Solar Crookes Radiometer Glass Windmill Handmade for Party Home Decoration Toy Gift Blue S

Works well

Great conversation piece on my desk at work next to a Newton's cradle. The Crookes radiometer gives me an amusing opportunity to demonstrate wave-particle duality ... and listen to various alternate theories of how this device works.

Cheaply made but I did not pay for the more expensive one- so you get what you pay forIt’s so fun and fascinating. Great gift for any one of any age (8 & up probably?)

I love this item. I look at it everyday. It works with the sun. It puts a smile on my face every morning. It sits on my kitchen window sill.

It's a perfect window decoration for any nerd, or a conversation piece to introduce kids to everyday science. If I knew more nerds who cared for knickknacks I'd gift these in a figurative heartbeat.

This will be a gift for my grandson! Old school thoughts

Brings back childhood memories. Great to explain how it works with my kids!

Smaller than I expected and I have to jiggle it to get it started but then it works in direct, bright sunlight. Kind of disappointing. I had a larger one when I was a kid that worked great.

Fantastic desk item for the inner nerd.Great discussion starter.
