Try searching for your own micrometeorites by collecting particulates from roofs or drain spouts. Use a magnet to see if any particles are attracted, and discard nonmagnetic ones. Use your microscope to identify any rounded, shiny ones — perhaps with a pitted surface — or signs of a melted outer surface. If so, you may have found a micrometeorite.
