When viscous fluid is displaced by a less viscous fluid in a thin layer, a fingering instability forms, known as the Saffman-Taylor instability. In this case, dyed glycerin was displaced by water, and then by air, inside a Plexiglas sandwich. This image was created for a unique course on flow visualization that combined engineering and fine art photography students, faculty, techniques and concepts.
