Mat Parrott demystifies an esoteric mathematical principle first published over 50 years ago by Norman Gilbreath; The Gilbreath Principle.

Only a handful of the world’s most accomplished mentalists understand the power of this ingenious concept and how it can be exploited to create explosive demonstrations of power.

With it, you can:

• Effortlessly predict lottery numbers chosen completely at random.
• Sense the colours and suits of playing cards you’ve never seen.
• Deal straight flushes to everyone at the poker table from a shuffled deck.
• Divine words from books your spectator is thinking of.
• Amaze anyone over Zoom by reading minds with Scrabble tiles.

The secret principle allows you to know, with 100% accuracy, information about a deck of cards (or stack of any items) mixed by a spectator. It allows you to create and perform miracles without the use of any gimmicks and without the use of any sleight of hand.

We believe so many mentalists never truly grasp the power of Gilbreath because they freeze up when they see the algebraic equations it’s traditionally taught alongside. The effects are astonishing but on paper they sound so damn complicated to achieve!

The truth is, the principle is actually really, really easy and Mat Parrott will prove it to you (without any algebra in sight!)

Deep Breath unlocks the previously unattainable, making Gilbreath accessible for EVERYONE.

Despite having its foundations in mathematics, there is NO MENTAL MATH REQUIRED whatsoever; Even a grade F math student can begin performing these impossible demonstrations within minutes!

Best of all, because this brilliant method is so under-utilised by performers, effects that apply the principle can be massive magician foolers!

Mat Parrott, author of BREATH, begins the tutorial explaining the concept visually and elegantly using poker chips of different colours. Within minutes, the entire principle will make complete sense and once grasped, there are no limits to the amount of effects you can create and perform with it.
