Ball and Tube
by Johnson Products
This old pocket trick becomes a miracle when performed with our precision made apparatus. EFFECT: A steel ball is set on top of a small brass tube. The ball is obviously larger than the tube. Slowly the ball sinks down into the tube; then just as mysteriously it rises back to the top. Instantly both the ball and the tube are handed out for examination. Nothing is palmed or taken away. This is a guaranteed collector’s item that you will use. Easy to follow routine included.
