Three marbles move but never touch... Why?


Three glass marbles in a liquid filled tube. What's so special about that? Well, no matter which way you turn or tilt the tube, the three marbles will move together but they never touch... This is a great brain teaser, but what's the trick? Is it magnetism? Anti-gravity? There's more than meets the eye! Perfect for a science table or a fabulous discrepant event. Colors may vary.
