For a few hours last summer, a University pool was transformed into a body
of water that looked more like a fully functioning swamp than a swimmer's arena.
Members of the University swim team became field researchers in an effort to
settle one of the questions that has intrigued scientists—and swimmers—for
centuries:
What effect does the viscosity of a fluid medium have on the speed of a body traveling through it?
