      Learn about radiant energy (heat) with this cool device! Radiometers were invented in the mid-19th century to measure the intensity of radiant energy. The vane inside a glass bulb spins as light hits it (the rate of spinning varies with the intensity of light).

      The kit comes with an assembled radiometer and instructions with scientific explanations of the phenomena and six experiments.
