In the video, a person is holding a tool in their hand. The tool has a larger diameter on one side and a smaller diameter on the other side. The person is using their thumb to point to the larger diameter and the index finger to point to the smaller diameter. The video is shot in close-up, focusing on the tool and the person's hand. The background is blurred, but it appears to be a workshop or garage setting. The person's hand is steady, and they seem to be explaining the difference between the two diameters. There is no audio, so it is unclear what the person is saying.
