INTRODUCTION: This mentalism effect is super easy to carry (in your wallet). All you need is a dollar bill. It is available at a moment’s notice. It is quick and very baffling. The method is clean. It will make your spectator think that you can truly read his mind.

EFFECT: The mentalist removes a dollar bill from his wallet. He shows the bill’s serial numbers. Explaining that all U.S. paper currency has an 8-digit serial number, the mentalist asks the spectator to observe the serial number and to only select in her mind any ONE of the 8 digits. It is a completely free choice, no force! Even with an option to change her mind, she calls out the 1 number she is thinking of. When she does, the mentalist immediately turns around the bill to show that he made a permanent prediction in bold sharpie ink that matches her selection. Simply amazing!
