In the video, a young boy is seen sitting at a table with three cups of colored water in front of him. He dips a paper towel into each cup, one by one, and then holds up the paper towel to show the color of the water. The first cup contains yellow water, the second cup contains blue water, and the third cup contains clear water. The boy then dips the paper towel into the clear water and shows it to the camera. He repeats this process with the other two cups, dipping the paper towel into the blue and yellow water and then holding it up to the camera. The video ends with the boy giving a thumbs up to the camera.
