In the video, we see a person's hand holding a mug. The person uses a sponge to clean the inside of the mug. The mug appears to be made of ceramic and has a greenish-blue color. The sponge is white and seems to be made of a soft material. The person's hand is steady as they clean the mug, and the movements are deliberate and careful. The background is blurred, but it appears to be a kitchen counter.
