I watched through the Story and Bottle Water. I thought the site and the video were both interesting. The video did a great job of introducing and relaying information in a simple way. The use of the the animations and bullet points complemented the narration of the video. The animation helped convey the ideas in a fun way. If the visuals were actual video showing the same process, it would be a little more to digest and would not get the point across as clearly. I also liked the interactive bar on the site. This allowed to jump around to select parts of the video.
Information graphics are sometimes tough to master but I think the site here does a great job and making simple, understandable visuals to go with a complex topic.
