M&M's Pack Tighter Than Gumballs

icantblvitsnotbutter writes "In a rather humorous article, the New York Times reports that M&M's pack more tightly than gumballs (registration, blah blah... alternate source here). The upshot of this is what it means for manufacturing denser glass (here, the generic term for solids made of random arrangements of molecules). Some basic solid geometry and tongue-in-cheek quotes fill out the story, but the immediate applications are mind-boggling for the next time you grab munchies on a road trip."
