In the video, a person's hand is seen holding a black object and rubbing it against a pink surface. The black object appears to be a small, round, and smooth object, possibly a stone or a piece of plastic. As the person rubs the object against the surface, it leaves behind a trail of small, dark particles that are scattered across the pink surface. The hand moves back and forth, and the particles spread out, creating a contrast between the black particles and the pink background. The video is shot in close-up, focusing on the hand and the surface, and the lighting is bright, highlighting the details of the particles and the texture of the surface.
