Have you seen this science experiment?

I'm not much of one to look for videos on the internet, so I am usually the last person to see them. I saw this video in a training class at work. Science is so cool.

Sorry, no explosions in that video. The training class I had seen that in was on safety, but don't really know why they showed that video. They did show some other pretty good videos of people doing stupid stuff and falling.

To show how gases sink and if you pass out in a environment like that then you will potentially die because you will be laying on the ground breathing that stuff.

That's my guess
