 Telescope makers use it to make small "pin holes" in photo graphic
plates and film. You smash some and it makes hundreds of tiny specs
that are almost perfectly spherical. These cast shadows on the the
photo material. The film that is exposed turns dark, leaving the
tiny clear spots. One simple mask off the ones that are not used.
