OK so now I need a Dewar for liquid nitrogen.
The big ones are, like, 20 liters. So I have to fill it? Does the blade have to be 100% submerged?
Or can I half fill it and get as much of the blade in as possible. Will the cold travel? Is the air space cold enough?
Refilling liters of the stuff every 100 days is a little much for a small time maker.
