Preparation of liquid oxygen

Please make liquid hydrogen like you make liquid oxyden

Always?

Is water blue because of oxygen?

If you drink it, your mouth will probably we freezing cold, your body temperature will turn it back into normal gas oxygen within seconds, but since we shouldn't breathe pure oxygen...it will be a problem

I see, thanks!

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)

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

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

Are you speaking from experience or just out your ass? I work with oxygen every day. If you stick a lighter in front of oxygen if blows it out unless it is a very tiny amount and then you might see the flame turn white, but it does not grow it will actually get smaller as it burns hotter. Oxygen is the accelerate for the combustion. That's neat you know what a combustion reaction is.

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.

Where did you get your Lab equipment for this?

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)

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

that is completely untrue, in fact... liquid oxygen is even more flammable than O2 gas. I have seen someone place a lit match into a test tube of liquid oxygen and it went BOOM!!!! also, in science... there is no such thing as cold... there is only such thing as lack of heat, and your hypothesis about the cold or lack of heat can be disproved in more than just this case due to the fact that rockets burn liquid hydrogen which is also extremely lacking in heat (or is very cold as you so put it).

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.

NEAT.

@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 :)

now just mix it with kerosene :D...

Why no burning test?

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