The magician walks onstage carrying an ordinary briefcase that he puts down on a bar stool or a table. When he opens it up he removes a real bowling ball or basket ball or other large item that cannot possibly fit in the briefcase. After the production the Bowling Ball Briefcase case can be shown on both sides. The Bowling Ball Briefcase is one of the funniest Comedy props in Magic! Can also successfully be used by a clown or M.C. Remember with this improved version of the Bowling Ball Briefcase you can show both the inside and outside of the briefcase at the end of the effect. Bowling Ball not include. Go to your local Bowling Alley & buy a used cheap light weight bowling ball.
