Abstract
A ball includes a core, a cover, and a separator or separating layer. The separating layer may be deformed or actuated to separate at least a portion of the cover from the core. This removal allows for easier recycling of the ball parts. The separating layer may include one of a bladder or a hydrophilic material that expand upon the introduction of a fluid, a shape memory polymer that deforms upon application of a stimulus, or two materials that react chemically to form a gas.
