2.Prohibit to add oil to lubricate.Because the oil will mix with dust in the air, and become a oil-dirt, finally make the friction to be even bigger.The stirling engine can't run freely.

What is the stirling engine?
A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.The engine is like a steam engine in that all of the engine's heat flows in and out through the engine wall.

How it works?

This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid,the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.

You can put the stirling motor toy in top of hot water to make the temperature difference. You also can put it in top of ICE to get the termperature difference, Just enjoy the toy!

List price: $8.99
Brand: Sunnytech

Features: 
Principle: Not only demonstrates a pendulum, but also shows the Laws of Conservation of Momentum and Energy. Newton's Principle is that "action and reaction are equal and opposite."
Include: Balance Balls Desk Toy * 1pc Stainless steel frame and 5balls, Nylon threads. Attention: Friction and damping effects are inevitable
Size:90mm*75mm*90mm/3.54in*2.95in*3.54in

History of the toy

Newton's cradle, named after Sir Isaac Newton, is a device that demonstrates three main physics principles: conservation of energy, conservation of momentum and friction via a series of swinging spheres. Most people think that Isaac Newton invented the apparatus commonly called a Newton's Cradle, but he didn't. English actor Simon Preble invented the device in 1967 and named it in honor of Newton. In 1968 the first portable version hit the market and quickly gained popularity around the world as a fun, educational physics demonstrator. 
Newton's cradle is a device that demonstrates conservation of momentum and energy using a series of swinging spheres. When one on the end is lifted and released, it strikes the stationary spheres; a force is transmitted through the stationary spheres and pushes the last one upward. The device is also known as Newton's balls or Executive Ball Clicker.


How to play: Lift one of the 5 steel balls at either end and let it swing back--the ball at the other end will swing out the same distance as the one you lifted, proving the scientific theory and mesmerizing you for hours. Or life two of the 5, it also works. Gallery picture show you details.Fair warning: it's totally addictive! Attention: It is not an item that never stops working. The balls continue in perpetual motion for ONLY 15-25 SECONDS due to the resistance of the air and friction if you know more about the law of energy conservation, you will not ask why.
