Our 'Liquid Nitrogen Show' uses directly and indirectly (pouring, boil off
etc) 2L. It is a 30 minute show.
We use approx 25L per week and thus could manage with one 30L dewar. However
this is heavy and so we also have a second 10L dewar which we use to
transport to our theatre. Transfering to the 10L dewar also creates loss,
especially if the 10L is ever emptied completely.

Hey all,
We're looking to get set up with liquid nitrogen for demos and had some
questions: How much do you typically use for one demonstration (and how
long is your demonstration)? Do you have a storage dewar on site; if so,
what size works best for you?
Thanks!
Charliss
