A baffling multi-phase mental magic effect using a very thin drawer with cover and three chips with ESP symbols. The three chips are placed into the drawer which is closed. One of the symbols is chosen … no force or equivoque. When the drawer is removed from the cover, the chip matching the freely chosen symbol is now missing and is shown to be the one you predicted they would select.
The mechanical drawer is cleverly designed. You can make whichever chip needed vanish while closed. Perfectly crafted as usual by Thomas.
