In the video, a person is seen holding a piece of paper with a blue line drawn on it. The person then folds the paper in half, and the blue line is now visible on both sides of the fold. The person then points to the blue line and folds the paper again, this time with the blue line on the outside. The person repeats this process several times, folding the paper and pointing to the blue line each time. The video is shot in a well-lit room with a wooden floor, and the person is wearing a ring on their left hand.
