Cost Effective Diffraction Grating

Rainbow Peeps are easily the most cost-effective means of providing students with a simple tool able to reveal the spectrum of color present in white light. They are sturdier and less expensive than cardboard glasses fitted with diffraction grating. A class set of these can last for years - but for just a few dollars per class, they can be sent home to allow students to share what they have learned with their family. A terrific addition to any lesson featuring the famous Roy G. Biv, or even more sophisticated investigations into what we can learn from the spectrum.
