Observe the Power of Radiant Energy

Our Drop Radiometers will allow you to observe changes in the intensity of the Sun's rays and other bright lights by noting the varying speed of the spinning black and silver vanes.  The 6” long glass ornaments have an eyelet at the top for easy hanging in open spaces.
