High efficiency holographic diffraction grating film. This is the good stuff!
Great for making spectrographs, or taking photos with rainbows around every bright spot in the image.
A six inch square of it, so the whole class can make spectrographs.
With this film, you can see the bright line spectra of gases like Neon in your collection of the Periodic Table of the Elements.
