Two more mind boggling Bob Hummer effects! First, new clearly written, illustrated instructions for Bob Hummer's Mathematical 3-Card Monte. Three cards are placed in a row and numbered one, two and three. With the performer’s back turned, the spectator is given free reign to repeatedly shift the position of any two cards. As he makes each move, he calls the numbers of the positions of the cards he is shifting. When he is done moving cards around, he is asked to select any one of cards and then, secretly shift the other two cards without telling the magician. The magician turns back around and is immediately able to divine the card the spectator is thinking of! It's an incredible effect which you can also perform with borrowed objects (instead of playing cards), or present as a mental Three Shell Game; where you find an object hidden by a spectator under a cap, cup, thimble or shell! These variations are fully explained. In addition, this manuscript also includes two versions of Bob Hummer's "no questions asked," five-card mental selection revelation; including a brand new version where you reveal the thought-of card without ever seeing the faces of the cards! 8 typeset pages.
