In the video, a person is seen holding a black gear in their hand. The gear has several teeth and is made of metal. The person is standing in front of a machine that is spinning a metal rod. The machine appears to be a lathe, and the metal rod is being shaped into a cylindrical form. The person then places the gear onto the machine, and the gear begins to rotate along with the metal rod. The person adjusts the gear's position and continues to rotate it along with the rod. The video ends with the gear still spinning on the machine.
