The Spectarc Prism which hangs in the south facing window with the Owl stained glass is making rainbows this week. Sir Isaac Newton described the way in which prisms refract light and in that bending divide it into its constituent colors (wavelengths). So much mystery. I tried to see the planetary alignment yesterday. Failed in that quest, but it was good to be up and out on such a mild clear December morning. I bought this 10'' curvilinear plastic prism decades ago - can't find them anymore. It hangs from fishing line and when spun in a patch of sunlight it fills a room with dizzying arcs of our star's fireworks.
