Ain't rocket science, if you add more nitrogen to air, you deplete the oxygen partial pressure, (percentage in laymans terms), reduce it too much you will loose consciousness, reduce it to a low level and you will suffer irreversible brain damage and possibly death.

So why fk with it.

P.S. I am aiming my comments at the irriots who added it to a swimming pool.

To me, it would not be obvious in advance that the nitrogen would hang around on the surface of the pool rather than harmlessly dissipating into the atmosphere.

In fact I'd be more concerned with the risk of spilling the stuff on skin, eyeballs etc.

I hope Jaegermeister have a meaty legal budget.

Look what happens when they pour it into a drink - the cold gas (which you can see because it condenses water vapour in the air)sits in the glass and flows out over the sides and downwards. Cold gas is denser than warm gas. When they poured it into a swimming pool and created a layer of fog sitting on top of the water, it should have been pretty obvious where the liquid nitrogen was hanging around, because they could see it!

But...but...what you're seeing is the water vapour, not the nitrogen. I would expect oxygen to diffuse into that layer pretty quickly.

argon would be the best bet for replacing nitrogen I think.
Can't remember the percentage, but argon is quite narcotic.

IIRC it's the ideal anaesthetic agent. You'd be better of with xenon.

It's not that bad as a burn hazard on skin - you tend to get an insulating layer from the stuff that boils off. Anyone who works with it, or buys it, should have had plenty of dire warnings about the asphyxiation hazard though. They're going to have a rough time in court,

Actually

Liquid cryogenic temperature gases id very much a big part of rocket science
