Preparation of liquid oxygen

Liquid oxygen prepared by condensing of the gas in the liquid nitrogen.

Wow, that's a lot of it! Great video. I love Your brand new - looking equipment, shiny and unstained. I am hungry for more :)

People discussing about it being flammable, fire needs oxygen, no oxygen = no fire, much oxygen = much fire. If you put a match in there if you managed to be fast enough the flame will get bigger since it has 5 times more oxygen than usual. It only won't last long since the oxygen is gone very quickly.

A whole swimming pool of this might get you a nice blast.

Probably some people are also mistaking this by liquid nitrogen. (the liquid used to cool it) (which includes no oxygen for a fire)

This will boil at -180°C, when you would drink it it would have vanished before even leaving the flask. (not vanished, it would be pure oxygen that mixes with the nitrogen and other stuff in the air quite fast)

@tamkakit1233 since it is liquid, it is obviously very cold. therefore burning it by dunking a match in it wouldnt work. only the gaseous oxygen would burn, which you can see in any other oxygen vid. great vid, love your stuff. a bit callous in the Ln2 handling in this and other vids but cool anyway. i subscribed :)

yes however thats not the main thing we breath in, we breath in about 70 to 75 percent nitrogen, 20 to 23 percent oxygen and 2 to 10 percent other gases such as CO2.

Oxygen does not "burn" as you say, it is an accelerant. Combustion is a chemical reaction where oxygen is an input and water co2 and heat are the product. I blow glass, I use propane and oxygen. You cannot light oxygen on fire, rather oxygen makes the fire happen quicker. I can turn on the oxygen and put my lighter in front of it and it will blow the flame out. Oxygen itself is not flammable. If you need a video to prove it ill post one.

I thought rockets just store hydrogen in its liquid form for saving space, and the excitement of atoms near the nozzle of the rockets transfer energy (as heat) and turn it into a gas, which then burns. You are probably right though. And when you say that liquid oxygen is flammable, just the vapors of gaseous oxygen being released as it sucks up kinetic energy from nearby objects is flammable, just like how gasoline is not flammable, but the vapors are. (look this up if you don't believe me)

An oxidation reaction involves the ion count change by the way, not combustion.

oh believe me, this stuff burns like hell on earth... u have to be extremely careful with this stuff.

Where did you get your Lab equipment for this?

[LTG]

I'll be that guy. What happens if you drink this?

Please make liquid hydrogen like you make liquid oxyden
