Golf ball with configurable materials and method of post production modification

A golf ball comprising:

• a core,
• a mantle layer surrounding the core;
• a cover layer surrounding the mantle layer;
• wherein at least one of the core and the mantle layer comprises a member selected from the group consisting of nitrogen blowing agents subject to activation with heat;
• magnetic materials entrained within heat labile materials that undergo polymerization upon heating;
• and combinations thereof, wherein the member comprises a magnetic material entrained within a heat labile material that undergoes polymerization upon heating.
