles with a borrowed deck of cards. Imagine having a spectator shuffle， freely select a card then lose it back into the deck. Without doing anything you instantly know what their card is and it’s location in the deck. Included on the DVD are 5 killer effects that would not be possible without the spiral principle including N.A.C， a hands off ACAAN with a twist that you have to see to believe. Once you learn The Spiral Principle your card magic will NEVER be the same again.
