In the video, a person is holding a small blue boat in their hand. The boat appears to be made of plastic and has a small metal spring attached to it. The person is using their thumb to push the spring up and down, causing the boat to rock back and forth. The boat is small enough to fit comfortably in the person's hand, and the spring is positioned in the center of the boat. The person's thumb is visible in the video, and they are using it to control the movement of the boat. The background is not visible in the video, and the focus is solely on the boat and the person's hand.
