Can anyone tell me how to get(make) liquid nitrogen.........? Oh and you can get large amounts of hydrogen by burning Na in water but the problem with that is that the heat from the reaction could burn all the hydrogen

why do u want liquid nitrogen? dumbass.

step 1: get nitrogen
step 2: make it really really really cold

and... what's your point with the hydrogen thing?

It would be a lot cheaper to make hydrogen with Hcl and tinfoil.

Or you could make more, totally pure hydrogen by electrolysis of water...
I'd also really like to see you try to make liquid nitrogen - the only way you're gonna do that is by lots of cooling and lots of pressure and then do a fractional distilation at liquid nitrogen temperatures... not gonna work, sorry!

I probibly shouldn't tell you this, liquid nitrogen is pretty dangerous, but if you can find someone in the oil drilling industry he might be able to hook you up, keywords "nitrogen frack", what the hell do you want it for? Other places to try would be doctors offices (used for burning off warts) and you could always just go buy some from a liquid gas supplier, but its not like you can just pour it into a mason jar and stroll off.
