Rubber Magdeburg Hemispheres
Demonstrate the force of air pressure without a vacuum pump. The edges of the two 8.5 cm rubber cups are placed together and pressed to expel the air between them. Students discover the difficulty of separating the cups by pulling and tugging on the handles - providing an effective, 'hands-on' demonstration of air pressure.

Liquid Convection Apparatus
The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.
