You can say that again. Growing up in Florida, I’ve been in a lot of swimming pools and water parks, and I have never seen anything like what is shown in the video attached to this article. That opening is huge. user224’s link says the pipe is 30cm (almost a foot) in diameter. Even in giant public pools I’ve been in, I can’t recall seeing an opening or fixture that size. That, coupled with a lack of any cover on it, seems so obviously dangerous. God, what an awful way to go.
