Yctze Stirling Engine - Zinc Alloy 6.2x4.5x3.5in

1. [INTERACTIVE LEARNING] Hands-on experience with the Stirling engine to observe power generation and movement in action. 2. [PREMIUM QUALITY] Made of zinc alloy material for durability and longevity, ensuring a construction. 3. [SAFE OPERATION] Follow the operation method to pour , preheat, and watch the car move safely and securely. 4. [VARIED USE] Ideal for scientific projects, physics demonstrations, and mechanical learning to broaden knowledge and skills. 5. [EFFICIENT FUNCTION] -powered lamp heats the piston tube, allowing dry expansion to generate power and move the car smoothly. Specification: Item Type: Stirling Engine Material: Zinc Alloy Size: Approx. 15.8x11.4x9cm / 6.2x4.5x3.5in Purpose: Through manual operation, you can observe entire running process of the Stirling engine, understand the Stirling principle more intuitively, and broaden your interest in learning physics Operation Method: Place the model in a horizontal position during the operation, pour into the lamp to ensure safety, and then turn on the lamp. After preheating for 1 to 2 minutes, the lamp heats the piston tube, the dry expands to generate power, and the car will start moving.
