So there was this big tank that held a lot of molasses, which is a sticky brown gooey liquid that's made from sugar. The tank was in a city called Boston many years ago. But one day, the tank broke and all of the molasses spilled out super fast.
It was like a giant wave of sticky brown goop that was about 25 feet high and traveled really fast through the streets of the city. It knocked over buildings, horses, and people. It was really scary and very dangerous. People were trapped inside the sticky molasses and couldn't move.
It was a huge disaster and many people were hurt or killed. The molasses was so thick and sticky that it was hard for people to rescue each other. It took a long time for the city to clean up all the mess and people remembered this tragedy for a very long time.
