Wow, I don't want to describe this as "epic fail" but this experiment was
The chemical hand warmers sure use a lot of air. With under an hour of
experimentation, the hand warmer was completely cold and the bottle was
partially collapsed. I'd guess that all the oxygen got sucked out and
that's the 78% nitrogen I'm seeing in there. I guess this stuff would be
good for keeping food fresh, eh?
