Offer audible proof in the course of a demonstration of the effects of atmospheric air pressure. A Plexiglas cylinder is sealed off on one end by a plastic membrane then placed on the vacuum experiment plate U21850. The air occupying the space in the cylinder under the membrane is evacuated. The plastic membrane implodes with a loud ...
