Seen this one before. In fact I saw it today again at the Telus World of Science. It's kind of crappily done there, and it doesn't have the stick, just the six pane window. If you happen to go there with your kids it's on the second floor right across from the cafeteria thing by the washroom. The one from the video is much more convincing though.
