I've already seen a reply to this that suggests use of a thermos. That's fine as
a thermos is a dewar bottle in disguise after all. BUT, don't screw the lid on
tight as you would for coffee. The vapor must be allowed to escape or dangerous
(explosive) pressures will build up. Also, I guess I would look for one with a
glass liner as being most likely to withstand the extreme cold.
