Used to use liquid nitrogen every day at work. All kinds of fun uses, not to mention the entertainment factor. It is great at dusting the floors. Splash it across the room and it all gathers up on the other side. Killed a wasp in mid flight once just by how rapidly the air temp around it dropped when I tossed a cup full up at it. It actually takes a really long time for a small orange to freeze all the way through (several minutes). Good times....

Your work sounds insanely fun. No I do not ever want to go there.

I am curious, what kind of dirt that was?

It was fun. Used to be in the optics industry building IR optical assemblies. Because we were measuring heat, the equipment has to be cooled down. When running measurement scans on lens assemblies, there can be quite a bit of wait time. The mind naturally wanders. That is when the true learning and discovery happens....when the boss is away of course.
