I don't think the building of a liquid Nitrogen plant is a job for the amateur, If you only want a small quantity it is far better to buy it but if you need lots there are industrial plants on the market such as below.

The poll makes no sense, but people seem to like voting anyway.
I think that what you need to make liquid nitrogen is money.
Please disregard all previous signatures.

I can't decide!
I got annoyed with looking

funny that the vote is not 50/50. What does that say about us? [:P]
