Magic Tricks

This is quick, interactive, and a great entry into other, more elaborate mentalism and/or card effects (I use this as a telepathy "test" and move on to NFW/No Joke as a test of telekinesis, or at least one of using mind to change real things into things hoped for). Most important, it's mind-blowing. Act blown away yourself when the spectator "chooses" the only different-colored back, and the moment of revelation will be even more enchanting. P.S. O.P. does a speedy but highly effective teaching job.
