Another magic trick. This is a replica of a trick built over 100 years ago. A billiard ball box is like a sliding die box except for the fact that dice are not used in the trick. A solid billiard ball is placed in one side of the cabinet. The magician claims it has vanished but the audience clearly hear it rolling to the other compartment. Back and forth it goes with the magician slipping up now and again until eventually all the doors are opened to prove it really has gone.
