A brilliant synthesis of sorcery and science, Newton's Nightmare must be seen to be believed! From the mind of William J. Schmeelk comes this gravity-defying miracle. A brass weight is dropped through an aluminum tube. It rockets through, falling into the spectator's hand. So far, so good. But, at the magician's command, the weight drops through the tube in slow motion--like an astronaut bounding across the moon! The weight can be clearly seen floating through the tube! This is a great one to show the wise guys…at one-tenth the price of the original stage version!
