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.
IMPORTANT: 1.Please adopt 95% to highgrade alcohol to be the fuel to make sure the air tank can get more temperature, and drive the stirling engine. 2.The temperature of Candle’s light is not workable for this toy, please pay attention.

- What Can You Do With A Horseshoe Magnet?
DISCOVER THE FUN! See what kinds of things your magnet will pick up. Try paper clips, coins, keys, pins, pens or aluminium foil.
Which of these items is attracted to your magnet? Whatever is attracted to your horseshoe magnet probably contains iron.
What are the “N” and “S” on the ends of the magnet? They stand for ‘North Pole’ and ‘South Pole’. Every magnet has two poles, a North and a South. If you have another magnet, hold it up to each end of the horseshoe. Opposite poles attract, or pull together. Like poles repel or push apart.

The silver rings of this beguiling desktop mobile spin gracefully around a central sphere. The motion is continuous and, at first glance, impossible to fathom. The secret lies in the base; a battery-powered motor spins a powerful magnet, which in turn exerts a variable force on the pendulum weight attached to the outer ring.
