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.

Shoe covers are durable and available in various weights to accommodate specific protection requirements.

Demonstrate the Stirling Design External Combustion Engine with our 18×11 cm working model. The Stirling engine currently is being re-examined as a practical source of power because of its adaptability to almost any fuel. First produced in the 1800’s as a non-electric fan and an automatic hot air water pump, the engine soon became obsolete due to its lack of sufficient power when compared to the newly developed combustion engine. Any fuel can be used with our model, but denatured alcohol is suggested for clean operation.

Dilute quantities to any volume as needed.
