In this video, we see a close-up of a bathtub filled with bubbles. A person's hand is holding a white cup, and they are pouring a brown liquid into the bubbles. The liquid is being poured in a circular motion, creating a swirl in the water. The bubbles are white and foamy, and they contrast with the brown color of the liquid. The bathtub appears to be made of white porcelain, and the lighting in the room is dim.
