//A can will last approx 2 plays// I assume you mean, in a professional tournament. For normal people a can lasts right up until all the balls have been lost over the hedge. |

There's a gadget you can buy that puts your tennis balls in a little high-pressure chamber when you aren't using them. Supposed to renew them like this idea. :) |

How are tennis balls pumped in the first place? |

// How are tennis balls pumped in the first place?//
A pellet is placed between the two halves of a hollow rubber ball, two dog bones of felt are glued to the outside of the ball, and the whole thing is vulcanized in a two-part mold with a bunch of other balls. The heat causes the pellet to decompose into gas.
The best way to maintain the pressure in tennis balls is to put them back in the can and place them in the freezer. They will last forever that way. To use them again, take them out half an hour before game time, and allow them to warm up before taking the lid off (prevents them from getting soggy). |

You can try playing tennis at really high altitudes so the ball's relative pressure will be even higher. Or make a really big airlock... |
