AI Video Prompt: Iridescent Sand Heart Reveal

A photorealistic cinematic macro vertical video (9:16), completely static camera. An extreme close-up of wet, packed beige beach sand under natural sunlight. A human hand with fair skin enters from the top right, holding a translucent blue plastic spoon with a curled handle. The hand gently presses the spoon into the wet sand, scooping out a small depression. Then, the hand uses the spoon to carefully draw a heart shape in the sand, dragging the spoon to push the wet sand outward and form a raised border. Once the heart outline is complete, the hand dips the spoon into the center and stirs in a circular motion. Magically, a swirling, viscous, iridescent liquid metal (mixing vibrant pink, purple, cyan, silver, and white pearlescent colors) rises from the center and smoothly fills the heart shape, staying perfectly contained within the sand border. The hand then lifts the spoon straight up and out of the frame. The video ends with a mesmerizing, glossy, swirling iridescent liquid heart resting in the wet sand. Shallow depth of field, sharp focus on the sand and liquid, highly detailed textures, satisfying and magical aesthetic, 8k resolution.
