I love your videos and I've been watching them for a long time now. The fact that you even show your failures makes you one of the very few "good guys on youtube" for me so please, keep up the good work! Much love from Germany :)
I work the cryogenics plant in Panama for the Air Force. We used a Compressor to pull in air, compress through 5 chambers, refrigerate the gas, pass the gas through silica gel to remove moisture, then blow to vapor into a tray tower. This would super cool the gas into a liquid. The nitrogen and oxygen would separate and we could store each into storage containers. This works off the principle of Increased Pressure = Increased Heat / Decrease Pressure = Decreased Heat. Keep up the good work.
Cody, my name is Patrick Gaines and I'd just like to say that you're a brilliant person and in all honesty the main reason I'm continuing me educational career. I've been obsessed with sciences of all sorts but the school systems where I live arnt to found of teaching these kind of things. For about 4 to 5 years I've been cunducting my own experiments in my home (the first being the extraction of bismuth from pepto bismal) and I'd just to give you thanks for being a legitimate educational sorce and I'd nothing else a motivator. You're a genius man, thank you so much sir.
Muzik Bike - Geometry Dash and stuff producing iron out of blood seems possible. Drying, heating it up to several 1000degrees and add charcoal to remove oxygen. A very weird way to obtain your pickaxes iron.
I just wanted to say thanks, partial because I love these videos, but also because you show when something doesn't work. I love that. It makes the learning process so much more fun when stuff doesn't work the first time.
Cody , Bro. you have inspired me. im saving my old PC parts so I can later recover the metals. your videos have given me so much information and knowledge. thanks for every video!!
Dude I dunno if you've tried since, this vid is several years old. But you can easily get yourself liquid oxygen. You have to buy a large dewar unit which is usually around 1300ish, but then you can just have them deliver and fill. Or truck the dewar out to get it filled. If I recall, you live in CO somewhere near Denver. Look up Buckeye Welding. They're amazing! Many of us glassblowers regularly purchase and use LOX or compressed oxy for fueling our torches! Airgas is an elitist and horrible place to get any gas or supplies unless you're buying industrial volumes.
Wonder what the million subscriber video will be. Actually, the fact that a million people are subscribed to this channel is great. Shows you don't need frantic video editing, great quality camera work, multiple people, etc to create a product people enjoy.
Almost a million subs... Wow. All I can say is that you deserve it. I've been around since episode 1 of your refining precious metals series and you didn't even have half of what you have today!
jamie o'brien increased surface area by Fick's Law increases the rate of exchange in this case of heat, so he's getting maximum cooling effect over a short distance on the oxygen by coiling it
+LHommeDeCave Not really Fick's law, it's just convective heat transfer. q = hA(Ti - Tw). h is the heat transfer coefficient, A is the surface area in contact with the fluid, Ti is the temperature of the main flow of fluid, and Tw is the temperature of the surface.
Cody, I used to do this alot (work at power plants where we have tanks of liquid N2 to blanket our steam drums to prevent corrosion when not running) just for fun. Typically immersing a test tube in LN2 and putting pure O2 gas inside the tube to allow it to condense (from an oxyacetelene rig). The LOX will be a pale blue color when it is pure, not clear. You have probably figured this out by now, but I just wanted to mention it. Love your videos. Keep them coming!
you make me wish I graduated high school man. you've made something thats confounded me all my life so fascinating. If your channel were a book I don't think I could put it down!
Cody : best TH-camr ever ! Every video you upload gives me this exhilarating feeling I felt when I was doing experiments as a kid. I wish I had the tools necessary to build cool things like you do (I wish I had an hydrogen and oxygen generator).
Yeah I know for the NaOH/Aluminium method, but I'd prefer electrolysis. I kind of wanted to create a O2 + H2 gas generator like the king of random did too... but I just don't have any tool here in my flat, for this. Nothing to cut, nothing to weld etc. But this was just an example... I'd like to build a lot of other things. But watching Cody kind of relieves this will to build things and do experiments I've had my entire life !
