Springboard by Michael Murray - BookSpringboard is a revolutionary new system for allowing your spectator to read minds! In this cutting edge book you will be taught the inner secrets behind this technique which had previously only been shared with a select few. Imagine for a moment that you are thinking of a card. The spectator creates a card in their mind, never mentioning any color, suit or value. Their choice is real. You name the card that you were thinking of and they freak out.
