Ralph,
If you are looking for a means to demonstrate the negative effects of liquid nitrogen, purposely pour some upon a pound cake and be sure to use a thermometer to demonstrate the cold.
As a teacher at Keene State, I'd imagine it's much easier for you to get vs the public, but restaurant Depot has this item in a cannister to help with manufacture of chocolate mouse.

In follow up to our discussion a week or two ago about making ice cream with liquid nitrogen, I wonder if anyone on the list has put together a briefing sheet on best safety practices associated with this activity? (Yes, we'll be hosting such an event next week.)
Google helped me find some cringe-worthy videos of this activity and a couple of culinary magazine articles that provide a quick glance at the hazards associated with liquid nitrogen in the kitchen, but I haven't found a summary of safety aspects of this innovation. Happily, I have David Katz's procedure for lN2 ice cream to start with, but am looking for something more eye-catching to remind the audience that doing this at home isn't quite as simple as it looks in the hands of an experienced chemist.
Thanks for any suggestions about this.