Cody you could have brazed the stainless steel to copper no problem. You just need to use a brazing rod for that application. You can braze ALL dissimilar metals together as long as the alloy turns liquidus before the base metals being joined. Also having clean surfaces prepared before you start. Another cool thing is that if the gaps between the parts is a very tight fit you only need a tiny bit of brazing to fill it. The tighter the tolerance and the thinner the brazing, the stronger your joint will be. More isn't better.
Light1500 it's not methane, it's CO2. The tank still has oxygen in it so the bacteria are doing aerobic respiration. For methane to be produced there must be no oxygen in the tank so the bacteria respire anaerobically.
Great video, good job. I was wondering if a magnet were held in place (by another magnet possibly through a wood board) and there were 2 other of the same magnet aiming at it from different directions, would it be able to spin forever without any help? (sorry if that description was super confusing)
+creapycreaper101 Nope. There is no such thing as doing something "forever without any help". In fact, that configuration would just lock the magnet in a perpendicular position to the other two.
Good video, I was unaware that you couldn't purchase liquid oxygen. When I was in the navy we serviced our aircraft with LOX (liquid oxygen) it was added to small round green bottles (about the size of a basketball) the service carts had large cylinders that were pressurized to 5000 psi all the wrenches and other tools were made of brass to prevent sparking. Occasionally some of the LOX would spill on to the ramp when the lines were removed while filling. and a buddy of mine decided to stomp on one of the larger drops of LOX and it blew the heal of his LOX boots off funny as hell to see his leg jump up when it happened.mid enjoy your video's keep up the good work. Don't let the easy u tube money distract you from your potential contributions to the betterment of mankind. Have you done anything with graphine? I believe there is allot of potential in Graphine.
I saw a while back a video showing of the first people (scientists) that were competing to be the first to get to 0º-kelvin. And it was mainly done, of course, by liquifying gases. And if i remember correctly, it was Dewar who had an apparatus of various stages of liquifying different types of gases, in sequence where each one had a lower liquid point than the previous. A chain of liquifying gases. Up to Hydrogen, and then Helium (which he didn't get to). But i'm saying, maybe you could try this, because the gases were not wasted. And you could maybe hook it up to a solar panel with a compressor, make it self running. IDK. I do know it's a lot more woork XD. But hey, you're here to work for our entertainment right? hehe :D
DissectedPig I sense you were thinking i want him to attain 0 kelvin. No. I'm just talking about a machine so he can get liquid Oxygen without having to buy/waste Nitrogen.
Gustavo XD you are correct about Mr. Dewar. This is why any container designed to hold a type of compressed gas/chemical is housed in what we call Dewar's.
Hi Cody, i really hope you read this, I'm in my 3rd year of theoretical physics and just finished my 6 month project on solar cells, but i've noticed that unless I make one my self i dont really knownthe struggle of manufacturing one, although i know how they work and everything, it just seems like i'll never get my hands on one, now i have a request and a big favor, if you could make a series on harvesting materials required for building one (silicon will be difficult to harvest) because it seems like nothing is impossible to you and i'm just dying to watch a video like that on internet and couldnt find it anywhere, no one has made a silicon solar cell from scratch. I love watching your videos and think that you teach people so much about the real stuff and how things are made and not only focus on the theory, really like this channel for that.
9:10 Me and my friend once planned on building a model rocked using ethanol and oxygen as fuel. When we went to buy the oxygen (we both were 15 at that time) we asked the dude from the hardware store if we were even allowed to own 350 liters of oxygen (compressed into two .9L bottles) and he just said "Eh.. A little bit of oxygen never harmed nobody.." i suppose rules for that just aren't that strict in europe..
