Lab-demo: hypothesis → cook → result → reusable rule

A 5-beat faceless video outline for “Lab-demo: hypothesis → cook → result → reusable rule” in the Cooking science (no faces) niche, derived from caption timing of 2 reference videos.

Angles

• Pose the physics question first ('how do recipes produce the result?')
• Show ingredients grouped by role (wet / dry / leaveners) on screen
• End with a reusable rule, not just a recipe

Beat-by-beat structure

1. Hook (0:00–0:25): one cake, one question — why does it rise?
2. Hypothesis (0:25–1:00): air pockets + leaveners expand in heat.
3. Demo (1:00–3:00): mix → bake → cross-section shot; vary one variable.
4. Result + rule (3:00–3:45): the reusable rule in one sentence.
5. Recap + next experiment. Original narration only.
