The audio titled "Pump" begins with a steady rhythm of a unitary electromechanical machine, or UEM, in operation. The pulsating sounds of the UEM, which is a type of pump or "pompa" in Spanish, fill the background. The rhythmic hums and whirrs create a sense of anticipation. Suddenly, without warning, there's a loud sound of an explosion, or "explotando" in Spanish. The once rhythmic hums and whirrs of the UEM are replaced by the cacophonous noise of metal and machine parts clattering onto the ground. The explosion echoes for a few seconds, creating a shuddering feeling of shock before the audio ends, leaving a silence that is stark in contrast to the sudden eruption.
