Have you actually tried this? It could be bad advice to recommend this
if you're not sure it'll work. Two things that might go wrong: first,
the thermos might break immediately from thermal shock. Second, it
might break somewhere en route due to material brittleness at low
temperatures.

Good advice, although then I wonder how to ensure that it can't
spill, which you certainly don't want.
