The video shows a person using a spatula to spread blue icing on a cake. The cake is white and is placed on a turntable. The person starts by spreading the icing on the top of the cake and then moves to the sides, smoothing out the icing to create an even layer. The person's movements are precise and careful, ensuring that the icing is spread evenly. The blue icing contrasts with the white cake, making the cake look visually appealing. The video ends with the person finishing the icing process, leaving the cake with a smooth and even layer of blue icing.
