Air expulsion from a bag

A sharp, sudden sound fills the air, echoing the release of trapped pressure. It's the unmistakable sound of air being expelled from a bag. The noise is swift and sudden, akin to the swift "woosh" of a gust of wind or the exhale of a deep breath. The bag, once plump and full, now collapses, its purpose fulfilled. The sound resonates briefly before fading away, leaving behind the quiet rustling of the now empty bag. The release of the air signifies the end of its containment, a final gusty sigh of liberation.
