Part of a series of videos showing the glass transition in polymers, and the resulting change in energy dissipation on impact: Close up video at one tenth actual speed of ball bouncing well above Tg (i.e. when rubbery). The conformation of the polymer chains changes, and the deformation of the ball can clearly be seen.
