Hello how may I help you? Hello, I need info on a world record, can you help? Sure, what would you like to know? Can you tell me where the worlds largest indoor waterfall is located? The worlds largest waterfall is in the Oceanic Forest. Is that indoors? Yes, it is indoors, my apologies. Thank you. Can you tell me where the tallest waterfall in nature is? Of course! The world's largest waterfall that isn't indoors is Niagra Falls in Canada. Wow, very interesting. That is all I needed to know, thank you very much! Anytime!
