If your school is within driving distance of Delaware
or you plan to travel nearby, consider visiting
the Brandywine River Powder Mills at the
Hagley Museum
were designated as a National Historical Landmark in 1966 and
as a Historic Mechanical Engineering Landmark (in 2002 Oct)
by the American Society of Mechanical Engineers (ASME).
For many decades these mills produced the DuPont Company's
main product -- black powder for guns and explosives,
and the docents provide an excellent survey of many aspects
of powder technology as they guide visitors through the renovated mills
and the museum of industrial technology.
