Custom Sponge Rubber Core Sport Ball

I'm in need of a custom-designed ball that’s the standard size of a baseball similar to baseball. The ball should have a sponge rubber core with a soft foam exterior, making it suitable and safe if players are impacted or contacted by the ball but durable enough to be hit by a baseball bat and solid and aeronautical enough to be thrown by a baseball player. The design includes a muffled bell or chime in the center which upon contact should produce a sound that is distinct and clear, but muffled enough not to be overly loud.

Ideal skills and experience for this project include:
- Product design, particularly for sports equipment
- Understanding of sound engineering to ensure the ball produces the correct type of sound
- Proficiency in material selection to balance durability and softness
- Experience in creating prototypes for testing and refinement.
