Kinetic Theory Model

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

An increase in the violence of vibration simulates an increase in gas temperature; and an increase in the weight of the 'float' also simulates an increase in gas pressure. Includes balls and two floats. Requires a power supply and standard wire plug, not included.
