The rose petals were traveling at high velocity and, apparently, behaving as though they were harder than whatever they hit.

Bella picks up a petal.

It is soft and silky.

"I wonder at what point in the process they lose their rigidity?"

"Probably when they lose their velocity."

"Makes sense."

"Do you think we could borrow a sheet of steel or something from Bar? I want to see how well hard metals hold up against this thing," Rose says.

"I mean, if you wreck it you buy it."

"...Does Bar even care if she gets it back broken? Worth checking."

"She doesn't care care, but she'll still put it on your tab."

"I might ask anyway, about chunks of iron or whatever that would only be good for scrap anyway so it wouldn't matter how many pieces it was in so long as the mass was the same."

"I don't know her policy on that."

She shrugs and heads back inside, repeating her query to Bar.

If shapeless hunks of metal will serve, then I will not add to your tab if they are differently shapeless when returned.

"That will do fine, thanks."

Bar produces a heap of shapeless hunks of metal.

And Edie...will haul them outside one at a time with her unaugmented strength, because if there's one thing besides despair living through five years of apocalypse will teach you it's stubbornness.

"...Do you want help with that?"

"Sure, if you're offering."

Telekinesis!

It will learn this lesson, yes indeed.

"...Thanks. To both of you. And--I'm sorry, again, for--at the beginning." She looks at the somewhat scrappier scrap metal. "I think I had better get this stuff back to the Bar and then go home."

"Good luck."

"Well, unless I'm drastically mistaken about what this spell can do, Iiiii'm about to go kill the Sentinel I was trying to hide from when I ducked in here."
