Slate of Mind (Book of the Mind) by Maverick Magic, Peter Warlock

(c. 1958,2005) (Submit Review) (Submit Update)

Slate of Mind (also know as Book of the Mind) employs a clever mechanical slate used for a book test and was invented by Peter Warlock and marketed by Harry Stanley and Max Holden c. 1958. (It is not to be confused with a slate and 6 card effect of the same name invented by U.F. Grant)

This version by Maverick Magic is a modern reproduction of the Warlock effect and looks and works well. Another version of Warlock’s Slate of Mind can be found here.

It has a wood frame with a grey plastic writing surface like a slate and a Crib hidden inside that is viewed by sliding a secret pin to one side.

It comes with three paperback books with a Western theme, and the Crib is set up to give the page number and first few words of every page in all three 170-page books.  As you can imagine, the print for Cribbing over 500 words takes seven columns and is quite small.

Effect: This is the only book test you will ever want to perform. No need to peek at pages, no need for the volunteer to count down columns, and no need for phony moves. Your volunteer only needs to select any one of the three books offered, (no forcing required) look at any page they choose, name the page number out-loud, and you instantly tell them the first few words on that page. You can perform Slate of Mind with one or more volunteers, and you will always be correct Your volunteer can even he in a different room or on the telephone for that matter, no matter where your volunteer is, you are always correct with your clairvoyance. This is such an ingenious device, that you won’t believe it when you see it. No skill required, you will read peoples minds in seconds, and leave your audience awestruck!

Slate of Mind comes with three paperback books.
