In the video, a person is seen assembling a contraption made of a blue plastic cup, a green piece of paper, and a rubber band. The person places the green paper under the cup and attaches the rubber band to the cup and the paper. They then proceed to place a marble on the paper and pull the rubber band back, causing the marble to be launched into the air. The video captures the person's hands and the contraption, but not their face or the surrounding environment. The focus is on the action of the marble being launched.
