Syrisora Stirling Engine Model Physics - 18 months - 3 years

Specification: Item Type: Stirling Motor Material: Zinc Alloy Dimensions: approx. 15.8 x 11.5 x 9 cm / 6.2 x 4.5 x 3.5 inches. Purpose: Through manual operation, you can observe the entire operation process of the Stirling motor, understand the Stirling principle more intuitively, and broaden your interest in learning physics Operation method: Place the model in the horizontal position during operation, pour ethanol into the ethanol lamp to ensure safety, then turn on the ethanol lamp.After preheating for 1 to 2 minutes, the lamp heats the piston tube, the dry air expands to generate energy, and the car will start to move. (Use 95% ethanol) Packing List: 1 x Stirling Motor 1 x Ethanol Lamp 1 x Ethanol Buffer 1 x Screwdriver 1 x Wrench 1 x Tweezer 3 x Bungee Cords (2 pcs installed on the product) Note: 1.Please allow 0-1 inch error due to manual measurement.Thank you for your understanding. 2. Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the actual item.Please take the real one as standard.
