I've never actually handled that stuff, but I'm sure that it gets
everywhere, makes a mess, clings electrostatically to everything, and
gets readily into your nose and mouth and lungs, as you've described.

And if it didn't do all those things, it wouldn't be physically
accurate regolith simulant.

I'm sure it probably tastes and smells like black powder, too, just
like the Apollo astronauts described the smell of real regolith.
