In the video, a person is seen creating a cardboard box with a face drawn on it. The face is green with white eyes and a wide mouth. The person then attaches a red balloon to the box and uses a black marker to draw eyes on the balloon. The person then places the balloon in front of the box and moves it up and down to make the face on the box appear to be talking. The person repeats this action several times, creating the illusion of the face talking.
