A standard pack of ESP cards is displayed to the audience, and one of each symbol is removed: circle, star, wavy lines, square and cross. The performer sticks a small white sticker to the back of each one (the spectator can check that they really are stuck) and mixes them up. The spectator freely decides which of the five symbols to draw on each card, with no forces, equivoque or other hokey magician's ploys.

One by one the cards are flipped over (the spectator can flip the cards over himself) and each card perfectly matches what is drawn on its back! The cards may be fully examined.

Alakazam's Zenner-Tech is a very direct and commercial ESP test. No extraneous props, no 'sticky' cards and no sleights. It is perfect for a formal close-up or mentalism performance or as an encore piece when you need to perform a killer closer.

The spectator makes all the decisions and yet the outcome is guaranteed, every time! If you want to add a stunning mental effect to your repertoire, then Zenner-Tech fits the bill.
