Not had a chance to look at the images yet Karen, but you dont really want to mess with liquid nitrogen - it's something like -196 degC and you certainly dont want to spill any. I remember A-Level Physics and the teacher spilling a small amount on the table - which promptly split!
You could probably buy it from any serious pharmaceutical outlet - wholesale that is - but I would imagine it's controlled/licensed in some way...
There are always two people in every picture: the photographer and the viewer
