The video shows a person wearing a white lab coat sitting at a table. In front of them is a tall glass filled with a dark liquid on top and a white liquid on the bottom. The person is holding a spoon and stirring the two liquids together. As they stir, the dark liquid begins to mix with the white liquid, creating a swirling pattern. The person continues to stir, and the liquids begin to blend more thoroughly, creating a marbled effect. The video ends with the two liquids fully mixed, creating a uniform color throughout the glass.
