You know those hand warmers that activate in the presence of O2. I waas wondering if they can get to 120 degrees with the little O2 in the air what would happen if they were subject to pure O2 gas or thrown into a bucket of liquid O2? Im sure it would be violent. Damn I used O2 five times in one little paragraph.

LOX will kill you.
Many things that don't normally burn can light right up in a stream of pure O2 gas.

They are basically just iron filings, salt, and some insulation.

I am in no way thinking of doing this, just wondering about it. So it'll burst into flames? Possibly turn into a thermite type of reaction?

I've always contemplated running a stream of O2 into a supercooled condenser(with Liquid nitrogen as coolant). Interesting idea to say the least. Liquid oxygen would merely oxidize the iron at a faster pace than just normal air i spose. I wonder if LOX is the best oxidizer due to it being well pure oxygen.

I think you'd find that pure fluorine is probably the best oxidizer.

I think LOX is used in some type of explosive, I forget what it is called.

Also, you may be underestimating the effect pure oxygen can have on something. Consider that organic material can burst into flame/explode when high concentration hydrogen peroxide is spilled on it due to the radical oxygen produced rapidly reacting with the combustible.

Also, I've seen somewhere on the internet pictures of an experiment where a cigarette was soaked in LOX. It was then ignited and it burned in 3 seconds. The filter exploded.

Liquid oxygen and reactive fuels make, strangely enough, a class of explosives called oxyliquits. Really inspired name there, eh?

IIRC Somebody won an ignobel prize for getting a barbecue to cooking temp in less then three secodns... i think the fire chief in his city later stated that if he was ever caught within fifty feet of a flame source with liquid oxygen again, the fire chief would personally take an axe to him.

The barbecue was reduced to a small pile of red iron oxide.

:'D

Concrete?

Concrete?

Not usually, no. But things like steel wool, magnesium powder... Flammable items that usually require an oxidiser, strangely enough, tend to oxidise quite violently when exposed to pure oxyge.

For concrete, you'd need something like

pure fluorine

There actually used to be a vid on youtube about fluorine being sprayed across things like a stick of sulfur, etc, which was pretty freaking cool.

Anyone who has that vid... Feel free to link me up.

lox is used in rocket fuel as well as high performance air vehicles

I remember our local hospital having a huge tank of lox outside with a warning:

"Do not park your car in the vicinity of the oxygen tank, in case of leakage your car may spontaneously catch fire"

^ lol

and dont breath it in.

Got that at the Uni. Plastered in cryo warning stickers too, lol.

^ what uni u go to in perth?
