Which is what can happen over a long weekend if someone forgets to top up a cold trap and it runs dry so that only the ozone liquid remains. It is rather unstable and tends to detonate at some point as it warms up.

This guy is very inspiring making liquid air with a sterling cryo cooler
he inspired me to buy the same thing..

PS if you are in a 60 Hz country you can simply run these from a variac.
Maybe pressure swing absorption (PSA):
If you have a large basement, there's already a lot of nitrogen in there.
In the LHC, simple magnet quenches are well contained, but when an interconnection failed in 2009, some 6 tons of liquid helium were vaporized, which tossed several 40-ton magnets off their supports. You don't want to be near when that happens.

Station a satellite over the Great Red Spot, and look at the swirls in the bands approaching it and take a snapshot. No two will ever be alike.
John Larkin doesn't ever get that flattery he feels he deserves, which makes me universally disagreeable - for him.
Liquid nitrogen doesn't "turn into liquid oxygen" which would be transmutation. It condenses oxygen from the air, becoming closer to liquid air in the process.
It was a remarkably stupid thing to say, and John Larkin is compounding his original stupidity by failing to recognise how stupid it was.
"Nitrobenzene".
It's a carcinogen, so it may yet kill you.
The acetone is just there as a heat transfer medium - it only freezes at -93C.

6 tons of liquid helium sounds expensive. And deadly.

The was no one in the tunnel, so 'only' material damage. It took a year to repair everything. Expensive, definitely.
Security is pretty strict. We all carry oxygen rescue masks down there. Obviously, no one gets in while the magnets are powered. Access control uses biometry -an iris scanner- for identity confirmation, just like in the Dan Brown book. To get access, we have to fill in long forms, which are then pondered over by planners, machine specialists, security and radiation protection people. It's all very tedious. Often, the red tape takes more time than the actual job.
Myself, I've been down in the LHC only a few times, to help colleagues troubleshoot some EMC problems. I consider myself fortunate that there are no cryogenics in the machines I work on normally, so I don't need to drag along that cumbersome mask all the time. The red tape is the same though.

Larkin is an idiot. What about Helium is "deadly"?
IF you are stupid and try to "breathe" it without including oxygen.
INERT NOT explosive.
So what is your problem, wussy boy?
However, over-the-air TV does not require bulldozers, excavators, road closures and ugly cable boxes that sometimes get knocked by a drunk driver. Also no digging up grandma's rose garden to lay conduit. Most of all it does not create a captive audience that can be fleeced.

Another example of how wrong AlwaysWrong can be. Idiot indeed.

Tell us, KRWtard, just what about Helium is so "deadly"?
You are both abject idiots.
step one is to more accurately specify the load.
12pf how much resistance how much inductancethen you can determine how big of an amp you will need.

Ice jams, you idiot.
AlwaysWrong is *always* wrong. Just another example of just how stupid he is.

6 tons of Liquid Helium is NOT "ice jams". 6 tons of Liquid Helium is NOT "deadly".
Step 2 is to avoid radiation It can be impossible if the 12pF load has wide spacing between connections.
It's unbelievable just how stupid you are, AlwaysWrong.
After a couple of dozen years, it's _still_ amazing just how stupid you are.
