Ideal for exploring force of friction.

Demonstrate how the frictional force on an object depends on the surface, not mass.

A dramatic visualization of air pressure. This 1000 ml bottle has a balloon attached to its neck and an additional hole in its base fitted with a rubber stopper. You cannot inflate the balloon with the stopper in place, but remove the stopper and the balloon easily inflates. Replace the stopper, fill the bottle with water, remove stopper and Whoosh! – a geyser erupts!

Demonstrate Principles of the First Commercially Produced Steam Engine.

Transparent steam engine for demonstrating how an oscillating steam engine operates.

Conductometer with variety of metals to demonstrate heat conductance by various metals.

High Quality for the Classroom.

Demonstrate the speed of heat conduction in five different metals.

Demonstrates thermal conductivity differences between materials.

Employs Guericke’s Method for Demonstrating the Force of Atmospheric Pressure.

Demonstrate the Force of Air Pressure Without a Vacuum Pump

Ideal for demonstrating that vapor pressure increases when temperature increases.

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.

This nickel coated plate uses a rubber pad to achieve air tight contact with a bell jar. It features a stopcock and center hole with safety screw plug and a rubber gasket.

High Quality for the Classroom.

Demonstrate how the Second Law of Thermodynamics can create electricity.
