The video shows a close-up of a person's hand holding a blue piping bag and squeezing out blue frosting into a cupcake mold. The mold already contains a dollop of white frosting and a dollop of red frosting. The blue frosting is being added to the center of the mold, creating a swirling pattern. The person's hand is steady, and the frosting is applied in a controlled manner. The blue frosting contrasts with the white and red frosting, creating a visually appealing effect.
