The video shows a man wearing a black hat and a black t-shirt with a geometric design. He is standing in front of a window and holding a clear glass of water. The man is talking to the camera, and he appears to be demonstrating how to hold the glass of water. He holds the glass with both hands and then with one hand, and he shows how to hold it in different positions. The man's facial expressions and body language suggest that he is explaining the process in detail. The video is shot in a well-lit room, and the man is the only person visible in the frame.
