Effect:

While on stage you mention that you would like to tray an experiment in mind reading.  You pull out a bag from the local book store, rip it open and remove two hardcover books.  Select a spectator.  Have him verify that he has never met you and have him select one of the two books (free choice).  Have him look through the book and tell you how many pages it has.

A second spectator is now asked to name any page number in the book (free choice).  The first spectator now turns to the selected page and concentrates on the first word on that page.

You now read the spectator's mind and write down the word his is thinking of.  Ask him to yell out the word he is thinking of, then show him the word you wrote.  They match.  It's a miracle. 

But, it is not over yet.  As an afterthought have the spectator think of the last word on that page.  You can now proceed to dramatically spell out the thought of word for a double miracle.

An easy book test to perform that is worth having.   Includes 6 pages of instructions.  Condition: very fine.
