As Will pointed out to me, this is a pretty crappy death:
Boston's Great Molasses Flood, which killed 21 people and injured 150...
...on January 15, 1919, a gigantic steel vat exploded, spewing 2.3 million gallons of molten molasses. Thirty-foot waves of gooey liquid plowed through the streets, catching men, women, horses and vermin in its sticky flow, crushing freight cars, wagons and automobiles and reducing entire buildings to broken planks of wood.
Who knew. Also who knew that molasses was used to make ammo. Moving on....
