The video shows a person using a piping bag to decorate a cake. The cake is round and has a smooth, light blue icing. The person is using a piping bag with a yellow nozzle to create white icing roses on the top of the cake. The roses are intricately designed with multiple layers of petals. The person's hand is visible in the frame, holding the piping bag and moving it in a circular motion to create the roses. The background is a plain white surface, which contrasts with the blue icing and white roses, making the decorations stand out.
