Inflatable devices are objects that can be filled with air or gas to create a larger, functional form. Common examples include air mattresses, beach balls, and life jackets. These devices are often made from flexible materials like plastic or rubber, allowing them to be easily stored and transported when deflated. Inflatable devices serve various purposes, from recreational activities to safety equipment. For instance, inflatable boats are used for water sports, while inflatable slides provide entertainment at events. Their lightweight nature and ease of use make them popular choices for both personal and commercial applications.
