The exhibit consists of a six foot high glass cylinder within which is a one inch thick layer of water containing an agent for visualizing fluid flow. Within this cylinder is a motorized rotating cylinder. As you spin the inner cylinder, fluid flows in complex, self-organizing patterns. The exhibit demonstrates a phenomenon known as "Taylor Instability" named after the British physicist G.I. Taylor who was able to predict this instability mathematically.
