"micro tube racks"

This large rubber hammer is ideal for activating tuning forks.

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.

Gram Centimeter Plastic Cubes

The Air-Cooled Laboratory Rheostat is the classic lab solution for controlling voltages and currents.

Demonstrate Bernoulli's principle.

For class model building.

The high-frequency coil can be used to test vacuum equipment for leakage or excite electrical tubes for demonstrations.

Fine hand instrument for qualitative visible spectrum analysis.

Lower Frequency Than Traditional Forks

This bell jar demonstrates that sound waves can't travel and therefore can't be heard without air or matter.
