A method and article of manufacture are disclosed for manufacturing a robust tethered ball. The method includes steps of: (a) providing an elastic tether; (b) cutting the tether to a desired length so that the tether has an end portion that extends from an inner portion of the tether to an end of the tether; (c) folding the end portion of the tether straight back upon the inner portion of the tether so that the end portion of the tether including the end of the tether lies parallel to the inner portion of the tether; (d) securing the end portion of the tether to the inner portion; (e) coating the end portion of the tether including the end of the tether and the inner portion of the tether with an adhesive to provide adhesion between the tether and a liquid polymer; and (f) forming a solid ball on the end portion of the tether from the liquid polymer that completely includes the end portion of the tether, the end of the tether, and the inner portion of the tether.
