all right so I'm here right now with the king of random and probably one of the coolest shop I've ever seen what's up guys welcome to my laboratory hi for real that's exactly what it is the death of phenomenal it's got so many power tools but there's one special thing that I want to show you and it blew my mind when I saw for the first time nobody knows about this yet this is kind of like behind-the-scenes top-secret pre video video okay so liquid nitrogen why do you need it what do you need liquid nitrogen well why do I need liquid nitrogen or why does the world need liquid nitrogen you particularly in particular I like the liquid nitrogen just for playing around it's fun to play with because it can make things explode it can make things freeze it's one of those substances where it has properties that you don't typically find in normal everyday living because it's so cold and the the amount of energy that it takes to make it that cold it's not readily accessible not very many people know where to find liquid nitrogen and so it's just one of those cool things it's also very dangerous because freeze your hands up again it can kill you so I'm very much intrigued by things that could possibly kill you which is weird because it can kill you it could freeze your hands off but here we are in the basement of the king of randa's house so show us how nobody needs to know that show us how you make liquid nitrogen okay I'm going to run you very very briefly through the process of how I'm making liquid nitrogen right now and if you listen very very carefully you can hear a tinking noise in the background clunk clunk clunk clunk let me show what that noise is and over here this is what we were done today means that you're going to see this popping up in my town but we had been playing with brain dummy brains coming through this is a spare room that I set up it used to be a guest bedroom now I use it for my radiator which is right down here now this is basically just a giant glorified radiator that I built with a friend of mine named Chris yep radiator here we have water pumping and through it it's being cooled by a diet first fan it's pumping air on the back the air getting stuck in here cools the water down and blows out here and I put a little extra garden like this carries in the top defenders off we have a window open because this thing is really hot and it circulates all the air flow Virginia's been bringing in the hot water cooling it down pumping that hot air off and then sending back cold water what I'm not doing that and here's what we have making that thinking noise this is a cryocooler powered by helium I'll tell you about our second do this little thing bumping up and down that's very important now this is a really good setup at that moment right now it is what we have to work with this is my nitrogen generator my name is Hank and this thing here is called the helium compressor that was pumping helium for the cryo head in fact this is the stuff because it's really really odd this is the stuff first nitrogen in liquid nitrogen so our atmosphere we're living it is about 79% nitrogen the nitrogen is all around us when this little machine here does take the nitrogen out of the air it holds the oxygen out of it and then Queensland's is a nice dry gas right eye to that point we pump it into this tank where I can pressurize it hold the tank full of nitrogen now I have a little regulator on here when this regulator just allows me to pump that gas out at about 1 psi to travel to this poly tube which runs over to the Dewar and just killing this together I'm very very close that's a few GC right here now the second system is this where the water in the radiator come in I have a helium compressor here they compresses helium and you as a gas compressor keeps up will that cool down we run that helium over to the trial head and the whole purpose of the cryo head is to pump the gas in there and then rapidly expand it and as it expands it gets very very cold and some heat out of the Dewar the hot helium gas run out of the human compressor whereas liquid cools with water pumping out water back up to the radiator to cool it back down so you can come back down repeat the process so this thing right here is just a glorified conditioner to get so cold when you put nitrogen gas on doing it condenses and starts dripping down in the sewers and so with all the system in place how long would it take for this system to fill up with liquid nitrogen so you got to think we're just putting it in one drop at a time so this is a 35 litre Dewar it's going to take about 2 to 3 weeks per cell completely but we've already got about this means bond how much do we have I think they were half full right now it's probably somewhere around 20 liters and a building up completely would cost me about 170 dollars so making it a home I don't know it really saves a whole lot of money but who else is making liquid nitrogen at home I think it's cool lava so you pretty much have an endless supply of liquid nitrogen right yeah because we live in in nitrogen we're just cooling it down and turning into a liquid updog yeah there's nitrogen in the air that we breathe that's right in fact if I just let it running if I let this thing just keep running without the nitrogen generator I would basically just be making a liquid liquid atmosphere which would be a nitrogen and oxygen and I can use this liquid nitrogen to make liquid oxygen basically make any kind of variety of gases or liquids that we want just really effective and it's great for cooling things down quickly that's interesting you also mention that there's helium inside of that machine so is the helium ever used up like you have to replenish that or is the system completely like self-sustained good question now the helium compressor is a closed system so all it's doing is it's taking that helium it's compressing it and then it's going through a heat exchanger to cool that gas down then it's running out for the cryo head where it expends and heats up again and then runs back in just repeats that process it's just exchanging cute let just like your air-conditioning unit does in your house this is just on a much higher level and a lot more expensive so as long as it has an electricity it can keep making liquid nitrogen forever yep as long as there are no leaks in the helium compressor that healing will stay in there in a closed-loop system indefinitely that's impressive it's also impressive that he jerry-rigged that whole system right here in his basement that all came from three years of trying to find parts and piece them together from university surplus eBay Amazon all over the place so we finally got working this is my second back batch of liquid nitrogen the first bath I used to freeze a heart in one channel and we smashed it and we kind of dissected a heart with liquid nitrogen so another abnormal use for it that's how I roll and I will actually have a full tutorial on this liquid nitrogen generator going into a little bit more depth of how it works on my channel in the near future so going to come check me out came around on one with you nice cool contest for you thanks for giving us a behind-the-scenes look I was very very impressed but you guys channel leave a link in the video description below and right up here in this section I'll show you what we've been working on here on his counter thanks step for watching I'll see you around
