    Cylinder Marble
AI Thread Summary
A new video related to an old discussion on marble spiraling inside a cylinder has sparked interest, particularly regarding basketball shots that bounce off the rim. Observers noted that a basketball can appear to rotate around the rim before either falling through or bouncing out, with some suggesting that the center of gravity may dip below the rim during this process. Steve Mould's follow-up video explores this phenomenon using a bouncing ball as a model for rolling in a cylinder. Participants in the original thread are encouraged to revisit the discussion for further insights. The connection between the new video and the previous physics concepts enhances understanding of these dynamics.

Huh, very interesting!

Sometimes when I'm shooting basketball hoops, my shot will be off-center but inside the hoop. If it catches the rim just right (just wrong?), I can see several rotations around the inside of the rim before the ball finally falls through or gets spit back out. Several times I could have sworn that the center of gravity of the basketball was below the plane of the rim before it got shot back out, and maybe this video shows an explanation of why that can happen. It will still be frustrating to miss like that, but at least now I'll know why...

With a contributing video from you, which inspired this one, if I may add ;).

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
