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.

Visualisation of force chains through polarisation of light in a plastic is so obvious, yet still mind blowing

How interesting granular materials are!

Hi! Would it be okay to use a screenshot from this video for an open access textbook (it's part of our NSF broader impacts)? Happy to send more details, I just couldn't figure out how to reach out privately.

Interesting video!

Does anyone know what the particles are at 1:24?

[@bottlekruiser]

I think they're plastic cylinders.

hi anyone here for science class?
