The vanes, or wings, affixed to the center pole of this solar radiometer are alternately dark and light in color. When the light strikes these wings it transfers heat to each one - but not to the same degree. The lighter wings reflects the sun's rays and the darker wings absorbs. The stronger the light, the more energy present to heat up the darker side of the wing causing the wings to spin faster.  The scientific property that this elegant glass device demonstrates is heat transfer. The wings of the radiometer spin under natural solar light or a regular light bulb. Perfect for science projects, as a gift or as a desk amusement!

Features:

  • Elegant glass device uses heat transfer to spin its interior wings
  • No batteries are required; the radiometer is powered entirely by light
  • Either solar or indoor light works
  • Great beautiful desk toy
  • Excellent for solar science lessons
