In the video, we see a close-up of a person's hand holding a piping bag filled with yellow icing. The person is using the piping bag to apply the icing onto a row of yellow pastries that are lined up on a black tray. The pastries appear to be of a cylindrical shape, and the icing is being applied in a smooth, consistent manner. The person's hand moves steadily along the row of pastries, ensuring that each one is evenly coated with icing. The background is blurred, but it appears to be a kitchen setting.
