Volcano enables synchronized group watching of YouTube videos by redirecting modified URLs through a co-viewing service. Users change "youtube.com" to "you---tube.com" in any video link, then share the resulting URL with others to watch together in real-time. The streams are private and accessible only to people who receive the shared link, making it useful for friends or groups who want to watch videos simultaneously while seeing each other's presence online.
