About this item
- RUNS FROM TEMPERATURE DIFFERENCE: Place this low-temperature Stirling engine over a sufficiently hot cup and the thermal gradient can drive the propeller without conventional fuel.
- PHYSICS IN AN EVERYDAY MOMENT: The moving piston, linkage and three-blade propeller make heat-to-motion conversion easy to observe over coffee or hot water.
- COMPACT CUP-TOP FORMAT: At approximately 7.5 x 7.5 x 11 cm and 103 g, the model fits neatly on suitable flat-rimmed cups and stores easily after use.
- METAL AND GLASS DETAILS: A mirrored base, metal support and transparent cylinder create a clean technical display with smooth, quiet movement.
- USE WITH HOT-LIQUID CARE: Water near 90°C or above is recommended for adequate temperature difference; keep the cup stable, avoid spills and allow the base to cool before handling.
