Sunnytech Low Temperature Stirling Engine Motor Steam Heat Education Model Toy Kit (LT001) 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.
— Awaglass Hand-blown Timer Magnet Hourglass / Magnetic Hourglass Product Description It is about time. Who knew that by just replacing the common sand in an hourglass with Magnet Hourglass you could defy the laws of space, time, and physics and make it appear to flow in reverse? But that’s exactly what happens with this Awaglass timer.
— Westminster Hand Boilers Product Description Hands Down, an Edmund Classic! — Hand Boilers are looped and twisted glass sculptures containing a liquid that will “boil” as heat is transferred from your bare hand. Simply hold the large bulb end in the palm of your hand and within minutes, your body heat will cause the liquid to rise. – Once out of your hands, it takes a few minutes for the liquid to cool down and return to the large bulb. Pretty fascinating science toy and an excellent demonstration of energy transfer. Comes in three different colors: blue, green and red – let us pick one for you.
— Westminster Magnetic Sand Timer Product Description Size: One Size | Color: BLack This desktop toy is a classic glass sand timer with a magnetic twist by using iron filaments and a base with a magnet for a mesmerizing effect.

— Radiometer by Educational Innovations Product Description Originally, designed by William Crooke in the 1860’s, the radiometer still fascinates both young and old. Whenever light shines on the four diamond shaped vanes the paddle wheel spins at up to 3,000 rpm. Great for illustrating the conversion of light energy into mechanical energy. Each vane is black on one side and white on the other. Because the black surface absorbs energy better than the white reflective side, the molecules of air move faster near the black surface. Molecules of heated air moving faster on one side of the vain than the other cause it to spin. Explanation and suggested experiments included.
