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!
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.
i saw a video of this engine in Tik Tok. it's quite cool. i bought it for my son to know more about science. it's ready to run. nice. i will buy more in the future.
I am so happy that I have chosen STIRLINGKIT. The machinery is particularly fine. The packaging is positive and durable. Yes, included in the box are extra parts and even they are protected beyond a doubt. I am so pleased to recommend this Ssite, STIRLINGKIT.COM, and anything that they sell. Thank You.
