Spatula Tzar, who brought us the controversial fly plane, offers a number of other interested projects, including this ball mill (a device used to crush metals and chemicals into a fine powder), made from mainly junk lying around the lab.

    United Nuclear also has plans for a ball mill on their site. Or, they’ll sell you a commercially made one.

    But you should make your own on principle.
