In the video, a person is holding a metal object in their hand. The object has a circular shape with a series of teeth around its edge. The person is also holding a blue plastic cover, which they are trying to fit onto the metal object. The cover has a curved shape and a hole in the center. The person is carefully aligning the cover with the teeth of the metal object and appears to be attempting to fit it onto the object. The background of the video is blurred, but it seems to be an outdoor setting.
