The performance of a tennis ball depends on its internal pressure. This provides the springiness and the bounce. When tennis balls are packed they are packed in a pressure pack. This limits the leaking of internal pressure. Once a can is opened, the balls are surrounded by the lower ambient atmospheric pressure. Over time, the balls lose much of their action. Old tennis balls work better as toys for Labrador Retrievers.Dear all,

I would appreciate any comments.
