Pat Shingleton for Jan. 11, 2013 Pat Shingleton for Jan. 11, 2013 Advocate story Jan. 12, 2013 Comments Today marks the anniversary of “America’s most fascinating and surreal disaster.” As noted in a previous column, on Jan. 11, 1919, Boston’s Daily Globe reported “a cold air mass settled in.” The following morning, the mercury tumbled from 36 to 20 at 2 p.m., then to 7 at 10 p.m., then 2 degrees. Crews from the ship Miliero pumped a half-million gallons of molasses from its warm hold into tanks holding existing cold molasses, causing a bubbling churn and vibrating the tank’s walls. Workers reported the walls groaned. This process activated fermentation, aided by a temperature rise to 50. Then the top of the 58-foot tank blew and a 50-foot wave of 2 million gallons rushed over the streets killing 21, injuring 150. Fastcast: Springlike.
