history: hey do you know much about Niagara Falls? I know that it's the name applied to three waterfalls that are on the border between the US and Canada. Oh thats cool, what state/area is it in? I couldn't really say. There is a city that is within the Buffalo-Niagara Falls Metro Statistical Area, though. oh wow didnt know it was i/next to new york, how long has it been an attraction? I'm not sure. It sits between Ontario and New York. how many people visit it? is it really popular?
knowledge: During peak daytime tourist hours, more than six million cubic feet (168,000 m) of water goes over the crest of the falls every minute.
