".2mL PCR tubes"

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

The Capillarity Apparatus is intriguing demonstration of molecular attraction.

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

Investigate the relationship between the speed of a fluid and its pressure

The Eddy Current Experiment demonstrates Lenz's Law.

Spectrum Tubes demonstrate the wave properties of different gases.

Dramatically Demonstrate that Temperature Increases with Pressure

Boomwackers are brighly colored plastic tubes tuned by length to musical notes.

High quality density cubes for the classroom.

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.
