The video begins with a person drawing a curved line on a white surface. As the video progresses, the person continues to draw, eventually creating the outline of an airplane. The person then adds details to the airplane, such as the wings and tail, and writes the word "airplane" next to it. After completing the airplane drawing, the person writes the words "lift" and "weight" on either side of the airplane, with arrows pointing upwards and downwards respectively. The video ends with the person writing the word "airplane" again, this time with the arrows pointing upwards and downwards.
