Out of curiosity ... how does one purchase LN2 as a commodity? If I walk
into the local AirGas outlet, I need (1) a business license, (2) a physical
bricks & mortar address, and (3) a proper dewar. Not a common household

Subject: [DCHAS-L] Liquid nitrogen in the kitchen
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.
