Demonstrates the difference in thermal conductivity of different metals. Consists of five metal rods stainless steel, brass, copper, iron and aluminum connected to a center metal, brass, hub which is mounted on a rod with wooden handle. The five rods have depressions on the ends to hold wax. When the center hub is heated, heat is conducted through the rods and conductivity of heat can be ascertained by the melting of wax.

Elasticity of Gases Kit
Elasticity of Gases Kit
15228

Serves to demonstrate Boyle's Law. Shows what happens when gases are subjected to increased pressure. The plastic syringe, with solid wood base and platen, is constructed so that the calibrations denoting interior volume read right side up. As masses of bricks, books, or other heavy objects are increased, the gas in the syringe is compressed to smaller and smaller volume. The kit includes: 1 Syringe Cylinder w/ Cap, 1 Syringe Piston, 1 Base, 1 Platen.

Fountain Connection
Fountain Connection
13452

Hero of Alexandria (c. 62 A.D) designed a water fountain that used compressed air to lift water to a point higher than its origin. Using your own soda bottles and this device, you can demonstrate the same principle. Water leaving the upper bottle creates a partial vacuum and enters the lower bottle compressing the air there. To balance out the pressure, air flows from the lower bottle to the upper bottle. The result is a spurting bubbling fountain that forms every time you turn this demonstration over. Additional experiments are suggested.
