Abstract
A ball for use in street hockey comprised of a hollow sphere and a freely moving liquid contained within a volume of the sphere. The sphere having a smooth, unobstructed and spherical inner surface and being constructed of a bounce resistant material. The liquid, most preferably non-toxic liquid antifreeze, occupying less than one-half of the volume of the sphere and serving to dampen energy and to lower the center of gravity of the ball below its geometric center.
