Deep Breath by The 1914 and Mat Parrott

The Gilbreath Principle Made Practical for Mentalism

Deep Breath by The 1914 and Mat Parrott is a detailed instructional project focused on one of the most underused principles in modern mentalism: the Gilbreath Principle. The material aims to make this mathematical concept accessible and practical, removing the need for advanced algebra or complex theory.

Instead of treating the Gilbreath Principle as an abstract mathematical idea, Mat Parrott presents it visually and step by step, using clear demonstrations and simple props. The focus is on understanding how structured chaos in a shuffled sequence can still retain hidden order—allowing for powerful and seemingly impossible effects.

The project includes over 100 minutes of instruction and multiple performance-ready routines. These effects demonstrate how the principle can be applied to cards, numbers, words, and other everyday objects, making it a versatile tool for mentalists and close-up performers.

A key emphasis of Deep Breath is practicality: no gimmicks, no sleight of hand, and no mental math are required. Once understood, the principle can be adapted to a wide range of performance scenarios, from close-up settings to virtual shows.

Included Effects

OUT OF BREATH

A spectator shuffles a deck and removes a stack. The performer is able to determine the color of every card in the stack without seeing them.

POKER IN THE REAR

A shuffled deck is used by the spectator to deal winning poker hands to everyone at the table, despite no interference from the performer.

BOOKTEST

A random page number is generated using number cards, leading to a successful divination of a thought-of word from a freely chosen book.

SCRABBLED

From a mixed set of Scrabble tiles, a freely formed word is predicted in advance, culminating in a strong finale.

LOTTERY PREDICTION

Spectator-mixed numbers match a real lottery ticket that has been in full view from the beginning.
