In the video, a person is holding a spark plug in their hand. The spark plug has a metal body with a threaded end and a ceramic insulator at the top. The person rotates the spark plug to show different angles, including the threaded end and the insulator. The spark plug appears to be used, with some signs of wear and discoloration. The person's hand is visible in the frame, and they are wearing a ring on their finger. The background is blurred, but it seems to be an indoor setting with a white wall and a door.
