In this audio recording, the primary focus is on the unique sound produced when a plastic bottle pops. The recording begins with the subtle crinkling noise of the plastic as it is handled. Then, there is a sudden, sharp popping sound that echoes briefly. It is the sound of a plastic bottle being squeezed until the air pressure inside forces the plastic to expand rapidly, creating a pop. The sound is both distinct and somewhat startling, an unexpected break in the silence. The echo of the pop slowly fades, leaving behind the quiet rustling of the plastic bottle as it is released and returns to its original shape.
