When the can is opened and the balls are put into play more air starts to push on the inside of the balls. As the balls get older small amounts of air start to seep out which minimises inside pressure. This reduces the amount of air that pushes on the inside of the ball when it hits the ground, thus reducing bounce.Throughout history, fridges have been deployed at the side of courts to maintain the consistency of bounce in every ball while they're waiting to be used. The 53,000 balls used at the tournament will be kept at 20 degrees until it's their time to shine.

You might be surprised to know that a sealed or unopened can of pressurised tennis balls won't last forever. In fact, an unopened can of tennis balls will usually last around 2 years unopened. That's because the pressure in a can of tennis balls will slowly leak out over time through micro leaks in the packaging.Tennis balls will wear out (some much more quickly than others), leaving them feeling heavy and 'dead'. They lose their responsiveness, go flat, do not bounce as high and go dull in colour. These worn down tennis balls tend to make their way to the coach's basket, or even worse become a ball only fit for a dog!around 2 years

Why are tennis balls no longer white
Historically, balls were either black or white in colour, depending on the background colour of the courts. In 1972 the ITF introduced yellow tennis balls into the rules of tennis, as research had shown these balls to be more visible to television viewers.
Tennis balls will go bad after about 2 weeks or 3-4 playing sessions. Unopened tennis balls are kept in a pressurized tube to help them retain bounciness and firmness, but even those will expire after two years (due to very tiny leaks).

The aims of tennis
Each player has a maximum of one bounce after the ball has been hit by their opponent to return the ball over the net and within the boundaries of the court. If they fail to do this, then the opponent wins the point.Hold an old tennis ball at the same height as a new one and compare how high both of them bounce. If the new one bounces quite a bit higher, the old one should be retired. You can also squeeze an old ball and see how squishy it is. A good ball should not give very much in your hand.The Short Answer:
Playing at a recreational level, a can of pressurised tennis balls will last anywhere between 1-4 weeks of light to moderate play. If used for competitive tennis, a pressurised set of tennis balls might last as little as 1-3 hours. Pressureless tennis balls can last 1 year and maybe even longer.Pressureless balls are the best tennis balls for a ball machine since they last longer. Most high level or professional players do not use pressureless balls. They are mostly for amateur play. You can usually buy pressureless tennis balls in high quantities for practicing.
