When Part of a Major City was Destroyed - by Molasses

2.3 million gallons of molasses were in a 5-story high tank in Boston’s north end. On a cold winter day in 1919, the tank collapsed, sending a 30-foot-high wave of molasses throughout an entire neighborhood killing 21 and injuring 150. The disaster led to the first class-action lawsuit in U.S. history. And, the smell of molasses lingered for decades.
