100 Pack 6 inch Crystal Optical Glass Triangular Prisms with Gift Box for Science Classroom

A triangular prism is a conventional optical component commonly used in other industrial equipment. The prisms we offer are used in science classrooms to teach children about optics.
This triangular prism is 150mm long and 30mm wide, but we can customize other sizes as an optics factory.
Also, this triangular prism can be used as a cool gift for your friends, just like our x-cube glass Prisms.

how your kids a rainbow with light refraction

Use a white paper or canvas and tack it to a wall across a room from a sunny window or a flashlight if there are no windows available. Make sure the canvas or paper is flat and smooth. Hold your prism in front of the background. Make sure to catch the light from the window. If using a flashlight, hold the prism in your non-dominant hand and the flashlight in your dominant hand. Turn on the flashlight and hold the prism in the light. Continue to twist and turn your prism in the light source until a corner of the triangle falls into the light beam. Light should then refract through the prism and create a rainbow on your background
