Recent experimental results from 4..pi.. detectors at the Bevalac are presented, with emphasis on the Plastic Ball. Heavy nuclei, in central collisions at Bevalac energies, stop in their center of mass producing a region of equilibrated, hot matter. Some of the energy is stored as potential energy of compression. At the same time the pressure builds up, producing a sidewise collective flow of nuclear matter. The system then expands until the density is reduced so that the chemical equilibria producing the light composite nuclei freeze-out, and then even further until the thermal two body interactions freeze-out. Each of these points are discussed. 9 references.