Hey Cody just wanted to thank you for making videos. I look forward to every single video and have been since quite a while ago. I think around 15k subs. But, never mind me. Just keep making videos and keep being awesome Cody:)
well... if you can buy liquid nitrogen oxygen is the main component of rocket fuel so yeah... unless you want people able to make bombs very easily don't sell liquid oxygen
☼ Heirloom reviews ☼ I am wondering the same thing. Don't the tanks of oxygen that people with respatory illnesses use have liquid O in them? What "bad stuff" do people use it for to make it regulated?
What about putting it in a centrifuge? Do they have significantly different densities? Will it be practically unfeasible to try to separate them this way?
Nice work Cody, and I just love the comment threads that your videos spawn. Almost as entertaining as the videos themselves! I know it's a bit late, but Happy New Year to you and yours.
It blows my mind how many videos you put out, and each one of these projects being something an average person would likely individually take awhile to complete.
Probably because liquid oxygen is very dangerous , and you maybe need to have some kind of license or business to buy it. Nitrogen is not reactive/dangerous.
Hmmm... Well, oxygen sure is dangerous, but actually, everything can be harmful in the wrong hands. It's probably what you've said "and you maybe need to have some kind of *license* or business to buy it."
Hey Cody, I did a bunch more testing with the liquid Oxygen today, and I discovered a reaction I think is definitely worthy of video, as I couldn't find it anywhere. Kerosene and Liquid Oxygen. It explodes very quickly. I dumped an unmeasured amount of Lox into a tin can containing kerosene, and lit a fuse. Maybe 200 milliliters of the stuff created a fireball/flash about 25 feet tall. Definitely try it out.
He tried making a coil gun which works on the same principle... It did propel the projectile, but not fast. It's not the simplest thing to get working well.
Yeah, coilguns need a long distance to build up proper speed. Railguns can go much quicker over a shorter distance, but they produce an outward force on the rails which makes engineering them a nightmare.
I did this same experiment when I was in high school and I didn't need to build any fancy equipment. I very simply filled a large styrofoam cup with liquid nitrogen and placed a bunch of empty test tubes in it, mouth up. Oxygen with some argon started condensing inside them. Of course there was some water ice/dry ice in it though. I then combined all the test tubes together and it filled one all the way. It was pale blue and magnetic. Igniting paper in it actually exploded and I have a small scar from it.
Hey Cody, I have an experiment to think about if you are interested. It involves Foam Metal tubes wrapped in carbon fiber, and filled with Hydrogen at pressure. It is meant as proof of concept that you can build a strong low mass framework for a vehicle that acts as the fuel cell to power itself. I think something as small as a few oz would be enough. And it doesn't have to perfectly seal. I believe a rigid frame saturated with Hydrogen could be scaled to any size that would power mechanical force more efficiently than any foreseeable battery technology. Also the Methane would kill your animals long before there was any danger of explosion. A bit morbid, but at least you never have to worry about an explosion.
Back when I did LN2 demonstrations at my local science museum one of my fellow demonstrators brought in a cheap wok to make it easier to cool and shrink balloons. I noticed a constant drip coming from the bottom of the cold wok. On a hunch I collected some in a test tube and got a pale blue liquid with white particles that settled to the bottom. I did a splint test and the glowing stick burst back into flame,.
+Lewis Massie: That's probably a bad idea as well unless you open up the oven door once in a while or just poor 90 °C water on the pipe and the propanone will boil away.
Liquid oxygen is used to treat a variety of respiratory conditions. It is safe to breathe. However compressed gas is a much more common method of supplementary oxygen delivery. I work for a respiratory/home oxygen company.
oh! well my shitty 4g only lets me watch in 480p couldnt really tell. but my question is would lowering the temperature even more make it deeper blue color?
Love these videos. A follow up, it it hasnt been done yet, would be to separate H and O2 from water through electrolysis and chill the gas as it escapes. I cant help but think, submersing your welding O2 in liquid nitrogen would be easier than chilling the gas as it passes through the tubing. but then it leaves you with a cold sealed tank of O2 that you need to poke a hole in.. Maybe thats not such a good idea after all.
mrtyrese05 quote: "Caillou is a despicable, spineless 4-year-old boy who cannot do anything. He can't grow hair, not because he has cancer or progeria, but because he sucks, and even his own body recognizes that he does not deserve hair or food or love."
