Peanut Shaped Double Cylinder Low Temperature Difference Stirling Engine Model Educational Engine Model

Features:


.Interesting Structure: Unlike most low temperature Stirlings on the market, this product uses a two-cylinder linkage structure, and the two bases are simultaneously operated by a flywheel in the tropics. When operating, the connecting rod swings up and down like a balance

.Reliable Quality: aluminum alloy base (after sandblasting and black oxide process), aluminum alloy column, iron flywheel (with nickel plating process), brass power cylinder block, overall texture

.Simple Operation: Place the base on the cup with hot water. After preheating for more than ten seconds, use the flywheel to assist the engine and the engine will run by itself.

.Theory: The focus of the low temperature Stirling engine operation is the temperature difference, which is the conversion of thermal energy into mechanical kinetic energy. Use high temperature water during operation, which will result in a larger temperature difference for better engine operation. Also, don't touch the water on the base.

.Use Value: Through the hands-on operation, you can observe the entire engine running process, more intuitive understanding of the operating principle of the low temperature Stirling engine, and deepen the interest in physics learning.

.The product design is exquisite: the workmanship is excellent, not only can you get started, but also can be used as a beautiful decoration.

.Suitable for people over eight years old

Comes with pump
Color: Colorful, Size: Large
My dogs enjoyed it but it’s not large dog proof. I have a husky and German Shepard…..the ball lasted a day before it was torn up. But this would be perfect for smaller or medium sized dogs.

The answer to calloused feet.
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.
