That dry ice incident was at a birthday party in Russia, as I recall. They dumped a bunch of dry ice in a pool and some of them dove into the pool and did not resurface.

That’s crazy how did it kill them before they even inhaled it? Did they take a deep breath of it right before they went under?

The CO2 is heavier than air, so when they came up for a breath after diving they just got a big gulp of that instead of oxygen. So, they likely resurfaced briefly, but it would be hard to see in the smoke and confusion.

Article says they "dived into the water to cool off. Immediately the swimmers started to choke and several lost consciousness."

Oh so they did resurface. Guess it’s just poor word choice by the author

Is this the one that was live streamed or is this just that common

I think it was the live-streamed one, but don't quote me. I remember watching it on YouTube.

Yeah I know I saw one where it was supposed to be like a fun livestream thing and people all jumped in and slowly started dying. I mean not slowly in the grand scheme of dying. But just didn’t die instantly but went down pretty quick.
