SP Sessions with Nick Trost Nick Trost has always been a prolific inventor of clever, workable magic effects. In this 42 page, spiral bound, book in very good condition, Nick Trost presents 17 effects and 6 routines of workable, audience tested mental magic and mentalism using ESP cards.If you don't use ESP cards they make wonderful patter pieces because you can talk about J.B. Rhine's experiments at Duke University which started in the 1930's. The important element is never treat a deck of ESP cards like a deck of playing cards. The ESP cards are just tools to exchange thoughts and images.All of the effects rely on subtlety so the attention can be paid to the performance and not the technique. A wonderful collection of a budding or building performer.
