グリーンサイエンス - 飛行機モビール

I hung it in my son's window and the solar-powered rotors started spinning as soon as the morning sun hit them. It’s surprisingly sturdy for something so lightweight, and the gentle motion is really calming to watch.

Assembling it took maybe ten minutes, and once the sun hit those little solar panels, the whole thing started circling like a tiny satellite. It's genuinely mesmerizing to watch from my desk, and knowing there are no batteries to swap makes it feel like a tiny piece of the future.

I hung it in a south-facing window and it started spinning within seconds. The solar panel really works without any batteries, and the motion is surprisingly smooth for such a simple assembly kit.
