In the video, a person is holding a ruler in their hand. The ruler is made of wood and has black markings on it. The person is using the ruler to measure the length of a yellow rubber band. The rubber band is stretched out and appears to be about 10 inches long. The person's hand is steady as they hold the ruler against the rubber band, and they carefully measure the length. The background is a plain white surface, and there are no other objects in the frame.
