in a completely sealed system, the liquid nitrogen 'evaporates' much faster than would deem desired by any serious company.
it's also exspensive to buy, hold, transport, handle and take care of liquid nitrogen. i've tried this little experament in my garage... i got to the part where i was going to buy the liquid nitrogen.
when i found somone that would deliver to residential neighborhoods, i discovered their minimum order was 30 gallons... and at $8.50 a gallon, only to be stored in a state-installed sotrage unit (which is alot more than you'd want to know) it therefore made my little experament a bust...

It's difficult to find a place to buy it and it's difficult to transport, but it's actually available _much_ cheaper than that.

No it's condenced water vapour, like fog. And it's not very dangerous unless you're daft enough to contain it in a closed vessil of some kind. It evaporates so quickly that it cannot wet the surface, it just rides around on a pillow of boiling nitrogen. It's not at all dangerous to spill a little on your hand or get a few drops of spray on you. Hell I bet you could spill a liter of it over your shirt and jeans and it would just run of onto the floor and boil away, just don't try to stick any extremities down into the liquid and whatever you do don't EVER touch anything metal that you have cooled in liquid nitrogen, metal transfers heat very quickly and does not create a cushion of boiling nitrogen keeping you away from it.
