In the video, a person is seen decorating a gingerbread man cookie with icing. The cookie is already partially decorated with white and blue icing. The person uses a piping bag to apply the icing in a zigzag pattern, starting from the top of the cookie and moving downwards. The icing is applied carefully and with precision, ensuring that the zigzag pattern is even and consistent. The person's hand is steady, and the icing is applied in a smooth, controlled manner. The gingerbread man cookie is placed on a flat surface, and the background is not visible in the video. The focus is solely on the decorating process, and the viewer can see the transformation of the cookie as it becomes more colorful and festive with each added zigzag of icing.
