Sophia G. ★★★★★

The vanes start spinning within seconds of even indirect sunlight hitting the glass bulb. It's a mesmerizing little science piece that needs no batteries, just a bright windowsill.

Lily ★★★★★

Pleasantly surprised at how quickly the vanes start spinning once you set it in a sunny window. The glass bulb feels sturdy, and it's mesmerizing to watch the light energy at work without any plugs or batteries.

Adam ★★★★★

My kids dragged this onto the kitchen windowsill first thing this morning, and the pinwheels were spinning before our coffee was done. It's such a simple, clever way to see light energy doing its thing—no batteries, just sunlight, and it's oddly mesmerizing to watch.
