"gel box"

This Ray Box is a simple, safe, and sturdy source of projected light for many classic optics experiments. Best of all, you don't need a completely dark room to conduct optic experiments due to its high-intensity light!

No need to Buy New Magnets

This updated Ray Box uses five super bright LEDs for bright, white rays that are clearly visible.

Sturdy box for investigating frictional forces.

This ray box is ideal for optical demonstrations in the classroom.

This condenser box provides different values of Electrolytic capacitors, ranging from 1μF to 4.7μF. Built on a 8 x 5" plastic box. All these capacitors are of ± 10% tolerance and are of 63 volts working voltage.
