Liquid nitrogen is saferf probably as nitrogen is a safer gas (79-80% of the air or so), although it is really cold that you'de need gloves or something.

Hello Mr. JAGWIRE..
I believe what our friend Xatlox was referring to was the following...
in the late 70's and early 80's people used Dry ice to gain sort of a "fog" effect for dance parties, theater, live concerts,etc. it was reverentially simple in idea cause all you had to do was drop a chunk of dry ice in some water and next thing you know you had "fog".
a really cool effect but to today's technology in "fog" dry ice is dated and mostly out of use not as much for safety but of operation,costs,ease of use from other methods. the affect is pretty safe for breathing as long as the place/room has some circulating air and you don't touch the dry ice with bare hands for long..or at all.
When I was around your age and starting out in my first hobby (playing with dance lights) I tried the dry ice "fog" idea for myself. My father bought some Ohama Steaks and had them delivered to our house. when the steaks came in they were kept cool but a bag of dry ice. I grabbed the bag and dropped it in a bucket of water after my father threw the packing for the steaks away. It was cool as hell and so cheap to do really.
the major use of dry ice in theater was for the low lying ground effect of the "fog" that resulted. a lot of theater plays and what not wanted to make a scene with some fog hugging on the floor. being super cold the "fog" from dry ice would stick to the floor.
these days its easy and even cheaper to get this effect. first off anyone can find a decent fog machine for $40.00 and pick up a gallon of fog fluid. the fog from the machine will rise up in the air being the result of heat (instead of cooled like dry ice), so to keep the fog down all one has to do is take a Coleman type of cooler and cut to holes in it (one on each side) and place the outlet of the fog machine in one end and leave the other opening open. now place some regular water made ice in the modified cooler and put the top back on. when the heated fog from the machine comes in the cooler with ice it will be cooled down, thus staying or sticking to the floor...like the dry ice "fog".
oh BTW:
there are co2 machines also used in clubs,theater,etc but its just a blast of steamed effect air and quickly fades off...which is not what you would use dry ice or a fog machine type of effect for.
