glass funnel 3d model

Ultra-realistic 3D physics simulation, vertical 9:16 video. A large transparent glass funnel is mounted above a smooth circular metal platform. Dozens of colorful glass marbles are released into the funnel one by one, spinning and bouncing naturally as they travel downward. The marbles collide with each other and create realistic chaotic motion before spreading across the rotating platform. Accurate gravity, rigid-body physics, realistic collisions, detailed glass reflections, cinematic studio lighting, natural shadows, smooth camera movement, satisfying visual motion, clean dark studio background, high-detail 3D CGI, photorealistic render, 4K quality, no people, no text, no watermark.
