What's Inside a Baseball: Is It Hollow or Is It Filled?
A baseball is not hollow but rather a tightly wound sphere of cork and rubber. The cork center is wrapped in two layers of rubber thread, which are then covered in a horsehide leather casing. The tightly wound layers give the baseball its signature hardness and bounce.
The cork center is typically made from the bark of a cork oak tree, which is native to the Mediterranean region. The cork is lightweight and buoyant, making it an ideal material for the core of a baseball.
The rubber thread used to wrap the cork center is made from a combination of natural and synthetic rubber. The rubber helps to cushion the impact of the ball and provides it with its bounce.
The horsehide leather casing is the outer layer of the baseball. It is made from the skin of a horse and is typically tanned and treated to make it durable and resistant to water.
