Molecular Motion Demonstrator

Turns abstract Kinetic Theory concepts into visual images, easily understood.

Reproduces molecular behavior in gases, liquids and solids with remarkable fidelity.

Realistically simulates changes in temperature, pressure and volume.

Operates on 110V AC with step-down transformer; solid state electronics; precision speed control.

Fits any overhead projector.

"I have never seen a better visual model for this type of motion."
John Baird, Farmington, IL High School

"No amount of arm-waving or talking can substitute for a first-hand "look" at dynamic molecular motion such as this provides."
