Experience this sphere powered by the sun! The vanes in the Radiometer are alternately dark and light in color. When the light strikes these vanes, it transfers heat to each one - but not at the same degree. The lighter vane reflects the rays and the darker vane absorbs the rays. The stronger the light, the more energy there is causing the vanes to spin faster.

Product review of Radiometer
Posted 8/7/2008 by Andre M. Bordelon

Rating: 

It takes intense direct sunlight to operate the instrument. This differs from other pricier ones I have seen.

Radiometer and Prism
Posted 3/26/2008 by Fred

Rating: 

We love the radiometer and prism we purchased through Fat Brain toys. Our 5 year old was amazed. He was so excited that he took them to show and tell at school to show all his class mates. I like to get him interested in science and the natural world. Thanks for offering products like this Fat Brain!

Radiometer
Posted 12/27/2007 by Christopher A. Wolter, D.D.S.

Rating: 

A fun little gadget that spins wildly when placed in direct sunlight. I had one of these as a kid about 35 years ago. It spun so many millions of revolutions over the years, that the spindle actually wore a hole through the glass thimble! A fun bit of nostalgia that I now share with my kids!

Tim's Radiometer Review
Posted 11/6/2007 by Tim Hughes

Rating: 

This product was exceptionally made and immediately sparked my children's interest in science and learning about alternative forms of energy. Comes in a very nice colored box with a narrative on the side of the box that explains about how the radiometer works and why. My children have used it inside and outside to see the differences in performance under different lighting. A very good buy at the price we paid. I would highly recommend this to others who would like to get their children interested in science.
