摘要: A recreational ball has a self-supporting flexible wall surrounding an internal space. One side of the wall has first features that extend into or at least face the internal space, and the other side of the wall has second features at the ball exterior. A hole in the flexible wall allows the first features to pass to the ball exterior as the ball is turned inside-out.
