In the video, a person is seen using a piping bag to apply cream to a cake. The cake is placed on a rotating stand, and the person starts by piping a circle of cream around the edge of the cake. They then continue to pipe the cream in a spiral pattern, starting from the center and moving outwards. The person's hands are steady as they pipe the cream, and the cake is evenly coated with a smooth layer of cream. The video is shot in a well-lit room, and the person's movements are precise and controlled.
