"tube coolers"

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

Demonstrate the free-fall motion of objects in atmospheric pressure and vacuum conditions.

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

Students measure pressure with a precision manometer.

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.

This Ballistics Cart demonstrates the independence of vertical and horizontal motions.

Gram Centimeter Plastic Cubes

Compare the falling rate of a feather and a guinea (coin) with air resistance and in a vacuum.

The Capillarity Apparatus is intriguing demonstration of molecular attraction.

Dramatically Demonstrate that Temperature Increases with Pressure

Students determine the adiabatic coefficient of air.

The Centripetal Force Kit is inexpensive and effective.

Ensure perfect geometric alignment of your balsa fins on any Estes model rocket.

Add some tech power to your rocket experiments and take the guesswork out of altitude measurements.

Demonstrate Bernoulli's principle.
