A simple demonstration of granular phases

[1principle]

Cool! I mostly liked concentation "jump" between thermostat and granular phase, which is increasing with temperature (I guess an analogy to Lengmuire or Knudsen jump of temperature and concentration at the distance order of mean free path from the boundary)

This model of hard spheres with the gravity instead of attractive potential - how it's real ?=)

Its like all susbtances that govern the universe are caused by vabrations. Depending on the vibration of molecules is how they attract or repel to create all the matter we know. Life is music. So vibrating string theory can be very likely to be true!
