Low Temperature Difference Stirling Engine Car Model Gift Collection Science STEM Toy

Hot Water Powered Low Temperature Stirling Engine Model Vehicle Toy

Features:

• 【Working Principle】: Low temperature Stirling engine operate with a focus on temperature differences, converting heat into mechanical kinetic energy.
• 【How to Use】: Filled with hot water at least 70℃ into the bottom metal drawer, gently flip the flywheel and the car model will start to move. The greater the temperature difference, the more power it will have.
• 【Special Steering Wheel Design】: The engine model designed with steering wheel, when it starts to work, it can not only move forward and backward, but also make simple turns through the steering wheel, giving you an interesting and fun experience.
• 【High Quality & Safety】: The wheels, steering wheel, seat are made of full copper material; The flywheel parts are made of stainless steel; The rest parts are made of aluminum alloy, durable to use. Safe for children, no need to fire alcohol burner.
• 【Wide Application】: Transparent cylinder and piston, make it straightforward for you to observe the movement. Help student to better understand this physics theory. It is mainly used in classroom teaching and laboratory experiment. A best choice gift to students, teachers, children, friends and colleagues.
