this is really confusing, I don't have a clue what the tennis ball is all about. How do you attach a pump? Maybe a diagram would help

This seems to be a physics assignment. This is the fourth water rocket I've seen here that carries a tennis ball. According to the first one I read, the rocket's mission was to keep the ball in the air for 30 seconds. It must have also been in the assignment to write an instructable about it.
