Microscopic Particles Form Strings

This 12-second video shows the formation of particle strings at angles perpendicular to the direction of shear flow. Many scientists had predicted that the strings would form parallel to the direction of shear flow. Experiments at Cornell and computer simulations at the University of Chicago show that the strings form perpendicular to the direction of shear.
