At Balancing Ball, a plastic beach ball floats mysteriously several feet above a large plastic cone. Upon closer inspection, the ball is found to be floating on a stream of air blowing out of the cone, generated by a large fan beneath it. If the ball is pulled slowly out of the stream of air, a force is felt in trying to pull the ball back into the air stream. If the cone is bent to the side, the ball can be suspended in space off to the side of the cone.
