Heat flowing the wrong way: a black cast iron frying pan on a gas stove, a steady blue flame burning beneath it, a single ice cube sitting in the centre of the pan, seen close from a high three-quarter angle. First 2 seconds: instead of melting, the ice cube grows larger, its edges sharpening. Next 2 seconds: white frost creeps outward across the hot pan in feathery crystals, spreading from the cube toward the rim. Final second: the whole pan is coated in glittering frost while the flame keeps burning blue below. Warm kitchen light, slightly faded 1990s film colour and grain, macro, static locked-off camera.
