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.

As one of the top online toy retailers, we have access to unprecendented quantities of product review data. One of the key ways that we use this data is by associating our products to the specific ages and genders of the kids who are playing with them. Whereas most retailers must rely upon manufacturer suggested ages (i.e. 3+), we take actual customer usage and share it with you here so that you can choose the perfect toy or game.
But how does this help me? You can use these graphs as a general measure of it's appropriateness for a given age and gender. While this information is generally accurate, it should not be used as an absolute answer. For instance, many dinosaur toys are purchased for boys, however, that doesn't mean that it's inappropriate for a girl who happens to like dinosaurs.

 |
NOTE: The orange color in the charts above indicate ages that are LESS than the manufacturer suggested age. Please purchase at your discretion if your child is younger than 7 years of age.

This isn't exactly something you play with, but something that is educational and fun as it lets you see the power of the sun in action. I've bought several of these over the years to give as gifts and have never been disappointed in the delight it brings.

My little girl loves watching it spin. She even tells me if I didn't raise her window shade enough for her to see it.

(This will be used for a science class for 8th graders.) It works well , and as expected. The available literature seems to indicate that no definite mechanism has ever been proven for how it works.
