This is a very cute device. It works extremely well and demonstrates solar energy and magnetism. Again, it works extremely well. I have mine on the window sill and I enjoy watching it every day!
This device demonstrates how super magnets can levitate an object and also how solar energy can be used to make mechanical energy. Great fun to watch!
Really like this thing but it does need a lot of light to function properly. But when it's working, it's very cool.
Very cool grandkids love it.
Very nice gadget. It’s not perfectly balanced and wobbles slightly (not bad at all) at a couple of rotation speeds. At most speeds and in direct sunlight at its highest speed it’s rock steady. There was no assembly or setup required, it ran right out of the box.
