Christmas Carol Book Test by Josh Zandman
Christmas Carol gives you the freedom to perform a powerful mind reading miracle, anywhere at any time, without the need to memorize a single thing. You can also hand out the book before, after, or during the performance without worries of revealing the secret. The method is so cleverly disguised and practically undetectable, even under close examination.
For over 10 years, many of the world's most talented magicians and mentalists have included Josh's book tests in their paying shows and performances.
