AI by Unknown Mentalist

AI here does not stand for Artificial Intelligence. It is the key to the method used in the routine.

It is a self-working effect based on a classic principle wherein a participant freely chooses any USA State name and the performer is able to reveal the same.

This routine uses double-blank business cards. There is a one-time preparation and a 3-second setup is required before each performance.

You can use the underlying principle not only for the USA States theme but also for myriad other themes and premises.
