- MaxLeiter 10y agoI think anyone that's taken highschool physics has as well
- tzar 10y agoYes, they've known about preventing puncture due to weight distribution, but this article is mostly about a different kind of bounce where the balloon (or water droplet) preserves its flattened shape even as it achieves clearance from the nails.
- lordnacho 10y agoThis is a good reminder that there's research to be done in classical physics and engineering, not just fundamental particle stuff. Even though we know (or think we know) how things like force, pressure, tension, etc work at this scale, there's still explanation to do.
