Welding in an iron pan full of liquid oxygen

Try running a plasma cutter using 100% oxygen instead of compressed air

I’ve always found compressed oxygen much scarier than liquid oxygen, especially at high flow rates. Definitely agree with your reasoning at the end there

Cody: Mad enough to play with liquid oxygen; smart enough to keep the guard on the angle grinder.

A negative result is just as scientifically valuable as any positive result. Really enjoyed this - would be keen to have a whole series on "will this burn in liquid oxygen?"

I recall Adam Savage from Mythbusters talking about a myth they decided was too dangerous to test full scale. A LOX tanker truck crashed on an asphalt highway and caught fire. The LOX spills out and saturates the asphalt. The combination results in the road exploding (not burning vigorously, exploding). They apparently did some small scale testing and decided it was way too dangerous to scale up due to it being unpredictable and expensive. Might be a fun thing to try at small scale. Or maybe it's a terrible idea. You can find a video of Adam discussing this by searching for "Adam Savage Answers: What's a Myth You Won't Test?" on YT.

Now we just need some bonus video of you frying some mushrooms in the freshly polished and seasoned pan. Don't imagine there's many skillets in service that have seen LOX before!

Yeah, once you get a cut going with an oxy/fuel torch, and get the oxygen flowing, you can 100% cut off fuel to the torch. The heat from the exothermic reaction of the oxygen burning the steel, is enough to heat the surrounding metal to liquid, which then reacts with the oxygen, continuing the the cut! it takes a steady hand and some practice, but you can cut for feet, with only a few seconds of fuel at the start to get the reaction going! What's really neat, is this is how those demolition rods (oxygen lance, thermal lance) work. They're a tube of steel, surrounded by thin metal wires/mesh, inside a larger steel tube. One end of the rod goes to a holder, to blow oxygen through the tube to the tip. They usually have a copper contact for the tube connection, that goes to a wire. You light the torch up, using a car battery connected to that wire, or a welder, or whatever. Just enough to arc/melt the corner, and the oxygen does the rest. You can also light them with a torch by heating the end. Then they're self-sustaining (well, with the flow of oxygen). The burning steel is directed forward, along with a high velocity jet of now pre-heated oxygen! So this extremely high temperature jet of o2, along with burning steel, is then used to cut through almost anything. Huge feet-thick chunks of steel, concrete, stone.. doesn't matter. It burns through EVERYTHING. And it runs on only oxygen, the tube itself is the fuel. They even work underwater! They're used in the heavy equipment/mining, demolition/junk/scrapping, and ship worlds quite often! Search youtube for 'thermal lance' or 'oxygen lance' videos, they are VIOLENT, DISGUSTING, DIRTY, AMAZING things. Sadly, I've never run one, only high current arc gouging and plasma gouging, which is comparing a match to a 100 ton ironmaking furnace!

One of the most interesting things I've seen with Liquid oxygen was a demonstration where they soaked a cigar in it and lit it on fire. Using it to burn a hole into an Aluminium plate. Really shows how things change with extra oxygen.

I’m so happy to be seeing Cody again Totally does the kind of stuff me and my friends do for fun

I haven’t had time to watch in a while but I am glad to see you are doing so much better. We like to see Cody happy.

Nothing is more peaceful than your intros nice job Cody

I saw the title, and figured "this is a bad idea, I'd better watch it". Well worth the time. Thank you Cody!

An interesting one, on demolition ranch he shot some oxygen cylinders and all of them ended up with perfectly circular holes way bigger than the bullet because of the steel burning. It's a really cool video

It’s amazing how you make ordinary objects seem so extraordinary. Thank you for always making learning new things fun

You gotta love Cody's "I'm about to do something crazy" smile at the beginning

Love how you experiment with things that sound dangerous but actually have a smart reason to test out. Great content as always!! Very entertaining to watch

Gouging rods would likely work in these conditions. They don’t have flux and do a similar job as an oxy/acetylene torch.

I truly enjoy your 'I wonder what will happen if...' videos. Never change, Cody. You're one of the most unique 'tubers on the platform. and its obvious you're wicked smart. Just avoid yellow chem, and you'll be fine.

I've always described Cody as a "mad chemist" but this takes is a highlight!

Only Cody is brave and smart enough to prove such things like this one here...
