Hello how may I help you? Is this a repository of World Records? Checking. You don't know? Yes. there are a couple of sites that provide information on world records. I thought this was one of them. Am I mistaken? I merely provide information on world records from third party websites. Not very well, so far. Anyway, where is the tallest indoor waterfall located? The tallest indoor waterfall is currently located in Singapore. Where is the tallest waterfall? The tallest water fall is in Rio Caroni Thank you, bot.
