I am a high school chemistry teacher. When we cover the electromagnetic spectrum, we do a lab with these and the kids LOVE them. The kids enjoy them so much that each year I buy more as prizes for kids who do well/ show improvement. They get so excited when they get one! Absolutely love these and highly recommend.

I've shared it with people and it's fun seeing the reaction to the diffraction hahaha 😂

They diffract, they fit on your head. Kids and adults find them amusing. They were a great price.

Bought these to hand out at a music festival and seeing the excitement of the kids young and old was well worth the money! Next time I’ll buy more it was that much fun. They worked. Not flimsy. Get’em.

One got handed to me last year at Electric Forest and now I stick a stack in my camelback whenever I'm outside and lights are bright and people are having fun -- feelsgoodman.jpg

Perfect for use in and out of the classroom. My 8th graders loved them, and even 12th graders seemed impressed. A must have for any teacher who teaches the EM spectrum, etc. Great gift for little kids, too. Seriously, an all around crowd pleaser that lets people understand that white light is really all the colors of the rainbow. Great stuff!
