Colloids and the depletion interaction

Animation of depletion effects in colloid-polymer mixtures that occur in systems such as food and paint. The non-adsorbing polymer chains induce an effective attraction between the colloidal spheres. Above a certain polymer concentration this can lead to demixing.
