WESTMINSTER, Colo. -- Pat Barry is standing over a large aluminum bathtub in his backyard, gripping one of those plastic dog ball launchers with both hands.
He has just poured an aggressive amount of ice chips into the tub and filled it to its brim with hose water. After letting the concoction sit, ominously, for several minutes, Barry begins to stir. The sound it creates is more jagged than you'd expect, because there's so much ice. Occasionally, for dramatic effect, Barry slaps the plastic launcher against the water's surface. Whhhtt!
