Radiometer Sun Powered Scientific Device

This device detects and measures radiant heat energy. Alternating dark and light vanes transfer heat at different degrees, causing them to turn- the higher the heat, the faster they turn! Place on a sunny windowsill and watch the action. Educational and fun project for budding scientists.

For ages 8 and up.
