A spectator's watch is borrowed and placed in a small bag. The bag is placed inside the barrel of an 18-inch cannon. Spectator holds empty wooden box on top of his head. Performer promises to fire the watch from the cannon into the box. To prove that the watch does, in fact, fly, a matzoh cracker is held between the cannon and the spectator. When the cannon is fired, the matzoh breaks. The watch is discovered inside the box. Includes instructions. Brass is oxidized, else in very good condition.
