Abstract
Abstract A body has a substantially flat and very smooth support surface having a plurality of holes therein which intersect the support surface to form sharp edges around the holes. Connectors are provided on the sides of the body for connecting similar bodies to one another. A plurality of projections extend outwardly from the surface to enhance the glide properties of inline hockey pucks. The projections have a base dimension at the support surface in the range of about 0.5 mm to about 1.5 mm and extend outwardly from the surface a distance in the range of about 0.1 mm to about 0.6 mm. The projections are spaced from one another a distance in the range of about 3 mm to about 10 mm, and the density of projections per square centimeter of the support surface is in the range of about 1 to about 9.
