[00:00:00]Did you know that molasses once killed 21 people in Boston? January 15th, 1919.

[00:00:07]A normal Wednesday in the North End.

[00:00:09]Then a 50-foot tank holding 2 million gallons of molasses exploded. A 25- ft wave of syrup crashed through the streets at 35 mph. The sticky tsunami crushed buildings like paper, threw trucks into the harbor, buried entire city blocks. But the real horror wasn't the destruction. It was the drowning.

[00:00:28]People trapped in the molasses couldn't move, couldn't breathe. The syrup filled their lungs as they suffocated. Rescuers watched helplessly as victims sank deeper with every struggle. The more you fought, the faster you died. Some survivors were found days later, still stuck to sidewalks. Still alive, the company had ignored warnings for months.

[00:00:47]The tank leaked so badly that children collected molasses in buckets. But corporate greed turned a sweet treat into a weapon of mass destruction.

[00:00:56]Boston Harbor stayed brown for 6 months.
