Sonrisa triste de la lluvia

A puddle of soapy water on a wet concrete surface forms a stable, smiling face shape, with two dark circular bubbles for eyes and a larger, curved bubble forming a mouth, all contained within a triangular patch of white foam; the foam face remains largely unchanged throughout the loop, with only minor shifts in the surrounding water and a small white object floating nearby, set against a backdrop of a beige wall and a vertical pipe.
