Polygonal kitchen sinks

I heard about this study in Nature (subscription required) in a recent talk. See some pictures here.

When a water jet strikes a flat surface at high Reynolds number, it normally creates a circular hydraulic jump. In the paper linked above, Ellegaard et al. demonstrate that stationary polygonal patterns can be formed (instead of circles) when high viscosity fluids are used.

Great thoughts you got there, believe I may possibly try just some of it throughout my daily life.
