Few demos are as simple and surprising as this one.
- Chain appears to levitate as it falls out of cup.
- Elevate cup above floor 5 to 7 feet. Pull end of chain out of cup to begin initial descent. Chain will self-siphon.
- While the chain falls at an accelerating rate, a standing wave develops above the lip of the cup and levitates.
- See a brief youtube video here.
- See a slow-mo video here, with a conceptual explanation.
