The video shows a person decorating a cake with blue icing. The cake is round and has a white base. The person is using a knife to spread the icing evenly on the cake. They are also using a piping bag to create a design on the side of the cake. The design consists of blue icing stripes that are evenly spaced and neatly applied. The person's hands are visible as they work on the cake, but their face is not shown. The background is a solid pink color, which contrasts with the white and blue of the cake.
