Surface Tension May Explain Fingering Patterns In Granular Flows

Recent experiments at the University of Illinois cast doubt on the theory that segregation of coarse particles creates finger patterns. Instead, researchers found evidence suggesting an effective surface tension generated by cohesive forces between grains may be responsible for the formation of these patterns.
