Although air is present in the room with other matter, a visual aid is necessary for an observer to "see" that air occupies a portion of space. In this experiment, a plastic cup containing both air and a crumpled napkin is turned upside down and placed into a container of water. Air and water cannot occupy the same space at the same time; therefore, the napkin remains dry.
