The video shows a close-up of a person's hand as they sprinkle rainbow sprinkles onto a cake. The cake has a white frosting on top and the sprinkles are being added to the edge of the cake. The person's hand is steady as they carefully place each sprinkle onto the cake. The sprinkles are small, cylindrical, and come in a variety of colors including red, yellow, green, blue, and purple. The cake itself is not fully visible, but it appears to be a chocolate cake based on the color of the frosting.
