The Sync Book Test is a completely impromptu routine that can be performed anytime, anywhere, using two borrowed books. It is built around a strong, consistent presentation that turns the effect into a genuine test of how in sync the mentalist and participant are. The routine centers on a coincidence between a number and a word, but it sets the stage for a compelling telepathy demonstration - framed as yet another uncanny coincidence: the mentalist is silently thinking of the exact word randomly chosen by the participant.
Here's how the effect appears to the audience:
A participant freely selects two books from a bookshelf - one for themselves and one for you. You both flip through your respective books, and at any point, the participant says "stop," prompting you to note a page number. The books are then swapped, and the process is repeated, this time resulting in the selection of a word. Astonishingly, both your numbers and words match. A third and final climax follows: a version of Hoy's classic book test, enhanced with subtle refinements to cleanly force a word from either the first lines or the entire page.
Book tests involving genuine coincidences are rare - especially those that are impromptu. The Sync Book Test makes this possible, and can even be performed without writing anything down. It's ideal for casual or spontaneous settings, appearing less as a display of mentalist prowess and more as a series of strange coincidences - just like the ones people experience in everyday life, which always seem to invite deeper meaning. That's what makes this effect so believable, powerful, and memorable.
Also included is a non-impromptu version that requires less than one minute of preparation and allows you to predict the very word that will be randomly chosen.
This second edition features a collection of coincidence-based book test routines - contributions from various authors in the field of mentalism, all built around the premise of two spectators arriving at matching words or page numbers.
