In the video, a person is seen holding a black marker and drawing on a whiteboard. The person starts by drawing a vertical line, then adds a curved line on the right side of the vertical line, and finally draws a curved line on the left side of the vertical line. The person then draws a curved line that connects the two curved lines, creating a shape that resembles a fish. The person's hand is steady, and the marker leaves a thick, dark line on the whiteboard. The video is shot from a close-up angle, focusing on the person's hand and the whiteboard.
