Book Test Mentalism

An old-fashioned mentalism trick that is kept alive by modern magicians such as Derren Brown and Chris Angel.

How the Trick Works:

The mentalist produces three books and ask a participant to select one of them. Another participant cuts a deck of cards anywhere they like and adds together the values of the first two cards on the bottom pile. Whatever number they get, the mentalist tells the first participant to turn to that page in the book and concentrate on the first line of the page.

The mentalist focuses and then announces a few words. Then picks up a notepad and scribbles something onto it. They tell the participant to read the sentence aloud and it matches what the mentalist has written.

Book Tests are a staple part of mind reading and there are hundreds of methods. This is one of the simplest and utilizes another stacked deck, know as a 14/15 stack.
To create the stack, pull out the Ace of Hearts and Ace of Spades and organize the remaining cards as follows, with the 7D at the bottom, all cards face down:
7C 8C 6D 9S 5C 10H 4D JS 3C QS 2D KS AC KH 2H QC 3D JH
4S 10C 5D 9C 6S 8S 7S 8D 6H 9H 5H 10D 4C JD 3S QH 2S KD
AD KC 2C QD 3H JC 4H 10S 5S 9D 6C 8H 7H 7D

Wherever the cards are cut, the first two cards on the bottom stack will always total 14 or 15. You can use a Force to make the participant choose a certain book or you memorize pages 14 and 15 and use this method:

A variation on this trick is to read and understand what’s happening on pages 14 and 15 of the three books. You can then draw a picture that illustrates the action in the book the participant chooses.
