hmmm

well when we needed liquid nitrogen quick...we went to the aircraft servicing department at the airport. seems they use it for jet aircraft all the time.

hospitals also use liquid nitrogen. they use it to "burn" off warts.

hope this helps

Try a gas company, Brittish Oxygen company. Probably welding supply companies would have it or could tell you where to get it.

Good Luck. I bet you are a great teacher.
