    Its not stable, the liquid inside spins in different angle, thus making the object flip, stop, then, liquid flips, stops, object rotates, and on and on... Look at liquid filled bottle...Both axis are trying to dissipate energy until both stops. The universe wants to stop...

    I think your video was very good, but the explanation for this effect is hardly intuitive. My definition of intuitive is if you can explain a concept to a layman on the subject in one sentence. Is it not imperfections of symmetry that eventually resonate with centrifugal forces and cause the flip?

    A theory of mine Nothing is ever truly balanced, due to this it will induce a wobble, thus will cause the body to find its lowest state of inertia on that axis. Because the body will not just start to rotate on another with its true lowest state of inertia axis it will flip?? As for fluid in a cylinder; Ultra Laminar Reversible Flow could explain this phenomenon.

    Even if a body the size of a planet like Earth had the necessary distribution of mass to "flip" ... how long would it take? I doubt it would do so as fast as a small object like a wingnut or a tennis racket. It might take years or even centuries, so it might not be as violent an event as people fear. Or it could be that the gravitational field of masses that large pull this distribution into a stable state which can't flip. Someone should design a computer model to determine which possibility is more likely.

    Even in environments with gravity, the nuts won't just spin proportionately to how hard you apply a twist inertia to it. One would assume it's just the friction of the bolt it's still on that's causing it to lose momentum and then we just notice it fall off at the end of the bolt from gravity, but it seems to spin a pretty consistent distance regardless of how hard you apply inertia (beyond a certain minimum level) and then just stops- which it now seems is because the bolt is just in the way preventing it from the 180 flip. Anyway, your model suggests that it's a slight imperfection in the application of force (without internal energy regulation) that just gets magnified. Would the Dzhanibekov effect not happen if that slight off-axis bump were avoided by precise force application? And you said that Earth doesn't flip because it has internal ways of dissipating energy. So... a planet without such means of dissipating energy would have the flip risk then? It'd have to be a planet without any surface volcanic activity and a consistent enough atmosphere that it doesn't really have changing weather. But then what about things like axis tilt and moons? And inhabiting organisms for that matter. There's a neat sci-fi-concept in this somewhere.

    So if you had a mass that had three discrete moments of inertia, an impossibly perfect and symmetrical distribution of mass and volume, and was uniformly accelerated axially around its intermediate axis, and had no means of dissipating its KE, it would not exhibit this phenomenon? It seems it is a seed instability/mal-alignment that fuels the explanation for the periodic orientation inversions.

    The is the reason they are melting the polar icecaps under guise of "climate change" that is created by geoengineering schemes. When the icecaps get to a certain density the poles flip and its pretty much an ELE for most of earths inhabitants. They don't want the truth to get out because of the mass chaos it would create.

    ACTUALLY, There is a book called the Adam and Eve story that was banned, sanitized and re-released by the CIA a bunch of years later that talks about the Earth flipping, not exactly how the intermediate axis theorem would predict but I was thinking it has something to do with it. Also, the explanation of the theorem you gave with the 3d animation wasn't an explanation at all it was just a description.
