  • I believe you are mistaken about the reason LOX is blue. It is not because of the ozone, oxygen itself has some absorption lines in the red, which gives a blue color. Try your experiment with pure oxygen - I predict its liquid will still be blue. Try another experiment: let it distil away to nothing. Liquid ozone has a much higher boiling point than oxygen, and would concentrate as time goes on (the color would darken) if you were correct.

  • Pure liquid Oxygen will always contain some Ozone, as it trimerizes. Also, liquid Oxygen does darken upon evaporation, due to the reasons provided by yourself :)

  • this is cool but how do you get liquid nitrogen?

  • Oxygen is NOT flammable! It is an oxidizing gas, and will therefore NOT burn by itself!

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

  • 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.

  • that cigarette is on stereroids

  • btw doesnt have to be manganese dioxide, both KI and yeast would work as well

  • FINALLY someone uses h202 instead of vanadium(V)

  • @bluefox216 Find some company that sells liquid gases. like N,O,He
