Do you know of anyone trying this and actually finding micrometeorites?
Nope. I have never tried this, but it just sounds like a fun thing to try some time. It's been a while since I have cleaned my rain gutters....so maybe I will mix a little fun in with a tiresome chore. ;-)
I don't know who figured this little process out, but it does make sense. What a thrill it would be to actually find some little particles that are rounded and pitted!
