Abstract: A ball comprises a shell portion and a filter portion. The filter portion regulates gaseous material exchange and internal pressure of the ball. The shell portion comprises a non-porous material. Solid material such as sand, salt, flour, glass, or magnetic beads are used as filler material within the shell portion to precisely adjust the weight of the ball, allowing for tailored performance characteristics suitable for various applications.
