A great routine with the lie sector plot that can be performed at any time with any small packet of borrowed playing cards. Obviously this can be done with your deck of cards which can be shuffled and the spectator can remove the amount of cards needed for this effect. Shuffle them and select any one of the cards. Complete free choice on all levels which is pointed out to emphasize the fairness to this effect. Then the questioned but encouraged to lie or tell the truth because the packet of cards will reveal the truth or lie detection. This is a sure fire revelation and works every time without a glitch. Great fun. Easy to do and can basically performed right after you take the lesson. You’ll love it. Goes so well with many of the other effects available here.
