The way the vanes start spinning immediately when direct sunlight hits them is genuinely mesmerizing. I’ve been using it as a centerpiece on my desk, and the glass construction is much sturdier than I anticipated. It’s a perfect conversation starter that actually teaches you about light energy.

The sunlight hitting the vanes makes them spin so smoothly, it’s genuinely mesmerizing to watch. I’ve had it on my desk for a week and still catch myself just staring at the rotation.