The dioxygen molecule (O2) has a couple of unpaired electrons (one for each oxygen atom) which gives the molecule a dipole and makes it susceptible to magnetic fields. This isn't just true of liquid oxygen - gaseous oxygen has the same properties, but in the gas phase the material is not dense enough and the molecules have too much energy - they are moving around too fast for magnets to hold onto them. Liquefying the oxygen not only removes a lot of the energy but also increases the density by a factor of almost 800, so the magnetic effect becomes much more apparent. Technically, oxygen is paramagnetic. This means that it has no magnetism of its own - it cannot attract steel objects, for example. But in the presence of a magnetic field, the dipoles in the oxygen molecules align and become magnetic, which is known as magnetic susceptibility. The result of which is what we see when liquid oxygen is brought near a strong magnet - it sticks to the magnet. The effect is similar to ferromagnetism (seen in iron, steel, nickel, cobalt and rare-earth magnets), but a lot weaker: It takes a powerful rare-earth magnet to have much of an effect on liquid oxygen - a conventional and much weaker fridge magnet barely interacts at all.
dude Cody- California transplant who watches every single upload. I laughed and laughed about "boy that's embarrassing isn't it" it's such a Utah thing to say. thank you my friend! very funny!
Robert Hathaway I know that but forget the temps, what would it do in your stomach, like, would it boil and you could breath it in, or would it sit there and just evaporate and circulate?
It would immediately start boiling in your stomach releasing a lot of gas because liquid oxygen contains 4000x more oxygen then what you are breathing in from the air, which would build up pressure. This pressure would likely travel up your esophagus into your lungs causing them to collapse as well as tearing holes in your stomach. yes it will very likely kill you
A way to purify the oxygen from the air is to use the same principle of a water smoke pipe but fill with nitrogen. The water will froze at the entry and form ice that will stay in the bottom of the jar. The the magnet you have and gravity (Oxygen is heavier) to separate the small amount of oxygen from the nitrogen. The Nitrogen melt at -210 °C and Oxygen at -218 °C. By the way, I love your videos of DIY materials production.
RuNe Voltage i mean, if it wasnt for the fact it would freeze your insides if you breathed or drank it, it probably wouldnt do too much harm, though there may be some issues with something so magnetic being in your body, simmilar to how people die if they consume small magnets from having crushed organs. it is noteworthy to say that drinking liquid oxygen wouldnt be the same as breathing
Believe it or not, oxygen is very toxic in above normal doses even when breathed in at atmospheric pressures. If the oxygen isn't used up or expelled from the cells fast enough radical species can build up quickly and initiate peroxide chain reactions causing all sorts of havoc.
I solder to stainless fittings to kegs for brewing all the time. Use Harris Stay Brite #8 solder, Harris Stay Clean Liquid Flux, and keep it VERY clean with some surface abrasion to get through the passivated layer. Cleanliness is very important (much more than Cu soldering) and the Harris products are high silver content compared to regular solder. But if your parts are clean and you use the harris stuff, it solders even easier than copper because to lower thermal conductivity keeps the heat where you want it and you can walk it around. It's easier to overheat stainess soldering than copper though for that reason too.
I'm kind of feeling Cody's going to build a warp drive eventually from pipes, nitrogen cooling, electricity, and old microwave, magnet array and some disco lights. Nice one butt. Enjoy your inventions and video productions 👍
It is actually extremely easy to silver solder/braze stainless steel with BAG24 silver solder and white flux. I have made Stirling engines using stainless steel water bottles in this way. I have braised or soldered most metal combinations including aluminum to stainless steel and honestly stainless steel with BAG-24 was probably the easiest to do other then copper.
The mark of a true backyard scientist, "I can't buy liquid oxygen, I have tried, but they won't sell it to me.... So I will just make my own."
