"The Boston Molasses Disaster…occurred on January 15, 1919, in the North End neighborhood of Boston, Massachusetts, in the United States. A large molasses storage tank burst, and a wave of molasses rushed through the streets at an estimated 35 mph (56 km/h), killing 21 and injuring 150."
"The collapse unleashed a wave of molasses 25 feet (7.6 m) high at its peak"
"Several blocks were flooded to a depth of 2 to 3 feet (60 to 90 cm)."
