Orange felt balls bounce higher and move faster than the Red felt or foam balls but lower and slower than the Green ball. ADVERTISEMENT They are a step toward the traditional yellow tennis ball while still remaining fun and manageable for players learning the game.

Do tennis balls deflate?

They slowly lose their pressure as the gas inside the ball escapes to the outside which, translates to losing their bounce over time. And remember, much a like an opened soda can that goes flat, an opened tennis can will lose their bounce as well, even if they are unused.

What is a dead tennis ball?

A dead tennis ball signifies a ball that is old and has lost its bounce. In other words, it becomes flat and bounces much less than a ball fresh from the can. Depending on its use a new ball can become dull within just one session of constant hitting for a few hours.

Do tennis balls break?

You'll be surprised how many tennis balls actually break during fast serve contests and warmups in higher level tournies. I've seen 3 out of 21 break within 10 minutes in hot weather A/Open practices.

Why is second serve slower?

The first serve is hit harder, usually closer to the lines, because the server is trying to gain an advantage while knowing they can fall back on the second. The second must go in or the server loses the point, so is almost always hit slower to reduce that risk.
