Abstract
A child's toy having two parts, a tube part for directing a stream of air and a light ball which can be supported by the stream of air. The tube has a mouthpiece at one end with a cup at the other end. The cup has a slightly more concave curvature than the convex curvature of the ball creating an air space between the cup and the ball. A port in the cup connects the tube to the air space and biases the flow of air in one direction causing the ball to spin when the ball is offered to the cup and a stream of air is blown down the tube.
