    Nice Educational Item

    This is a great educational and novelty item. It works as it should and is simple. It is not made to be abused, but to set in the Sunlight to function. I had one as a child 45 years ago. I wanted to relive my childhood.

    One of the best and simple Physics toy.

    Though it's a toy but not easy to understand. It's look very simply. But it's physics involved in it is complex. It works on... Thermodynamic. Gas laws. Newton's 3rd law And photon's force (Very minute) Wonderful radiometer to learn and see the power of Science.

    Radiometer

    It is inexpensive and was able to survive the US Postal Service, so it rates well in my book. It performs exactly as I expected it to do. Just as I remember from seeing as a kid.

    Useful science tool

    It's a nice little tool to show kids some of the wonders of light and the effects of different colors of the light spectrum on the vanes inside the device.
