When I say, “Liquid Nitrogen,” is your first response:

A) Cool stuff you can freeze things in, or

B) A royal pain in the ass.

I was ruminating on the subject while filling my diffusion pump (of course done while wearing a face shield, spash guard, cryogenic gloves, and not carrying the dewer on my shoulder sloshing it all over myself. Safety first.). I think it is kind of interesting how liquid nitrogen goes from being this magical and amazing liquid pulled out at chemistry demonstations, to a hassle that means coming in 2 hours earlier than usual refill a detector.
