Svævende lanterne

The tension-and-rubber-band mechanism is genuinely clever, and when I finally balanced the lantern above its base, it really looked like it was defying gravity. My kids and I spent an hour tinkering with it, and the science explanation made it feel like a mini physics lesson. Worth every penny.

Watching the lantern hover above its base using just rubber bands and tension genuinely made me stop and stare — it really does look impossible. The build itself was straightforward and the floating effect held steady once I balanced the bands right. My kid and I have already rebuilt it three times

The rubber band tension mechanism is way cleverer than I expected—my kid and I built it in one sitting and spent the next hour testing how high we could make it float. It genuinely teaches the physics while still feeling like a fun project, not a lecture.
