[Padparadscha just waves a hand as if to indicate that yes, the touching was already a failure. When he throws the rock, though, Padparadscha is prepared to catch it, using that same hand to cup it out of the air. Even with that fairly gentle motion, it chips a tiny bit off the pebble.]

Ah, well, I broke it a little, but that's just because I don't think this is a very hard kind of rock compared to me. [Padparadscha opens their hand to show it - it definitely doesn't look like anything magical, just the result of something hitting something that outclasses it in hardness, knocking a tiny fragment off.]

Did you think I was going to burst it in the air? [It's a funny thing to think about, admittedly, but perhaps not the most likely thing he was testing there.]
