Diffraction Grating Glasses - Educational

I have bought a set for everyone of my chemistry students in the last 5 years. We use these to talk about waves and light when we introduce electrons. They use these to look at light from flame test labs as well as the gas discharge tubes. I tell them to take these home and watch fireworks with it. This may be the last year of giving them out, but I will have several pairs for students to use in the same unit of study.

I have just retired after a five decade career of teaching Astronomy, Space Science, and related topics in planetariums and science centers. For almost three of those decades, I have been using these diffraction grating glasses to teach about light, spectroscopy, emissions from spectrum tubes, distance to stars, red and blue shift, the Doppler Effect, etc. My latest purchase is for my friends to watch fireworks through on the fourth of July at our annual party. We have been using them at our party for the last eight years!

My students enjoy learning about energy-color looking all cool and getting a better understanding about the whole electromagnetic spectrum!
