Bammo Lost Mentalism Principle by Bob Farmer

Bob Farmer’s Bammo Lost Mentalism Principle resurrects and refines one of the most powerful and overlooked ideas in mentalism. Building on the historic 5/3 Principle, this 153-page book teaches you how to perform self-working miracles that leave no trace of method.

Throughout history, the "lost principle" has allowed three people to choose objects while the magician's back is turned away. Then, without without complicated processes or sleight of hand. the magician reveals who holds which object. The older methods are obsolete. Here, as always, Bob takes this in all sorts of interesting and unexpected directions involving many more choices and combinations.

Our favorite effect amongst this large collection is "Psychic Blackjack" in which three participants secretly choose and hold blackjack hands while the magician’s back is turned. Without asking a single question (or even looking), the magician impossibly reveals the exact Blackjack totals each spectator holds. As a jaw-dropping finale, he names every single card in their hands. All this happens without mathematics, memory, or sleight of hand.

But that's just the start. You’ll discover:

Ready-to-perform routines – From "Psychic Blackjack" and "Psychic Tarot" to "Psychic Shakespeare," ESP demonstrations, and even a mind-bending Reservoir Dogs-themed routine. Each comes complete with methods, patter, and performance notes. In total, there are over a dozen effects.

No math, no sleight of hand, no stooges – Every effect is designed to be direct, deceptive, and practically self-working, freeing you to focus on presentation.

The History & evolution of the Lost Principle – Trace its journey from 19th-century roots through classics like Jack Miller's "The Boxes of Chang" and "Pay Day", to Eddie Joseph’s refinements, and more recently Robin Dawes’ revolutionary streamlined method.

A Treasure Trove of Effects – Over a dozen full routines, including Miracle 91, A Clue to a Lie, Celestial Lights Aura, and The Gambler’s Third Eye.
