Granular Materials


Granular materials--like sand, rice or powdered pharmaceuticals--are everywhere, yet their behavior is poorly understood. In some ways behaving like liquids, in other ways behaving like solids, such materials have unique properties and pose unique questions to answer. From clogged coal hoppers to powdered-snow avalanches, scientists and engineers are gaining new perspective on the fundamental nature of grains. In this video, see some of the latest research into the behavior of granular materials.
