Don't take our word for it. Take theirs..."Practical Thinking is great for close up, platform, or stage! Packs flat, plays big...all at an affordable price!"--Jeff McBride. "A diabolically direct handling makes Practical Thinking great mentalism for "real world" performers."--Alain Nu. You display a stack of nearly two dozen plastic cards, each with its own geometric design printed within it. You also display a laminated sheet and a marker. The designs are mixed and then each one of four spectators is asked to select one of the symbols, the selection is free...no force of any kind is used. The spectator is asked to concentrate on their symbol as you begin drawing on the sheet...the image comes into focus and you are able to draw a perfect replica of the selected symbol! The effect is repeated with all of the selected symbols and each time you match the chosen symbol with complete and unfailing accuracy! All may be examined and the effect can be instantly repeated! Comes with everything you need...the geometric plaques, marker, laminated drawing sheet, and full instructions. The drawing sheet is re-usable and youll never have to replace it! The effect can be performed close-up or it can play easily in a platform show. There are no sleights necessary and youll be able to accomplish the effect within minutes of opening the box!
