The camera zooms in on an empty, transparent bottle resting on a sleek reflective surface. Suddenly, from above, a clear fluid begins to pour in slow motion—captured with realistic fluid simulation. The liquid splashes and swirls as it hits the base, creating air bubbles and soft ripples. As the bottle fills, caustic light patterns dance on the inner walls, emphasizing clarity and purity. Tiny droplets cling to the inside of the bottle, enhancing realism. Once filled, the liquid settles smoothly, and a subtle glow or brand mark appears, completing the clean and refreshing visual.
