For a really cool video from the International Space Station about a phenomenon related to the spinning plate stuff, see here: Dancing T-handle in zero-g, HD

  That is really interesting. I know it's not correct to simulate rigid body dynamics as constant unless an outside force is applied, but what to do differently is not obvious to me. That looks like the object changes orientation while it's world-coordinates momentum vector remains unchanged. Got any references for why that happens? I mean orientation changes regarding the flip, not the obvious spinning motion.

    Not me. I only understand half your post, to tell you the truth. But Derek Muller on the youtube channel Veritasium has a good video on this, where he mentions how, when asked one time, Feynman couldn't think of a simple way to describe how it works, and then Muller goes on to explain it in a way that I could see. Great stuff: https://www.youtube.com/watch?v=1VPfZ_XzisU https://www.youtube.com/watch?v=1VPfZ_XzisU
