Pi Book Test from Vincent Hedan is an incredible display of memorization using something that nearly everyone has heard of, 'Pi' - the number 3.14 followed by an infinite number of digits. Hedan has created a performance piece so utterly baffling that the only logical conclusion spectators are left with is that you have done exactly as you say you have - memorised Pi to thousands of digits.
You show a small book in which the decimals of Pi are listed, and explain that you have memorised a large portion of it. You then proceed to perform a multi-phase routine in which the spectator opens the book at any page, tells you the page number, and you can tell them the first digits of the page.
Then you ask your spectator to tell you a sequence of 5 digits, anywhere on any page. Starting from there, you start reciting the decimals of Pi! Actually, you recite so many decimals that the spectator has to turn pages to follow you!
Finally, you ask the spectator's birthday, for example 14th of July. You then reveal the page, the line, and the position on the line where the sequence 1407 can be found in the book!
No crazy math
No dual reality
No svengali-like pages
Every birthday can be found in the book
