Elementary Productions: Liquid Oxygen

Jan 15, 2010 - this is cool but how do you get liquid nitrogen?

Feb 22, 2010 - haha there should be another tutorial and so on

Mar 24, 2010 - what were to happen if you drank the oxygen ? despite your stomach freezing ?

vmelkon Says:

Apr 8, 2010 - I don't think that any ozone would form at that cold temperature. Also, there is concensus that LOX is light blue and liquid and solid ozone is dark violet. I have never seen liquid or solid ozone but I once read that it is dark violet in some chem dictionary.

May 28, 2010 - When I was in the Air Force, we serviced the C-130s with Liquid Oxygen (LOX). They told us about "The Man from LOX" who had a cigarette shortly after servicing LOX. You were not allowed to smoke for at least a half hour after servicing because the oxygen would evaporate and get into your clothing. Apparently this person didn't obey this rule, and yes, the guy did die.

Jun 27, 2010 - holy crap don't you realize that all forms of flame energy need oxygen and haveing a pure form of oxygen means that it is able to feed large quantites to to any flame and will expand it in a massive way

TheLiberalSoup Says:

Jul 11, 2010 - why didn't nitrous oxide form?

MrCantThinkOfAName Says:

Jul 16, 2010 - Okay so today, i started out with nuclear fallout consequences, then to nuclear bomb videos, then to kittens, back to bombs, then to liquid nitrogen, and now this. odd.

mewrox99 Says:

Aug 21, 2010 - The reaction of nitrogen and oxygen require a lot of activation energy as it involves breaking the N to N triple bond. So oxides of nitrogen do not form at STP

TheLiberalSoup Says:

Aug 21, 2010 - cool, thanks

Aug 22, 2010 - Oxygen does not spontaneously "trimerize"; O3 has a positive heat of formation and will not form without major energy input. Also, it is not a simple grouping of three smaller units, it requires splitting an O2 molecule into atomic oxygen, which then reacts with another O2. Liquid oxygen contains no O3, not even parts per trillion.I work with LOX routinely, and have let samples boil off many times. It does not darken.

Aug 27, 2010 - Nice video. A better way of making this setup is to use a closed system. It seems that you just had the pipe sitting in the bottom of the test tube and the gas flowing past it. You can hook the flask containing the H2O2/MnO2 to a t-piece or y-piece adapter and connect a balloon to one end. Then attatch more tubing from the t/y-piece to the LN2 submerged test tube with a rubber stopper in the top. This way the sealed system wont lose O2, and the balloon will prevent too high pressure by expanding

Sep 20, 2010 - So if a cigarette burns that fast with extra oxygen, imagine how fast fires burned 300 mya when the percentage of atmospheric oxygen was roughly double at 40%. (This allowed dragonflies as large as a large dog and primitive crocs as large as great white sharks to exist.)

GroupWizard Says:

Nov 19, 2010 - Becuse you have to react the oxygen and the nitrogen together and here you are not reacting them you are just useing the nitrogen as a coolent

purplemutantas Says:

Dec 20, 2010 - The easiest way to get liquid nitrogen is to buy it.

Jan 14, 2011 - theres to many smart ass's on youtube

pyro4869 Says:

Jan 29, 2011 - i didn't know you could drink air !?!!?

dmx952 Says:

Mar 13, 2011 - i dropped chemistry :)

vitorix24 Says:

Apr 24, 2011 - Find some company that sells liquid gases. like N,O,He

nicktohzyu Says:

Oct 12, 2011 - FINALLY someone uses h202 instead of vanadium(V)

nicktohzyu Says:

Oct 12, 2011 - btw doesnt have to be manganese dioxide, both KI and yeast would work as well

DaBeast842 Says:

Oct 26, 2011 - that cigarette is on stereroids

MucusFelidae Says:

Oct 31, 2011 - Apollo1 mission combusted three astronauts in pure oxygen atmosphere of the cabin. Those american NASA engineers were stupid assholes. Remember, space travel was developed by Germans firsthand, when the Americans took over, they produced lethal fireworks.

Dec 25, 2011 - that is so fucking cool i can't believe, wondered if there was solid O2, and there it was. thx for sharing
