Fun!

I have used these for years to teach the wave nature of light and sometimes with additional equipment to help students understand spectra and how we use them in different science fields. And they are just Fun!

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.
