The movie shows the trajectories of particles in a two-dimensional granular material suspended in a single layer on a horizontal air table. Two samples are examined, differing only in their respective packing fraction, Ø = 0.77 and 0.79. In the first case the dynamics are diffusive, while in the second they are caged.
