The video shows a child's hand holding a red ball and placing it into a wooden toy. The toy has a square base and a vertical structure with four shelves, each painted in a different color: red, blue, green, and yellow. The child places the red ball on the shelf and then picks up a green ball and places it on the next shelf. The child repeats this process with the yellow ball, placing it on the third shelf. The video ends with the child picking up the red ball again.
