AI Video Prompt: Golden Ball Marble Machine

Create a 10-second ultra-realistic vertical 9:16 cinematic 3D animation of a futuristic marble-run machine. A polished golden metallic sphere begins suspended above transparent circular rings, then drops into a transparent spiral tube system. The sphere travels smoothly through curved glass pathways and white marble tracks using realistic gravity physics. The machine includes elegant green mechanical supports and premium futuristic design elements. Additional golden spheres interact with the mechanism as platforms and levers activate. Use realistic metallic reflections, glass transparency, marble textures, soft studio lighting, and smooth cinematic camera tracking. One continuous satisfying physics animation, no characters, no text, no watermark.
