I found a powder in my driveway earlier today. I have no idea where it could have come from but I'm curious because it seems so out of place.
It's very dark brown, almost, but not quite black (see attached) and utterly uniform in colour.
It's extremely fine, finer than icing sugar. So fine that I can't even feel it between my fingers. Its granularity is perfectly uniform.
It covers very well. Rubbing it between my fingers gives me very black fingers.
It was in a little pile (about a teaspoon), near my car, very well-defined, as if someone had accidentally-yet-carefully poured it there.
I can't think of anything in or out of my car that would be like this. My neighbor is a mechanic, and has dead cars in our shared driveway.
Can anyone think of any cool tests I can perform on it to find out what it is? Obviously a microscope would be extremely helpful. I only recovered a tiny amount, a fraction of a teaspoon.
You know, it's got to be water-based powdered paint... It fits all the criteria. Except how it got there...
