In the video, a person is seen holding a small white bottle with a silver cap in their left hand and a knife in their right hand. The person unscrews the cap of the bottle and then proceeds to unscrew the cap of the knife. The person then screws the cap of the knife onto the bottle, effectively attaching the knife to the bottle. The person then unscrews the cap of the bottle and places it back onto the knife, completing the attachment. The video is shot against a dark background, and the person's hands are visible throughout the video.
