The intermediate axis theorem states that an object can rotate around its longest axis or its shortest axis without trouble, but stable rotation around its intermediate axis will be impossible. It's hard to observe this on Earth, but Dr. Ben Longmier asked an ISS astronaut to try this for YouTube. Now it's the first post on [email protected] ! It only took 19 months.
I'm happy to be of service. I don't have enough gifs like this, but I'll keep an eye out for more to post here. I usually post these things in [email protected] with the tag #microgravity and my gif collection is focused on floaty things like that.
I forgot we even had a physicsgifs here on Lemmy. Does this even have a mod? I'd run this myself, but I'm on Mbin and I don't know if moderation works cross-platform.
