Basketball

A basketball is a spherical inflated ball used in the game of basketball. Basketballs typically range in size from very small promotional items only a few inches in diameter to extra large balls nearly a foot in diameter used in training exercises to increase the skill of players. ... The surface of the ball is nearly always divided by "ribs" that are recessed below the surface of the ball in a variety of configurations and are generally a contrasting color. A brown surface with black ribs and a possible logo is the traditional color scheme of basketballs but they are sold in various colors. Balls are generally designated for indoor (generally made of leather or absorbent composites), or all-surface use (generally made of rubber or durable composites, also known as Indoor/Outdoor balls).
