Chemical Avalanches

A chemical wave front resulting from molecular diffusion and a chemical reaction. 

Researchers have generated wave fronts from a balance between molecular diffusion and a chemical reaction. Starting from the top of the image, the wave propagates toward the bottom edge, and the colors in the image indicate velocity spatial fluctuations.
