wat happens if u mix nitorgen and water?

Liquid nitrogen boils at -196°C. It has an expansion rate (that is from liquid to gas) of around 850 (ie it will take up 850 times the space at normal pressure).

That was a pretty foolish thing to do - did anything come of the security guard thing, or was it just left alone?

 

[Xayma]

The security guard said nothing will probably come of it but he still has to pass it up the chain etc.

 

[gordo]

but did the water have anything to do with it?
i thought thats wat u were implying initially?

 

[Xayma]

Well when they realised that it was going to blow (dont know what they were thinking before hand) they tried to grab the lid off the top.

If it was just liquid nitrogen it probably wouldve been possible to do (since it will cool the surrounding bottle and slow the boil) but the water means it occurs alot quicker (high heat capacity etc as well as being imcompressible).

actually.. i think it was an empty coke bottle..

the guy said their security system sensors registered all the eastern ave. windows as "shattered".

and i bet you also had your hearing impaired xayma?
haha the OH&S people must've been shitting themselves..

 

[Xayma]

No actually I wasn't there at that moment so this is what I've heard from them and others there, I was just grabbing some paper towels from here so we could actually clean up the tables...

lol interesting idea...

infact, this design is not far from an actual bomb, less the vast amount of energy being produced...

 

[Xayma]

Yeah it is just a CO₂ bomb on drugs. As to C4 and the like it's pretty much the same.

 

[einsteinthe2nd]

what time did this happen?

 

[Xayma]

Umm in between 3 and 4 cant remember the exact time.

 

[Eagles]

[ameh]

I was wearing red shoes and held a blue balloon, went to the engo free bbq and the liberal studies lecture.
