A lightweight, non-injurious amusement ball designed for use in a restricted area or where it is desirable to prevent injury to the surroundings and participants from impact with the ball. The ball is fabricated from resilient, cellular plastic foam strips of rectangular cross section compressed in a central core and extending radially into an essentially spherical periphery. The periphery is impact absorbent and wind resistant for non-injurious activity and limited flight. A core is used to tie and compress the strips in the central core, providing increased density for stable trajectory.
