A brass tube and solid steel ball are offered for examination. The ball is LARGER than the diameter of the tube, but, the magician causes the ball to sink INTO the tube and rise again. Of course, should a spectator try, he finds it impossible as the ball remains on top of the tube. A splendid pocket trick.