Yeah, it's because O2 in liquid form will still react...Oftentimes explosively.
@@rainiersauer4288 pretty much what happened with the Challenger, LOX mixed with the hydrogen and reacted, Kaboom
@@projectdelta50 That happened with all the shuttles.

James Over Yonder that's called a iron lung like he said it's compressed it's controlled by air pressure plus if one blows up well rip
Cody if you make a roket powered with liquid oxygen, mygod you're the man!
What about using a magnet to separate nitrogen and oxygen apart? Or would there still be bits of nitrogen mixed in?
A mixture of nitrogen and oxygen is just less magnetic; no separation occurs.
What about putting it in a centrifuge? Do they have significantly different densities? Will it be practically unfeasible to try to separate them this way?
Awesome Cow they do not at all. They are next to each other otithe periodic table.

Matheus I agree
Matheus because it's super explosive and reactive
I live my (wished to be) life through your eyes. Thank you
last time I was this early Cody hadn't eaten metal yet
Hey Cody, I did a bunch more testing with the liquid Oxygen today, and I discovered a reaction I think is definitely worthy of video, as I couldn't find it anywhere. Kerosene and Liquid Oxygen. It explodes very quickly. I dumped an unmeasured amount of Lox into a tin can containing kerosene, and lit a fuse. Maybe 200 milliliters of the stuff created a fireball/flash about 25 feet tall. Definitely try it out.
Cody, you need to try making a railgun
He tried making a coil gun which works on the same principle... It did propel the projectile, but not fast. It's not the simplest thing to get working well.
Yeah, coilguns need a long distance to build up proper speed. Railguns can go much quicker over a shorter distance, but they produce an outward force on the rails which makes engineering them a nightmare.
I did this same experiment when I was in high school and I didn't need to build any fancy equipment. I very simply filled a large styrofoam cup with liquid nitrogen and placed a bunch of empty test tubes in it, mouth up. Oxygen with some argon started condensing inside them. Of course there was some water ice/dry ice in it though. I then combined all the test tubes together and it filled one all the way. It was pale blue and magnetic. Igniting paper in it actually exploded and I have a small scar from it.
Today I learned that liquid oxygen is magnetic.
Woooooooow Cody will get 1mil subs soon !!!! Congaratulate Cody!!!
Why don't the welding shops sell you liquid oxygen? I'm curious. Can it be used to make a bomb or something dangerous?
yes
Cody'sLab hi
Cody'sLab notice me senpie
Cody'sLab pls replay I love you
seephor they usually only sell to business
I love all the videos about liquid oxygen, always so interesting!
You can probably make liquid methane with it too;)
Lo2 and liquid methane. Hmmmm.
Hey Cody, I have an experiment to think about if you are interested. It involves Foam Metal tubes wrapped in carbon fiber, and filled with Hydrogen at pressure. It is meant as proof of concept that you can build a strong low mass framework for a vehicle that acts as the fuel cell to power itself. I think something as small as a few oz would be enough. And it doesn't have to perfectly seal.
I believe a rigid frame saturated with Hydrogen could be scaled to any size that would power mechanical force more efficiently than any foreseeable battery technology.
Also the Methane would kill your animals long before there was any danger of explosion. A bit morbid, but at least you never have to worry about an explosion.
What experiment are you doing with the rabbits?
He is decomposing there poop to make methane.
Back when I did LN2 demonstrations at my local science museum one of my fellow demonstrators brought in a cheap wok to make it easier to cool and shrink balloons. I noticed a constant drip coming from the bottom of the cold wok. On a hunch I collected some in a test tube and got a pale blue liquid with white particles that settled to the bottom. I did a splint test and the glowing stick burst back into flame,.
Cody: "acetone is flammable"
*puts in oven*
+Lewis Massie:
That's probably a bad idea as well unless you open up the oven door once in a while or just poor 90 °C water on the pipe and the propanone will boil away.
