A series of vehicle crash tests was performed by the Jet Propulsion Laboratory (JPL), California Institute of Technology, to evaluate and demonstrate the performance and effectiveness of a low-speed barrier designed by JPL. The JPL barrier is a configuration of empty aluminum beverage cans contained in a tear-resistant bag, which in turn is encased in a collapsible container made of plywood and steel. Static testing indicated the compressing of one 12-ounce aluminum beverage can will dissipate 28 ft-lb of energy at 72 percent compression. Vehicular crash tests indicated that the dynamic energy dissipation per can was substantially higher - about two or three times - than the static. Seventeen tests were conducted with a driven vehicle at NASA's Jet Propulsion Laboratory. The light-weight can-filled barrier was very effective in softening the impact of an automobile in head-on and off-angle collisions.
