Cedilis 2 Pack 6 Inch Light Optical Glass Crystal Triangular Prism, Rainbow Maker for Light Refraction Spectrum Learning, Unique Photography, Science Physics Teaching

I love prisms! I used to have one when I was a kid, but since it was so long, and I've been exposed to so many Pinterest pictures of these vibrant rainbows coming out of the prisms, that I forgot that they are very light and transparent.It's still worth having one, they are really neat, and it's great to teach kids about refracting light.

fun prism high quality

The prisms were overall very nice, one had a couple of very small bubbles, but didn't detract the quality. The main problem was a film on the exterior. I started washing with alcohol, then dish detergent, and then de-greaser with no luck. Finally I tried WD-40 and it cleaned them both up to a perfect finish.

These are great, but as expected they are very fragile. The kids already chipped pieces off of them, but they still work great.

I was really delighted to find these. They are larger than expected and do an excellent job of refracting light into beautiful rainbows. I wish I had found them when I was still teaching. The price - amazing.

Cool prisms. Bought for son studying them in science but we quickly learned some tricks you can do with your phone camera and a prism.

Bought these for my kids to experiment on light reflection/ refraction principles. Too heavy and delicate for kids use. Got broken easily and hard to make rainbows . It would only refract and one particular angle. Was expecting better quality for this price.

This was shipped in layers of bubble wrap packaging to protect. High quality, blemish free, full size.. completely satisfied.
