Bead on a parabolic surface. At r₀=2.0 and ℓ~9.7 You get that ol bar trick where a bartender rolls a bead at just the right speed and it cancels out gravity.

Cool! Is your fiddle just the code? It’s not showing anything running for some reason…
Hmm, that’s unfortunate. It shows up fine on my end. I hardly ever use js fiddle, so I’m not sure what the problem could be.

Yeah, I think there was a time when JSFiddle didn’t work for me on Chrome, and I never looked into it. Probably not an issue on our end, lol.

It’s working in Firefox but not in Chrome. I suspect one of my extensions is causing the issue, since they introduced that Manifest V3, things have been breaking.
Still, pretty cool math tricks
