Is there a way to "revive" raquetballs?

Question

I have a gratudious amount of old raquetballs, and i was wondering if i could bring them back to life or perhaps make a device that keeps new ones alive for longer. I seem to be constantly buying new raquetballs.

Answer 1

I have a friend that owns a sports store, and I use a kind-of air pump to revive it, and I patch it with similar material. It works, for me.

Answer 2

no im pretty sure that there is no way that i know to revive a tennis ball.
