The manufacturer is unknown for this pretty cool piece of apparatus. Different colored metal balls are hinged together and all close up into one ball, yellow one side, green the other. This set is almost like the Morgan Multiplying Candles effect, but more difficult to use.
You'll have to devise your own method to produce or vanish this set. Difficult to use with one hand, but perhaps using 2 hands and producing each ball between your fingers of both hands...Hum?
- Very Unique Vintage Set. Balls are approx. 1 5/8" diameter
