The neck portion is the only connection between the inner and outer chambers and comprises a flexible tube for permitting the inner chamber to swing back and forth within the outer chamber about the connection. The inner chamber contains a selected amount of a medium much denser than air and when the ball is in use the ball has eccentric and unpredictable flight characteristics.

Abstract: A toy glider designed for launching with a slingshot like device, the glider having automatically converging wings for creating a swept-back appearance and for reducing air resistance during launch. The wings automatically rotate forward to an extended or glide configuration after launch. Wings are automatically converged by means of a sliding launching hook, which is pulled forward by the slingshot like launcher. When pulled forward, the launching hook slides forward within a longitudinal central aperture between the inboard portion of the wings, simultaneously rotating the inboard portions of the wings forward. This rotates the outlying wings into a swept-back or converged configuration. A rubber band tends to rotate the wing back into an extended or glide configuration, so when the force applied by the rubber band is greater than the forces opposing it, as when the plane slows, the wings are rotated out into an extended or glide configuration.

Abstract: The present invention is a missile-helicopter device which is capable of a projected, nose up ascent and a helicopter nose up descent.
