A radially polarized filter is placed on an overhead projector stage and a regular (parallel) polarized filter is positioned above it. As expected, the image shows four quadrants, alternating light-dark-light-dark. When an optically active solution (corn syrup) is poured between them, the image rotates and separates into a beautiful array of spectrum colors.
