The video shows a person's hand pushing over a domino that is set up in the shape of a rainbow. The dominoes are arranged in a semi-circular pattern on a tiled floor. The dominoes are of different colors, including red, yellow, green, and blue. As the domino falls, it causes a chain reaction where each domino falls onto the next, creating a continuous motion. The person's hand is visible in the frame, and they are wearing a black shirt. The video is shot from a top-down perspective, and the camera remains stationary throughout the video.
