Multiplying Billiard Ball Trick

The performer shows a single red ball which magically multiplies into two more. These two balls then vanish one at a time leaving just the first ball. The trick comes with Davenport instructions. It was probably made by a German manufacturer because enclosed were also instructions in three languages, the first being in German: ‘Nr. 3169. Die sich vermehrenden Billiardbälle. [The Multiplying Billiard Balls.]’
