English Prompt

Cinematic video, 16:9, 15: a glass marble runs a physically believable Rube Goldberg machine in a whimsical wood-and-brass inventor's workshop. Warm morning light, dust rays, steampunk detail, amber/teal palette, shallow depth of field.

Open macro on the marble atop a wooden track; a tiny mechanical arm releases it. It rolls through a chain of mechanisms — copper helix, dominoes tipping a spoon that launches a ball bearing into a pulley bucket, tuned metal plates, a toy wagon, a wind-up bird pulling a cord that opens a trapdoor — each action clearly triggering the next, with steam bursts, gears, and bells along the way.

Finale: the marble hits a switch, the workshop lights up, and a mechanical hand pours a perfect cup of coffee. The marble settles beside it as a sign flips to "TASK COMPLETE."

Camera: continuous tracking shot, macro to wide, slow motion on key drops. Audio: clicks, creaks, bells; orchestral flourish only at the finale.
