Easy to make visible light spectrophotometer using a pringles potato chip can, old CD rom disc, piece of baking tray foil, tape, and a piece of matt black paper. Can be made in about 15 minutes. In this video, the spectrometer was tested with white light from a CFL, "black light" from a CFL, light from a neon bulb, light from a red LED and light from a white LED. The matt black paper is important to prevent internal reflections from the silvered interior of the Pringles can.
