ABSTRACT:
A football or other projectile is stabilized in flight by weighted material that responds to spinning of the football about its major axis by moving radially outward to become evenly distributed about that axis. In a preferred embodiment, two annular tubes, concentrically disposed about the major axis, encircle the ball at opposite sides of a plane containing the minor axis of the ball. The weighted material, in the form of beads, liquid, etc., is contained within the tubes and is flung radially outward as the ball spins.
