1, HIGH PERFORMANCE—- The Stirling engine is produced with high quality material. The main part is made of one-piece PC resin material. The PC material has the characteristics of high strength, high temperature resistance and harmless to the human body. The body is transparent and can visually see the movement of each part, which is convenient for understanding the principle and higher safety.
2, EASY OPERATION—- The base of the machine is made of aluminum alloy. The base is 10 cm in diameter. The cup (the diameter of the cup is less than or equal to 10 cm, so that Sterling does not fall) is filled with hot water (the water temperature can’t be lower than 65 degrees, the machine base) At least 50 degrees to run), the hot water level is close to the mouth of the cup, which will make the Stirling base heat faster. Warm up the flywheel in about 1 minute and the machine can run on its own.
3, ATTENTION—- It is forbidden to bake for a short time and it can be operated. Long time, poor temperature control will make the rubber between the base and the fuselage aging. It can not be soaked in hot water. It will also cause the rubber to aging and leak. The heat source cannot be iron cobalt nickel because the magnet in the middle of the sponge piston is magnetic. The material will suck and cause the machine to not turn.
4, PRIORITY GIFT OPTION FOR MANY APPLICATIONS—-It is an amazing and fantastic product at this price. Its elegant gift package makes it spruce up and presentable. It has a wide range of application as, great gift for Kids’ science project, Physical/mechanical learning, teacher’s Demo props on the class, birthday gift for friends, families, parents, kids, etc. Many of our customers come from school, colleague, etc.
5, AMAZING CONVERSATION PIECES ON YOUR DESK—-It’s funny to see people’s looks and reactions when they squeeze a little shot for this Stirling engine. Put it on the cup which full with hot waters, give the flywheel a gently push, and get the flywheel going, and then it works like charm. All of your guests want to know what happened, ice-breaking success. What a marvelous toy!
