ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************
Our touring show uses about 2litres per show (we actually use slightly
less than that, but can't re-use the dregs as they are full of petals
etc! Anyway throwing it away is part of the fun! We travel with a
25litre dewar in the van (there are a lot of regulations about this,
at least in the UK). The show lasts an hour, but the liquid nitrogen
is only used for the last 10-15 minutes. That 25litres will usually
last around 5 days.
