The video shows a close-up of a person's hand using a paintbrush to mix a pink liquid in a container. The paintbrush is dipped into the liquid, and the person swirls it around to create a marble effect. The liquid appears to be thick and glossy, and the brush strokes create circular patterns on the surface. The person's hand is steady, and the brush moves smoothly through the liquid. The color of the liquid is a vibrant pink, and the light reflects off the surface, giving it a shiny appearance.
