They produce liquid air by pumping to high pressure and the releasing into a chamber - This provides vast cooling in a multi stage system to liquefy the gas.

I don't think your going to do this at home in any easy way other than buying liquid nitrogen.

The basic principles were well established 100 and odd years ago by Kammerlingh Onnes amongst others. Probably the best way to try it is to find the old papers and work from there

The easiest way at home us to buy liquid nitrogen, and use it to cool down air - when you get a blue liquid, that's liquid oxygen.
