Part 2: Learn how to build your own CD spectroscope using a few simple materials and our special cutting guide.
Turn an old CD into a spectroscope to analyze light-you may be surprised by what you see. Try pointing your CD spectroscope at the fluorescent light in your room, sunlit clouds in the sky, even your friend’s colored shirt to reveal the wavelengths of light that mix together to create the color you see!
