Prism Cube

6 Sides and a Spectrum of Light

This prism is more than a beautifully cut piece of lab-grade, K9 glass. It’s a useful tool for analyzing and reflecting light. Watch this small cube transform white light into a myriad of colors on the light spectrum.

When you open a prism’s case, the embedded LED bulb auto illuminates, giving the prism a chance to bend light. Behold the index of refraction as light bends through the prism and its various precise angles and plane faces.

Whether you put it for display by the window, scattering rainbows across the walls or leave it set in its protective case with the built-in light shining on it, you’ll be able to witness how the light changes and observe the same light experiments Sir Isaac Newton did hundreds of years before.

Measures 0.75” x 0.75” 0.75". Includes prism and carrying case with built-in light. For ages 14+.

About K9 Glass:

K9 glass, sometimes referred to as K9 crystal, is a type of optical borosilicate crown glass. The K is in reference to the German word for crown and the 9 refers to its 9% lead content.

K9 glass is high quality, lab grade. It has high optical clarity and is difficult to cut due to its superior properties. Its high refractive index makes it desirable for telescopes and prisms.
