  1. A motor with no moving parts? What about all the parts clearly moving in the gif? Plenty of motors are actuated electromagnetically. Am I missing something?

  2. Applied current is making it form some sort of liquid version of dendrites? Or actual dendrites that revert to liquid when the current is removed?

    I’m nothing resembling an engineer. My best guess is it might have similar applications as ferrofluids to resist motion. Unsure what advantages it would have in that area though. Maybe more precise or rapid control over response?

    Edit: Also, iridium or indium? [GalInStan](https://en.wikipedia.org/wiki/Galinstan) is a well known eutectic. I’m not going down a rabbit hole to look up gallium-iridium-tin alloys.
