	Radiometer A great conversation piece that demonstrates important energy concepts.
	Convection of Gases Apparatus Apparatus consists of a metal box with a clear shatterproof acrylic front panel, two glass chimneys, candle, and a cotton-filled wick as smoke source. Instructions included.
	Density Cube Set Choose from sets of 10 or 4 specimens.
	Ball and Ring Apparatus Demonstrate thermodynamic properties of metal with this classic experiment. All brass construction, with black lacquer finish wood handles. Includes instruction sheet.
	Heat Transfer Apparatus Observe and measure the transfer of heat by an aluminum bar between two water samples of different temperatures. The two insulated containers have foam lids and mounted thermometers.
	Bimetal Strip (Compound Bar) Quickly and easily demonstrate thermal properties of matter!
	Buzzer In Vacuum Apparatus Sound cannot travel through a vacuum. Demonstrate this with the classic "bell in jar" experiment. The bell gets fainter as air is pumped from the jar and pressure decreases.
	Elasticity of Gases Apparatus This popular Boyle's Law experiment comes with a low cost. Pressure versus the reciprocal of the volume are plotted as uniform masses are added to the top platform in search of a straight line.
