Profound is my evolution of the Mother of All Book Tests.

Using multiple hidden principles, the book allows you to secretly extract a merely thought-of word without the participant ever having to openly reveal the first letter. The result is a cleaner, more direct and more impossible experience for your audience.

The book has been designed to read like a genuine novel, allowing spectators to casually flick through the pages and read naturally without suspicion.

As a bonus, Profound also includes a complete reverse book test routine. After you’ve impossibly revealed their thought-of word, the roles are reversed, and the spectator reads your mind, creating the perfect ending to an already impossible demonstration.

If you’re a fan of the original Mother of All Book Tests, Profound is the natural next evolution
