The core principle underlying these effects is the classic binary method. But the twist here is that instead of "directly" identifying the target object (as done in the standard binary method), the participant is asked to identify only a group that contains the target object and not the target object directly. This adds a thick layer of deception over the regular binary method. So I call this Shadow Binary. And it is performed from a pocket card, which is an ideal EDC - Every Day Carry.
Print the included images on both sides of a double blank card. The size of the card is your choice based on how you want to perform this. Of course, you can make this card in different sizes for different performing situations. A suggestion is to laminate the card so that it will last the wear and tear for a long time.
To help in your presentation, the card is framed as a "word frequency test" from Oxford University. You mention in your presentation that statistical language studies have identified some letters of the alphabet as low-frequency letters and some others as high-frequency letters. And you propose to do some interesting and entertaining experiments.
There are 3 major effects and 1 minor effect that you can do using this card.
There are no sleights involved, no preshow, no stooges or instant stooges. There is no peeking, no tearing, no impression devices, no gimmicked cards and no secret writing. There are no progressive anagrams, no magnets, no threads, no arts n crafts, no apps, no electronics and no dual reality.
