View submission: Is sand a liquid???
Ahh i see. Sand in air sounds more like a suspension than a "phase" of a pure substance (like liquid). Maybe comparing it to a liquid is not the best way to think about it.

That's kind of the point, granular media and suspensions expand the idea of "phase" beyond the solid/liquid/gas triad we learn in grade school. We'd like to think of them as continuous smooth media, but they're not, so it gets complicated.
One way to think about it is that a granular medium is a suspension stops being, well, suspended.
