Reinforced rubber

Rubber is a type of material that can stretch and is very bouncy. Reinforced rubber means that the rubber is made even stronger by adding more materials to it. Think of it like adding extra muscles to a person to make them stronger. The added materials can be things like metal wires, fiberglass or nylon. This type of rubber is used in things like tires, belts, and hoses because it can handle heavy weight and pressure without breaking or wearing out easily. Just like how a strong bridge can hold a lot of cars, reinforced rubber can hold a lot of weight and last a long time.
