Abstract of the Disclosure A toy comprising a very light ball in a tube. One end of the tube is for placing to the lips to blow toward a cup fixed at the opposite end. The cup has a concave surface which receives the ball which extends over less than half its surface. When the ball is placed beneath the cup and held in contact with it, in a steady stream of air expressed from the cup, the ball is trapped by the air stream and remains in close proximity to the cup. Preferably, the clearance between the ball and the curved surface of the cup is greater at the center of the cup. Preferably also air is expressed from a central port which is relieved or chamfered in one section in order to bias the escaping air, causing the ball to spin. The cup may be asymmetrically located about the port such that it is canted in the direction of the relief or chamfer so that the escaping air follows a slightly longer path before it escapes from the lip in said one direction than in the other direction.
