    Balloons filled with air usually hold their size and shape much longer, sometimes for up to a week. However, a rubber balloon eventually loses gas to the outside. The process by which a substance or solute migrates from a region of high concentration, through a barrier or membrane, to a region of lower concentration is called diffusion.

    en.wikipedia.org/wiki/Zero-pressure_balloons

    A zero-pressure balloon (ZP) is a style of aerostatic balloon that is unsealed at its base, creating a mechanism by which lifting gas can vent out the bottom of the balloon when the balloon becomes full, allowing the balloon to float at stable altitudes. During the day the gas heats up in the sun, and at night the gas cools causing them to descend.

    The balloon was constructed of polyethylene plastic measuring only .001 inches (0.025 mm) thick. At 10 million cubic feet (280,000 m 3), the balloon envelope was the largest that had ever been successfully launched, expanding to 300 feet (91 m) in diameter when fully inflated. Beneath the balloon hung a large parachute and then the gondola.
