The Great Molasses Flood: When Boston Drowned in Sweetness

The Great Molasses Flood: A Sticky Disaster

Imagine a wave of molasses, thicker than any syrup you’ve ever encountered, surging through the streets of a bustling city. This isn’t a scene from a bizarre dream; it’s what actually happened in Boston on January 15, 1919, in an event now known as the Great Molasses Flood.

A Sweet Setup

The Purity Distilling Company owned a massive tank, 50 feet tall and 90 feet in diameter, located in Boston’s North End. This tank was used to store molasses, a key ingredient in the production of industrial alcohol. The alcohol was needed for munitions during World War I. The sheer size of the tank and the valuable contents made it a significant part of Boston’s industrial landscape. However, the tank was poorly constructed and maintained.

The Day the Molasses Broke Loose

On that fateful day, the air was unseasonably warm for January. As the temperature rose, the molasses inside the tank began to expand. Witnesses reported hearing groaning sounds emanating from the tank. Without warning, the tank ruptured. A colossal wave of molasses, estimated to be around 2.3 million gallons, surged through the streets at speeds of up to 35 miles per hour.

Chaos and Devastation

The impact was catastrophic. Buildings were crushed, vehicles were overturned, and the streets were coated in a thick, sticky mess. People were swept away by the viscous torrent, struggling to stay afloat in the overwhelming tide of molasses. The aftermath was a scene of utter chaos, with first responders struggling to navigate the sticky terrain to rescue victims.

The Aftermath and Investigation

In the wake of the disaster, an investigation was launched to determine the cause of the tank’s failure. The investigation revealed that the tank was poorly constructed and inadequately tested. The Purity Distilling Company was ultimately held responsible for the disaster, and lawsuits were filed on behalf of the victims. The Great Molasses Flood resulted in 21 deaths and 150 injuries. Clean-up efforts took weeks, and the city was left with a lingering sweet smell that persisted for years.

Fun Facts and Lingering Myths

  • Some people claim that on warm days, you can still smell molasses in Boston’s North End, though this is likely a myth.
  • The Great Molasses Flood led to significant changes in engineering and safety standards for large storage tanks.
  • The sheer force of the molasses wave was enough to lift a fire engine off its foundation.

The Takeaway

The Great Molasses Flood serves as a stark reminder of the importance of safety and responsible engineering. It’s a bizarre and tragic event that highlights the potential consequences of negligence and the unexpected ways in which industrial accidents can impact communities. The story of the Great Molasses Flood continues to fascinate and serves as a cautionary tale, reminding us to learn from the mistakes of the past.
