The audio starts with the distant, soothing sound of a gentle tap running, filling an unseen container with water. This gradually transitions into a low, persistent hum, signifying the initiation of the heating process. The hum steadily increases in intensity, mirroring the rising temperature of the water. The first bubbles, tiny and quick, start to form at the bottom of the liquid. They rise slowly, bursting as they reach the surface, creating a soft, popping soundscape. As the heat continues to escalate, the bubbles grow larger and more frequent, their pops becoming a constant, rapid rhythm. The audio concludes with the crescendo of a rolling boil, where the liquid is transformed into a turbulent, boiling mass, the bubbles bursting rapidly, creating a continuous, roaring sound.
