A tennis ball is a pressurized rubber sphere covered in a fuzzy felt fabric. Most professional balls are a specific shade of bright neon yellow for high visibility. This color helps players and fans track the ball against different court backgrounds. The fuzzy felt is not just for looks; it creates air resistance to control the speed. It also allows players to spin the ball by grabbing the surface with their racket. Inside the rubber shell is pressurized air that provides a consistent bounce. For example, a player opens a fresh can of balls and hears a loud hiss of escaping air. This sound proves the balls are new and will bounce at the correct height. Over time, the felt wears down and the air pressure inside slowly leaks out. This makes the ball feel heavy and prevents it from bouncing properly. Professionals change balls every few games to ensure the highest level of performance. A good ball is essential for the fast-paced nature of modern tennis.
