The Coanda effect demo genuinely surprised me — you blow air across the curved piece and the ball just follows the bend instead of flying off straight. I've caught myself messing with it way more than the kid has.

My 10-year-old and I built this in about an hour and it was so satisfying

The build itself was surprisingly engaging—seeing the ball levitate using the Coanda effect made the physics click for both me and my nephew. Took about 40 minutes to assemble, and the instructions were clear enough for a beginner.
