Review on 📸 Exploring the Spectrum: Triangular Photography Experiments for Teaching by Kent Kings

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.