Gotta love that MS paint intro 😂 great video man! Entertaining as always!
legitimate but slightly stupid question but what would happen if you consumed liquid oxygen in any form such as inhaling or drinking it?
You know if people keep asking this eventually I will have to answer. ;)
well i'm hoping it not's too dangerous in case it is then.
Liquid oxygen is used to treat a variety of respiratory conditions. It is safe to breathe. However compressed gas is a much more common method of supplementary oxygen delivery. I work for a respiratory/home oxygen company.
Thanks for no ads.
i thought oxygen under around -160 degrees C turns into blue liquid
It was, didnt you see? it is only very slightly blue.
oh! well my shitty 4g only lets me watch in 480p couldnt really tell. but my question is would lowering the temperature even more make it deeper blue color?
That Is one reason i want to re-do the solidification experiment, I dont really know.
Nice! i hope it is gonna be in a video?
wow 2 replies from cody
Cody's like a scientific child. It's a rare and beautiful thing.
Can u harvest mercury from apples
Love these videos. A follow up, it it hasnt been done yet, would be to separate H and O2 from water through electrolysis and chill the gas as it escapes. I cant help but think, submersing your welding O2 in liquid nitrogen would be easier than chilling the gas as it passes through the tubing. but then it leaves you with a cold sealed tank of O2 that you need to poke a hole in.. Maybe thats not such a good idea after all.
When are you planning to bring down that satellite??
really enjoyed watching this video. Keep it up Cody!
since your so smart can you please exlpain why caillou is bald
Congenital Hypotrichosis or maybe cemotherapy. Have to admitt i had to google what caillou was.
Alopecia universalis
mrtyrese05 quote: "Caillou is a despicable, spineless 4-year-old boy who cannot do anything. He can't grow hair, not because he has cancer or progeria, but because he sucks, and even his own body recognizes that he does not deserve hair or food or love."
i’m just a kid who’s 4, each day i grow some more, i like exploring im caillou.
Wish i had an intelligent question regarding science and your video; but it's nice to learn something every time so thank you.
why is liquid oxygen magnetic?
The dioxygen molecule (O2) has a couple of unpaired electrons (one for each oxygen atom) which gives the molecule a dipole and makes it susceptible to magnetic fields. This isn't just true of liquid oxygen - gaseous oxygen has the same properties, but in the gas phase the material is not dense enough and the molecules have too much energy - they are moving around too fast for magnets to hold onto them. Liquefying the oxygen not only removes a lot of the energy but also increases the density by a factor of almost 800, so the magnetic effect becomes much more apparent.
Technically, oxygen is paramagnetic. This means that it has no magnetism of its own - it cannot attract steel objects, for example. But in the presence of a magnetic field, the dipoles in the oxygen molecules align and become magnetic, which is known as magnetic susceptibility. The result of which is what we see when liquid oxygen is brought near a strong magnet - it sticks to the magnet. The effect is similar to ferromagnetism (seen in iron, steel, nickel, cobalt and rare-earth magnets), but a lot weaker: It takes a powerful rare-earth magnet to have much of an effect on liquid oxygen - a conventional and much weaker fridge magnet barely interacts at all.
1:41 I didn't know Infogrames made LOX hardware.
In all seriousness thanks Cody as usual for general awesomeness.
This idea of creating ur own oxigen using liquid nitrogen is very cool ! ........get it :P oh and .....BUNNIESSSSSSS!!!!!!!!!!! :3
dude Cody- California transplant who watches every single upload. I laughed and laughed about "boy that's embarrassing isn't it" it's such a Utah thing to say. thank you my friend! very funny!
What if you drink liquid Oxygen?
Hey-its-Dakota You would probably die due to the super cold temps.
Robert Hathaway I know that but forget the temps, what would it do in your stomach, like, would it boil and you could breath it in, or would it sit there and just evaporate and circulate?
it does you a cold
Sets you on fire methinks, if you disregard the temperature
It would immediately start boiling in your stomach releasing a lot of gas because liquid oxygen contains 4000x more oxygen then what you are breathing in from the air, which would build up pressure. This pressure would likely travel up your esophagus into your lungs causing them to collapse as well as tearing holes in your stomach.
yes it will very likely kill you
And yet another job well done.
