A macro 3D animation showing gas bubbles forming and expanding quickly inside a creamy cake batter. The batter has a light beige color, thick and smooth texture — not watery, not oily. Bubbles appear rapidly and evenly throughout the mixture, staying round and rising softly. The animation feels clean, bright, and scientific, with soft white lighting and gentle camera movement. The atmosphere conveys a sense of freshness and precision, like a perfect chemical reaction in pastry. No text, no labels, no sound — only visuals.
