An old-style stovetop pressure cooker on a gas burner in a home kitchen, close side view. First 2 seconds: the small weighted valve on the lid sits still, a faint wisp of steam. Next 2 seconds: as pressure builds the valve begins to rock and spin, jets of white steam shooting out in rhythmic bursts, each burst pushing the plume higher. Final second: the valve spins fast with a steady hissing column of steam. Dark tiled backsplash, warm kitchen light, static locked-off camera. Sound: the rhythmic hiss of the spinning valve, no speech. No text, no letters, no logos
