Can I ask why we're using a special definition of "levitation" that doesn't really mean levitation? I'm finding it very annoying to click headlines that say "Levitation of LK-99!", and... ohh it's still standing on one end.

I'm sure this is a promising discovery and everything, but saying "levitation" at this stage is very forward-looking, and for me - a bit cynicism-inducing.

I would assume that this is because of the lack of purification of the samples.

A fully pure sample would probably fully levitate. Given the rush to recreate and lack of purity, if a portion levitates (causing standing on one end) you could assume a pure sample would fully levitate.
