Any Tome, Anywhere by Dave Forrest

Any book can be used - you DO NOT need to know ANYTHING about the book ahead of time. Your spectator generates a random page number on their own phone's calculator. They turn to that random page in the book and read the first few words. You immediately read their mind and tell them precisely what words they have in mind!

This is genuinely impromptu, easy-to-do mentalism, any time, anywhere with any book!
