G. I. Taylor's "Experiments with Rotating Fluids" examines the motion of solids and vortex rings in rotating fluids, comparing observations with theoretical predictions. Experiments showed that a cylinder moves straight through a rotating fluid, while a sphere is deflected. Vortex rings, which travel in straight lines in still fluid, follow curved paths in rotation

It establishes that slow motions superposed on a fluid already in solid-body rotation are two-dimensional, in the sense that material lines parallel to the axis of rotation remain so and material particles preserve their spacings along these lines
