Two-Way Prediction by Mark Elsdon

Effect:
From a spectator-shuffled deck, a participant grabs a random bunch of cards (no force!) He counts these and uses the number to randomly select a card from the shuffled deck. The magician opens a prediction that has been in view all along and reveals exactly both the number of freely removed cards and the selection. The reaction is always the same: “No Way!”
Previously only available to those who’ve attended Mark’s acclaimed 2008 lecture, this incredible prediction effect is now available in an E-Book format. This powerful effect has stunned audiences everywhere and is perfect for both walk-around and stand-up performances.
Includes: A video demo, the full handling details of Mark’s original version direct from his lecture explained in a 5-page instruction manual, a prediction text printout in MS Word format, plus extra impromptu and expert handlings.
