Abstract
A ball pit ball for use in ball pits or seas of balls with desiccant for absorbing moisture from a surface of the ball pit ball and from neighboring surfaces. The ball pit ball has a generally spherical hollow outer shell defining an open inner volume with a volume of desiccant material, such as calcium chloride, in the open inner volume of the outer shell. The desiccant material can be liquid, such as calcium chloride brine, or solid and can comprise one or more desiccant materials in combination. A volume of chlorine may be further disposed in the open inner volume of the ball pit ball, possibly with a proportion of two parts chlorine to one part calcium chloride.
