Some Cheap Yuks with Liquid Nitrogen

I got quite a lot of msgs saying they liked the stuff in the lab, so I figured I would see if another such vid. got a similar reception.

While passing through the UK I did some work in a lab involving liquid nitrogen. The stuff is dirt cheap and an invaluable tool of science, however its also fascinating stuff to play with and there is always some left at the end of the day :-) . Naturally there are some hazards to handling liquid nitrogen, but to be honest, there are larger hazards from fueling your car yknow pumping 10+ gallons of highly flammable liquid into a, typically plastic fuel tank.

Anyways some cheap yuks with liquid nitrogen enjoy! ;-)

I overclocked a Pentium 4 to 6 GHz using this stuff back in the P4 era.

Wearing gloves is actually more dangerous than not wearing them. Gloves can trap the liquid nitrogen and increase the risk of getting cold burns. Besides, even if you do get some on your hand, the nitrogen will instantly vaporize, and a layer of gaseous nitrogen will form a protective layer between your hand and the liquid nitrogen and protect you from frostbite. This is called the Leidenfrost effect.

@Thunderf00t

i'm a little puzzled. you said it was the water/ethanol vapour? from my (relatively small) experience with the stuff, what you're seeing is the boiled off nitrogen. sure, there'd be a small amount of the other vapour in there too, but it would be in relatively small concentrations since the vapour pressures are much lower, and boiling points much higher...

correct me if i'm wrong though...

@rahagbab in common language yes but in this context by thick he means, well, thick light. cannot easily pass through it. and by dense he means molecularly dense, heavier for lack of a better synonym although weight has little to do with the matter.

[DtTV94]

@rahagbab Not really. Thick can be a measurement of size i.e one brick can be thicker than the other. But dense is more about, maybe in terms of bricks, more brick, less pockets of air... I have a terrible way of explaining it, I apolagise. But Im very sure Thunderf00t could explain it in a heartbeat!

[rahagbab]

I thought thick and dense meant the same thing.

wait ignore the comment i deleated. I just remembered it was Liquid ammonia not LN2

[coldcapsicum]

I try to wait for very low-humidity days to work with lN2 if possible, you can see what you're doing much more easily.

[fuzzydude64]

I wouldn't mind seeing more chemical experiments like this!

Liquid O2, way more fun!
