A beach ball floating mysteriously in a stream of air, Balancing Ball enthralls curious children and adults alike. One of the most-visited exhibits at the Exploratorium, it explores the complicated ways that an invisible stream of air can interact with solid objects—like planes and birds—to make them fly. Join Staff Educator Zeke Kossover in exploring this exhibit and see how to make a levitating ball with a hair dryer.
