This activity illustrates the relationships of mass, potential energy, and kinetic energy with marble races.

A set of four borosilicate glass tubes of different shapes connected together to illustrate that liquids will stand at the same level.

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.
