oobleck fingers

Steve presented a neat paper at CPJC this week. He gave a cool presentation on granular materials. But the coolest part was the video:


They shook cornstarch in water (AKA oobleck) and saw some very strange effects. The authors explain the effects by shear thickening, which means that the viscosity increases at higher shear rates (i.e. when the fluid slides). That’s the same reason silly putty bounces when you throw it and oozes when you leave it sitting on the table. Shear thickening is an effect seen in some non-Newtonian fluids. It’s like a different universe!
