A ping pong ball is a lightweight, small-sized spherical object typically used in the game of table tennis, also known as ping pong. It is composed of a hollow plastic material, usually celluloid or sometimes polyethylene, allowing it to have a low weight while remaining durable. With a standard diameter of 40 millimeters and weighing approximately 2.7 grams, the ping pong ball is specifically designed to meet the requirements of table tennis gameplay.
The surface of the ball is usually white or orange, providing good visibility against the table surface and contrasting with the players' equipment. It often features a matte finish to reduce glare and improve the visibility under different lighting conditions. Ping pong balls are designed to be resilient and have a consistent bounce, ensuring fair gameplay and precise ball control.
These balls are specifically engineered to produce a moderate amount of spin and speed when struck by the table tennis racket during gameplay. Their lightweight nature allows for swift movements, quick changes in trajectory, and enhanced player reaction speeds. Due to their small size and light composition, ping pong balls can achieve high velocities with relatively low force.
In addition to competitive play, ping pong balls are frequently used for recreational purposes, training exercises, and even for various games outside of table tennis. Despite being primarily associated with table tennis, ping pong balls are versatile objects that find applications beyond the sport, serving as an essential component in various entertainment activities and scientific experiments.
