Fluid dynamics met history for a team of researchers who studied the Boston Molasses Flood, a disaster that claimed 21 lives, injured 150 and flattened buildings in the Commercial Street area of Boston in 1919. A trio of fluid dynamics physicists explain how they were inspired to study this event by a group of undergraduates who produced a parody rap video about the flood for a project in their fluid dynamics course. The trio examined this historic, yet not well known, event from a scientific perspective.
