Newton's Prism

Recreate Newton’s famous prism experiment on a large scale. Rotate a mirror to redirect natural light from the Museum's rooftop heliostat mirror into one of four giant optical prisms. Just as Newton demonstrated, the prism splits white light into its component wavelengths. The result? A huge rainbow, brilliantly reflected on 30-foot-tall white screens.
