The Weissenberg effect is a phenomenon that occurs when a spinning rod is inserted into a solution of elastic liquid. Instead of being thrown outward, the solution is drawn towards the rod and rises up around it.[1] This is a direct consequence of the normal stress that acts like a hoop stress around the rod. The effect is a common example of Non-Newtonian fluid dynamics, which has been shown to occur for polystyrene.[2] The effect is named after Karl Weissenberg.
