## Description

20mm RGB Dispersion Prism Optical Glass X-Cube Prism for Teaching Light Spectrum Physics- Gift of Light

Review: I gave this to my son for his 4th birthday. He's had it for over 2 months now and still likes to carry it around and show it to people. It is both educational and beautiful. The crystal is very clear and when you shine a flashlight (or sunlight) through it on one of the correct sides, it beams colored spectrum light onto the surrounding walls/room. The crystal has 2 crisscrossing planes inside of it that form a 3-dimensional X within the cube. These provide the refracting capabilities and also why you have to shine the light in the correct direction through the crystal for it to show the spectrum. Overall, a neat gift to give to a child which can also be used to educate them on the light spectrum.
Review: Exactly what I was looking for. This trichromatic cube is on the smaller side, but still demonstrated light refraction of different colors of light as you rotate the cube. My students were mesmerized. It was absolutely worth the cost. Now I want a 2nd one to show the secondary light refraction!
