Wouldn't the nitrogen freeze the liquid in the glass she was supposed to be drinking in the first place?
A layer of nitrogen gas would quickly form above/around and close to whatever liquid nitrogen was left in the drink, this would be at the same temperature as the liquid nitrogen when formed but would heat up a bit before escaping and being replaced by fresh N2 gas. All the way it would offer insulation to the liquid nitrogen, and the drink.

It would seem that there are two applications for it - turning a cocktail into a sorbet, and creating a dry ice style smoke effect by pouring it into the glass. The latter seems to me to create the risk of swallowing it, the former much less so.

I use it every day and I treat it essentially in the same way that I would treat boiling or hot water.
Except, of course, hot or boiling water is also very, very dangerous.
Here's an example

HF is dangerous (see above), carbon monoxide is dangerous , some of the other chemicals I work with are dangerous... Liquid nitrogen is about as hazardous as hot water.

Liquid nitrogen shouldn't be there in the first place. Just because it's not toxic doesn't mean it's not dangerous. Very, very dangerous.

I use it every day and I treat it essentially in the same way that I would treat boiling or hot water. Wear insulating gloves or be careful. try to avoid pouring on you - although actually this is not particularly a problem. The danger comes if you trap the nitrogen between your skin and something else - which allows it to cool down the layer of insulating gas that usually exists between drops of liquid n2 and warmer objects. when this happens you will start to freeze.

It's quite possible to stick your fingers into liquid N2 for a few seconds and not feel any pain or sustain any injury. equally you can pour it over your skin and not come to any harm - it feels very soft (like being brushed with a cloud or something... er).

obviously I wouldn't want to fall into a tank of the stuff. and of course, if you are working with large volumes in enclosed and badly ventilated areas there is a risk of suffocation - but that is easily managed.
correct .... handled correctly it is fine ... no real need to be OTT with safety gear but regs apply.

you can reach into a polystyrene vessel and lift some out in your palm and drop it on floor if you are brisk and don't allow sufficient time for cold burns. the difference between it and hot liquids is as LN2 comes to equilibrium with it surroundings e.g your hand, body etc. it heats up to room temperature and so vapourises so forms N2 gas which acts as barrier layer. as others have said if she swallowed .... that N gaseous layer would have surrounded blob of liquid into her stomach and then all hell breaks loose. even in a couple of cubic cc of liquid there'll be enough LN2 to totally freeze and kill tissue.

If it's being served at a bar, and it's her fifth cocktail (so bit drunk anyway), and it bubbles away looking awesome because of the liquid Nitrogen boiling off, then I can see why it would be drunk. I mean this looks pretty cool:
http://www.youtube.com/watch?v=cOIP6gN_Dxc

And there's lots of clips of semi-solid cocktails made with liquid nitrogen on youtube. My guess is busy club/inexperienced bartender= gut full of nitrogen which either froze or exploded through her stomach.
First comment: "You want to be careful. You'll have someone's stomach out with that.". Oooof.

And I agree with most that the girl really isn't to blame here. We all know how alchohol and peer pressure work on a night out at that age, and I'm quite sure that if someone had bought me such a thing on my 18th, I'd have drunk it. Now maybe not, but that's experience for ya. There but for the grace of god, and all that...

As per my posts earlier today at 15:21 and 15:44 which must be invisible now, some sympathy is due - but not a great deal.

Yes the bar and its staff must look to themselves very closely.

Old enough to vote, to hold down a job and a flat, marry, have children, and be responsible for those children. Cool.

Smiler.

What a horrendous thing to happen.

Although the young girl is getting some flack on here regarding stupidity, guess what, drunk people do stupid things.

I watched the video posted earlier showing one of these things getting made & it's not inconceivable to imagine someone shouting over "hey we bought you a cocktail" before the person swoops in for a good mouthful before the bar staff can stop them.

Quite simply, it's astounding that bars can put anything so completely dangerous within reach of inebriated customers. Sadly an accident that was simply waiting o happen.

According to the Daily Wail she was bought 2 of these cocktails and drank them both in quick succession.

Knowing them, it will probably be complete lies, would explain how this happened. Poor girl.

The drink was a "nitro jagermeister" - Knowing how students/snowboarders drink/shoot jagermeister, I'd say the daily fail have got lucky on this one, they are probably right!

Come on, let's put this in context please. Hot water is dangerous in the hands of a child, HF is dangerous in anyones hands, N2 in a cocktail is entirely inappropriate and the dangers exist purely because a semi pissed 18 year old student will not realise the inherrent dangers of necking it.

I work with the stuff routinely. Boiling water isn't dangerous as such, spilling it in a confined space won't kill you. Spill liquid Nitrogen in a confined space,such as a laboratory, and it can lead to dangerously low oxygen levels and suffocate you.

The last sentence would lead most people to say yes liquid nitrogen in the wrong hands is dangerous. A bar does not need this stuff.

I feel we are breading a bunch of idiots who just want to go up town and get as drunk as possible in the shortest possible time.

Having said that, I wish her a speedy recovery, and hopefully others will learn from her experience.

We use all sorts of substances on a daily basis that have a potential to do us harm - boiling water, petrol, bottled propane/butane etc.

However we are used to dealing with these and by and large, are aware of the dangers and know how to behave around them.

Liquid nitrogen is not something the vast bulk of us handle on a daily basis - especially bar men and their customers. Unless you work in science or engineering, you will almost definitely be unaware of its properties and dangers.

It is a totally inappropriate material to be used in a normal everyday environment - and it certainly should never have been passed to a (possibly inebriated) 18 year old as part of a consumable product. It was reckless in the extreme and I do hope that this bar gets the book thrown at them.
