Stirling Engine Hot Coffee Tea Steam Boiling Toy Kit

Low Temperature Stirling Engine – Desktop Heat-Powered Motor | Educational Toy and Gift

This elegantly designed low temperature Stirling engine is a beautifully engineered model that demonstrates real thermodynamic principles in action. Built with precision and care, it makes an ideal desk toy, educational tool, or unique gift for anyone with a curiosity for science and mechanics.

Crafted with Quality Materials
Each component is made for durability and smooth operation. The base is crafted from mirror-finish stainless steel, paired with a glass cylinder liner, bearing steel shafts, zinc alloy flywheel, and precision bearings. All parts are treated to resist rust and require no lubrication—oil-free and easy to maintain.

Simple and Engaging Operation
Place the engine on top of a hot cup of coffee, tea, or warm water. Within seconds, the temperature difference powers the motor. Once the flywheel is gently spun, it begins turning on its own, running smoothly and silently. It even works with ice—place the engine on a warm surface and add an ice cube to the top plate to enhance the temperature difference for faster motion.

Runs for Hours
This engine is designed to run continuously for over 24 hours as long as a consistent heat source is available. Many users place it on a USB-powered warming plate (not included), allowing the engine to operate on their desk for days without interruption. Avoid direct flame or stovetops, as plastic parts may become damaged under high heat.

Great for Education and Gift Giving
Packaged in a clean, attractive gift box, this engine is ideal for classroom demonstrations, science fairs, and hands-on physics education. It’s a thoughtful gift for teachers, students, engineers, and anyone interested in mechanical motion or thermodynamics. Suitable for all ages with supervision.

Unique Conversation Starter
Whether placed on a coffee cup during a meeting or displayed in an office, this engine catches attention. Guests are always intrigued by the unexpected motion, making it an effective and elegant icebreaker.
