Rubber balls are spherical objects made from rubber, a flexible and durable material. They are commonly used in various sports and games, such as basketball, tennis, and soccer. Rubber balls can vary in size, color, and texture, making them suitable for different activities and age groups. These balls are designed to bounce when thrown or dropped, thanks to the elasticity of rubber. They are often filled with air to enhance their bounce and can be used for recreational purposes, such as playing catch or in dog toys. Rubber balls are also popular in physical education and fitness activities.
