Liquid Oxygen Demo

[JetAce08]

pretty cool man, i am a cryogenic technician in the marine corps, we make and store liquid nitrogen and oxygen along with other things. Our plant uses LIN to produce LOX but your display was cool to see. Im kinda surprised the test tube didnt crack when ya diped it in the LIN from room temperature. You should see when we have to dump 400 gallons of liquid oxygen, the whole area is covered in about a foot of low lying fog, its pretty sweet.

How did you get it from the store? (I'm wanting to do research)

[itdoesntmatter30]

Did you have to show a permit for the liquid nitrogen ?

[jrbpyro101]

@itdoesntmatter30 Nope

[vmelkon]

What do welders do you liquid nitrogen?

[spotlightman1234]

@vmelkon they use it as a shield gas

[Huffdev]

where did u get the liquid nitro

[rubiksmaster78]

What would you use this for

[rubiksmaster78]

What would you do with this

[EdwardMarshall1982]

@rubiksmaster78 Rocket fuel.

[ianspaintpot]

what is your folks thinking of letting you play with liquid nitrogen dont they care

[jrbpyro101]

@ianspaintpot They care, but I am safe with it

[sciman001]

mine was darker...

[Ninja1127]

what if you drank that

[ACEGR1]

what happens if you drink it ?

[jrbpyro101]

@ACEGR1 It would freeze your throat and probably give you a nasty burn since it is a strong oxidizer

[ACEGR1]

@jrbpyro101 i expected the same , i just wanted to conferm that .

[canonfrog]

@ACEGR1 your lungs freeze and you'l die immideatly

Im looking into doing something like this myself, and what you have done here is really quite fascinating. I just need to get my hands on some oxygen for starters. I figure my local Praxair will be my best bet.

[jrbpyro101]

Try finding a welding store. Praxair may not sell to you unless you have a company.

[zeradiddle]

Thanks for the info. Where do you obtain your liquid nitrogen?

[jrbpyro101]

@zeradiddle I buy mine from a company called united states welding. Just look up welding stores in the phone book and call around, it took me a while to find a store that would sell so you may have to do some research.

[soundagenda]

great vid. :)

[Grundalizer]

who buys you this shit?

[jrbpyro101]

I usually buy myself this stuff

Oxygen will become solid at −361.82 °F under atmospheric pressure. Im not sure whether there is a freeaing point or notfor oxygen. Ive read that there is a freezing point but Ive read two different temperatures, -361.82 F and 297.3 F. I have also read that there is no freezing point for oxygen, im not really sure. If you would like me to do more research let me know! There is a freezing point for hydrogen and at 1 atmosphere it is -434.5°F and hydrogen will become solid.

[liquidgrain]

try putting a glass tube directly into the bottom of the test tube so the O2 bubbles through the lox.

[jrbpyro101]

Thats a good idea thanks!

[clagwell]

Excellent work !

[jrbpyro101]

thanks

[jrbpyro101]

I did loose oxygen through the other hole and the reason that i did that is the minimum i could run the oxygen in there was .5 litres per minute and it wouldnt liquify that fast so it would just blow the stopper off. I made the mistake of NOT putting a hole in it and it blew the stopper off and hit me.

[jrbpyro101]

for that little amount, about 3 or 4 minutes.

dude the camera thing is sqeuky

[jrbpyro101]

ya i know the tripod kinda a piece of junk
