In the video, a person is seen using a piping bag to apply icing onto a tray of pastries. The icing is yellow in color and is being applied in a circular motion to the top of each pastry. The pastries are arranged in a neat row on the tray, and the icing is being applied with precision and care. The person's hand is steady as they move the piping bag back and forth, ensuring that each pastry is evenly coated. The background is blurred, but it appears to be a kitchen setting.
