📸 Exploring the Spectrum: Triangular Photography Experiments for Teaching Review

Far exceeded my expectations. The prism is well made. Everything from the prism and the price of the prism to the packaging and speed of delivery is highly appreciated. What I received is a well made, highly rated optical prism. Very impressive! I advise.

These cute glass prisms serve as the basis for many scientific activities. They are a great size for classroom or home use. When some of my original orders arrived broken I sent them back and Pannio immediately sent replacements. All spare parts are perfect!

I bought these to put in my new room so I was so excited when I bought them. I ran outside when I saw an amazon. I immediately opened my prisms and tried them out. I was amazed by the hat I saw because I think science and prism are cool. It's really cool to see how a prism turns sunlight into a rainbow. I can't wait to put them in my new room!

Looks like they were roughly cut from a long piece of extruded glass. The finished edges are straight but the ends are not square. do not line up in a vertical position. Also, I assumed 1.97 inches referred to the finished face (they look square in the photo), but that's just the length. The width (which is the most important part) is only one inch. Came in a nice box, I will not buy again.

My preschooler did a rainbow/prism lesson while we were in distance learning. We thought it would be fun to have something that we could literally see the effect of at any time, whether we had a rainy day or not (which doesn't happen that often in our house). Those cheap little prisms were just a gimmick. They were well packed in a gift box. Certainly provide plenty of entertainment and education for years to come.

Made a rainbow which was my main goal. The weight is good and it feels like a solid product. But one of the prisms is cracked inside (smooth to touch but looks tactile). And I was disappointed with the packaging. The red decorative box it came in was sealed with tape and ripped when I opened it. For the price I'm happy to get a decent Prism but I could be happier. Instead of keeping two crystals in a padded display case, I just leave one on a separate shelf.
