Any Two Books
Any Place, Any Time
Completely 100% Truly Impromptu Book Test

So many possibilities!

You are in someone’s home or if you prefer a library or bookstore. Anywhere. Someone goes and gets any two books. You never see or handle either until the participant puts one in your hands. She keeps the other, which you have NEVER seen or touched.

You flip through the pages of your book until she says “STOP” This is an absolutely free choice and the participant notes the page number. She goes to that page in her book and remembers a word. The books are exchanged and the process repeated. You are immediately able to reveal both words in any way you choose!

Additional Routines & Suggestions By:

Andrew Gerard, Dr. Bill Cushman, Greg Arce and Richard Osterlind

Also included is a special bonus routine: “Watch It!”
Again completely impromptu! Josh Zandman applies his IBT principles with two borrowed watches.

You and a participant each select a time on a watch and write it down. The watches are switched and the process repeated. Your times match. Twice. So strong and yet so easy to perform!


"Josh Zandman's IBT is a clever extension of known principles for the famous David Hoy book test. How wonderful that Hoy's original creation is still going strong after half a century! This latest arrangement would make Hoy smile. I did, and you will too." -Richard Busch

“One of the finest book tests I have seen. Truly impromptu. Any books, anywhere, any time. I have used it in my show and got an excellent response.” -Tony Razzano

"Zandman's IBT is very clever, very direct and very usable! I'm adding it to my toolbox of truly impromptu effects." -Timothy Hyde

“Josh Zandman’s Impromptu Book Test should be in every mentalist’s arsenal. If you like simple, direct and hard hitting mentalism, as I do, then IBT is definitely something you will use and enjoy performing.” -John Smetana

“This is one of those "D'oh, why didn't I think of it?" ideas! … And the point that it’s so easy to do only sweetens the satisfaction of performing it.” -Jheff