Liquid methane?
subscribed since 82.000
I love you man! keep it up!
could you drink this while under water to breathe?
Jk
Arcade Master I'm so ashamed of you, get back in the basement. smh
I was just kidding
this is super cooled and would give you internal frost bite causing lots of problems
but couldn't you wait for it to become gaseous again?
A way to purify the oxygen from the air is to use the same principle of a water smoke pipe but fill with nitrogen. The water will froze at the entry and form ice that will stay in the bottom of the jar. The the magnet you have and gravity (Oxygen is heavier) to separate the small amount of oxygen from the nitrogen. The Nitrogen melt at -210 °C and Oxygen at -218 °C. By the way, I love your videos of DIY materials production.
Pardon my ignorance, but would liquid oxygen be safe to drink? My hypothesis would be yes, because it is safe to breathe, but I don't know.
RuNe Voltage i mean, if it wasnt for the fact it would freeze your insides if you breathed or drank it, it probably wouldnt do too much harm, though there may be some issues with something so magnetic being in your body, simmilar to how people die if they consume small magnets from having crushed organs. it is noteworthy to say that drinking liquid oxygen wouldnt be the same as breathing
RuNe Voltage it's cold
RuNe Voltage it would freeze your mouth, and then probably explode
*definitely secure approval sticker*
I didn't even think about the temperature. My bad.
Believe it or not, oxygen is very toxic in above normal doses even when breathed in at atmospheric pressures. If the oxygen isn't used up or expelled from the cells fast enough radical species can build up quickly and initiate peroxide chain reactions causing all sorts of havoc.
I really enjoy your videos. Keep up the good work.
Safety Sock!
I'm surprised the PPE warriors aren't after you yet.
Alex D they were
Alex D they came, Cody drank arsenic. They ran away quickly.
I always learn so much from your videos! Thanks for another great one cody!
Homemade rocket fuel. Seems normal
Speaking from the perspective of a technician who has worked on the freon systems, I can attest your brazing technique is pretty decent.
7:47 dude don't point that thing in your face... (o . 0)
Oxygen doesn't explode.
yes, yes it does.(well has the potential anyway)
No. Hydrogen explodes, oxygen ignites.
Does terminology really matter when you've burnt of your eye brows?
It does since oxygen isn't combustible. Hydrogen is. Oxygen helps burn things, hydrogen explodes.
I solder to stainless fittings to kegs for brewing all the time. Use Harris Stay Brite #8 solder, Harris Stay Clean Liquid Flux, and keep it VERY clean with some surface abrasion to get through the passivated layer. Cleanliness is very important (much more than Cu soldering) and the Harris products are high silver content compared to regular solder. But if your parts are clean and you use the harris stuff, it solders even easier than copper because to lower thermal conductivity keeps the heat where you want it and you can walk it around. It's easier to overheat stainess soldering than copper though for that reason too.
Liquid O3 !!!! =}
please?
Wow, thats my favorite intro yet!
Hi random person scrolling through the comments
Serge Biln hello my dude
Serge Biln hello
Great work Cody!
When your a real nerd "a insulated drinking flask" instead of thermos. Grant Thompson beat that!
I'm kind of feeling Cody's going to build a warp drive eventually from pipes, nitrogen cooling, electricity, and old microwave, magnet array and some disco lights.
Nice one butt. Enjoy your inventions and video productions 👍
I want to be first so I am going to rush this comment
Porter Christenson you failed
YOU'RE TOO SLOW!
It is actually extremely easy to silver solder/braze stainless steel with BAG24 silver solder and white flux. I have made Stirling engines using stainless steel water bottles in this way. I have braised or soldered most metal combinations including aluminum to stainless steel and honestly stainless steel with BAG-24 was probably the easiest to do other then copper.
