In the video, a person is seen decorating a cupcake with white icing. The person is using a piping bag to apply the icing in a circular motion, starting from the center and moving outwards. The cupcake appears to have a red base, and the icing is being applied in a way that creates a swirl pattern on top. The person's hands are steady, and they seem to be experienced in this task. The background is blurred, but it appears to be a kitchen setting.
