This amazing demo starts when an end of a 50-ft length of beaded chain is pulled over the edge of its container. As the end falls and accelerates, the chain rises higher than the rim and seems suspended in the air. Students see this as a discrepant event. They will ask to see it again and again. This demo is great for explaining self-siphoning polymers and Newton's First Law. Holding the handle of the included large mug enhances the visibility.
