An inflatable is an object that can be inflated, usually with air, but hydrogen, helium and nitrogen are also used. The advantage of an inflatable is that it can be stored in a small space when not inflated, since inflatables depend on the presence of a gas to maintain their size and shape. Air is a name for the mixture of gases present in the Earths atmosphere. ...

Smaller-scale inflatables (such as pool toys) generally consist of one or more "air chambers", which are hollow enclosures bound by a soft and flexible airtight material (such as vinyl), which a gas can enter into or leave from through valves (usually one on each air chamber). The design dependence upon an enclosed pocket of gas leads to a need for a very durable surface material and/or ease of repair of tears and holes on the material, since a puncture or tear will result in the escape of the gas inside (a leak) and the deflation of the inflatable, which depends on the gas's pressure to hold its form. Detectable leaks can be caused by holes (from punctures or tears) on the material, the separating of seams, the separating of valve parts, or an improperly shut or improperly closing valves. Even if an inflatable possesses no macroscopic leaks, the gas inside will usually diffuse out of the inflatable, until equilibrium is reached with the pressure outside the inflatable. Material is the substance or matter from which something is or can be made, or also items needed for doing or creating something. ...
A vinyl is an organic molecule containing a vinyl group: H R / C = C / H H where R represents a functional group such as a hydrocarbon or halogen. ...
A valve is a mechanical device that regulates the flow of fluids (either gases, fluidised solids, slurries or liquids) by opening, closing, or partially obstructing various passageways. ...
Pressure is the application of force to a surface, and the concentration of that force in a given area. ...
Diffusion is the spontaneous spreading of something such as particles, heat, or momentum. ...

Most inflatables are made of material that does not stretch upon inflation; a notable exception of this is the balloon, whose rubber stretches greatly when inflated. The airship is usually inflated with helium as it is lighter than air and doesn't burn unlike hydrogen airships such as the Hindenburg. The expression lighter than air refers to objects, usually aircraft, that are buoyant in air because they have an average density that is less than that of air (usually because they contain gases that have a density that is lower than that of air). ...
Combustion or burning is an exothermic reaction between a substance (the fuel) and a gas (the oxidizer), usually O2, to release heat. ...
