In the video, a person is seen drawing a grid on a whiteboard using a blue marker. The grid consists of nine squares, with three rows and three columns. The person starts by drawing the top and left sides of the grid, then proceeds to draw the remaining sides. The grid is drawn in a straight line, and the person takes their time to ensure that the lines are even and precise. The video is shot from a top-down perspective, and the person's hands are visible as they draw the grid.
