Abstract: An egg-shaped elastomeric ball having a unique combination of texture, size, weight and composition features such that it can be thrown and bounced in a controllable manner, after the user develops a certain level of skill. Methods of manufacture and use in exercise, entertainment and sports are also described. The eggball has a major to minor axis ration on the order of 1.3 to 1.6, and more preferably in the range of 1.4 to 1.5, a major axis dimension in the range of about 23/4 to 31/4", a mass on the order of from 60 to 120 grams, and preferably in the range of from 80 to 100 grams, and an exterior surface that while smooth, is textured and can be characterized as sanded or frosted. The durometer is between 30 and 40 and preferably from about 33 to 37. In the preferred embodiment, the surface texture is sanded, so that the exterior of a transparent composition has a translucent frosted look.
