Inflatable structures work based on the principle of using pressurized air or gas to inflate and maintain their shape. These structures are designed to be lightweight, portable, and flexible, making them useful in various applications such as architecture, temporary shelters, sports facilities, entertainment, and even in space exploration.

Here's how they typically work:

1 Material: Inflatable structures are usually made from durable materials like PVC, nylon, or other synthetic fabrics that can withstand air pressure. These materials are flexible yet strong enough to contain the air and maintain the structure's shape.

2 Inflation: To set up an inflatable structure, it needs to be inflated. This is usually done using an air pump or blower that forces air into the structure through valves or openings. The air pressure inside the structure increases, causing it to expand and take its intended shape.
