This package of plastic pulleys contains 25 each of 20, 30 and 40 mm diameter pulleys with 3.2 mm bores and one 10 mm pulley with a push fit to a 2 mm motor shaft.

High Quality and Economical

The Ballistics Car demonstrates an integral law of motion.

Build 5 simple machines simultaneously!

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.

With the Large Plastic Dynamics Cart, students can explore the changes in motion that occur in a dynamics cart when different amounts of net force are applied.

Versatile teaching kit contains enough materials for the whole classroom to learn about and experiment with a variety of pulley configurations. Because these activities are hands-on, students get a real feel for the forces at work.

Ideal for tensioning lines.
