After seeing it I can accept that the rotation lines up the holes.
But i never would have thought of it.

uhmm, enlighten me as to how the holes get lined up....

Pretty simple really there are microscopic gnomes running pell-mell along the rotating shafts aligning the beads up as the run by.
No seriously it is a matter of the center of gravity by rolling the beads the absence of a center mass say from pole to pole means the greater mass is along the equator the gyroscopic effect will cause the bead's equator to seek perpendicular tp the axis.
But I kike the gnomes better

OK, makes sense now.
The gnomes theory actually sounds better.

Great explanation Frank. Very clear now, but I had no idea before you explained it.

Frank S seems to be one of those clear-eyed devils. Able to take in all the variables — at a glance — and immediately account for their overall effects. On the situation ... around the area. That — or he has massive amounts of experience, under his belt.

Kudos, Frank.

I like the clear eyed devil analogy LOl.

Physicists describe it as polhode motion. This article...

https://en.wikipedia.org/wiki/Polhode

describes it in detail. This quote...

any rotating body will continue to change its orientation until it has stabilized around its axis of maximum inertia, where the amount of energy corresponding to its angular momentum is least.

from the end of the article sums it up nicely.
