22: Animation Charm (HP) (Spoilers)

Listen, I know I am currently having a lot of Ideas from Harry Potter right now, but hear me out.

So, the animation charm (Piertotum Locomotor). It is used to animate inanimate objects (mostly suits of armor). I was wondering... what CAN'T you animate? Molly Weasley used it on knives to cut up potatoes (according to the wiki). Does this mean that anything animated can float?

Maybe anything light? Does this mean flying swords? Even human sized gundams?

This charm has a lot of potential honestly. I mean even if objects can't float, you can still build things like mechs and animate them. AND I'VE NEVER SEEN ANYONE USE IT BEFORE. At least, not that I remember.

Dunno, in some cases, people just say that it is supposed to summon statues to your aid. (like in HP:Magic Awakend)

Off Topic: So uh, I've had a flu for the past week, im doing totally fine but my voice legit cracks all day. I mean, I barely talk anyways so nobody cares, but its annoying.
