In the video, a person is holding a small gear in their hand. The gear is made of metal and has several teeth around the edge. The person then places the gear into a larger gear that is attached to a motor. The larger gear is also made of metal and has teeth that mesh with the smaller gear. The person then rotates the smaller gear, causing the larger gear to rotate as well. The motor is silver and has a cylindrical shape. The person's hand is visible in the frame, and they are wearing a white shirt. The background is a plain white surface.
