Source is YouTube and Institute of Chemistry and Chemical Technology SB RAS (PDF). If you have 2 kilowatts, a coil of copper pipe, and a lot of guts, you too could melt aluminum with induction heating while it's levitating.

Source is YouTube. No pressure, but I'm testing this against a different floating ball of water that I crossposted in !imaginary@reddthat.com . Good luck!

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 !physicsgifs@lemm.ee ! It only took 19 months.
