It turns out LN2 is cheap and easy to get, but a Dewar flask costs around $400. I haven't been able to find a place to rent one.

- Asmodeus 17y agoAsk for a thermos instead of a Dewar Flask. They're the exact same technology, but the term 'Dewar Flask' implies a much higher grade. Remember not to seal the thing airtight unless you're trying to build a bomb.
