Review on 🌈 Optical Triangular Spectrum for Enhanced Physics Instruction by Seth Torres

I expected the glass to be thicker. I bought 2 prisms to show my students in class how white light breaks up into different colors in the visible spectrum, but it doesn't. well, one more thing. I don't know if this has anything to do with size or quality, but another prism I bought (from another company) worked amazingly.
