Seedance 2.5 Prompt - Professeur de physique 3D aux billes magnétiques

Create an ultra-high-quality 10-second 8K educational short in a polished semi-realistic 3D cartoon style. Feature energetic male physics teacher, late 30s, messy dark hair, orange sweater, expressive eyebrows teaching how magnetic forces act without touching in stylish physics laboratory with metal demonstration table, using magnet pulls iron beads into patterns through transparent acrylic as the central physical demonstration. The demonstration must look intuitive enough that a viewer can understand the basic idea visually before the teacher finishes speaking. Begin with a strong 0–2 second hook: the ordinary teaching object unexpectedly performs an impossible but scientifically meaningful action. The teacher notices it and immediately guides the viewer's attention toward the phenomenon. Structure the entire video as five connected 2-second beats: 0–2s SURPRISE — the object behaves unexpectedly; 2–4s QUESTION — the teacher introduces the educational question; 4–6s EXPLANATION — the phenomenon visually demonstrates the answer; 6–8s AMPLIFICATION — the demonstration becomes clearer and more spectacular while remaining scientifically coherent; 8–10s PAYOFF — everything resolves into one elegant visual representation that reinforces the lesson. Deliver concise spoken narration using enthusiastic male voice with playful scientific curiosity. Keep each sentence short, conversational, accurate and easy to understand. The teacher should speak naturally rather than sounding like a textbook. Use carefully synchronized ASMR sound design: object contact, subtle hand movement, paper, glass, liquid, air, mechanical movement or other sounds appropriate to the demonstration. Add original background music that begins quietly, builds during the discovery and resolves with a satisfying final musical accent. Use smooth cinematic tracking, macro close-ups, controlled rack focus, gentle camera arcs and a final reveal. Keep the teacher visually dominant while allowing the demonstration to temporarily become the focal point during the explanation. Use attractive educational lighting, realistic material behavior, soft atmospheric depth and polished semi-realistic cartoon rendering.
