Effect : A strip of paper has two green dots and two black dots drawn on it. A spectator tears the strip into four pieces without you looking and drops the pieces into a paper bag.
You announce the color of the dot on a piece of paper before you pull it out. You’ve determined the color simply by touching it!
Secret : When the strip of paper is torn the green pieces have two rough edges and the black pieces have only one. You simply feel the edges of the paper before announcing the color!
