The Great Molasses Flood of Boston

Imagine a giant tank of honey the size of a house. It was sitting in Boston on a sunny day in 1919. Suddenly, boom! The tank exploded like a popcorn kernel, but much bigger.

A wave of thick, brown syrup rushed through the streets. It did not splash like water; it rolled like heavy slime. Cars got stuck. Horses were lifted off their feet and thrown around. People tried to swim in the sticky goo, but it was too thick.

The tank was new, but it had tiny cracks. The sun warmed up the syrup inside, making it bubble and push against the walls. When the pressure got too high, the whole thing burst open.

It took weeks to clean up the streets. The air smelled like sweet tea for months. Scientists learned that metal can fail in strange ways when things expand and contract. Today, we still talk about it as one of the funniest yet most deadly accidents ever.
