Disposable hand warmers work by the exothermic rusting or oxidizing
process of iron. They are completely harmless to the environment and
contain only natural ingredients - iron, carbon, vermiculite,
cellulose. Not sure how well they would work to warm a hummingbird
feeder since the hand warmer needs to be manipulated from time to time
to keep the dry components mixing.

>From a google...
Iron in the pouch, when exposed to oxygen, oxidizes and therefore
produces heat (aka, "Air Activated").
When iron oxidizes it produces iron oxide, more commonly referred to as rust.
Salt acts as a catalyst.
Carbon helps disperse the heat.
Vermiculite is used as an insulator for the purpose of retaining the
heat and cellulose is added as a filler.
All of these ingredients are surrounded by a polypropylene bag.
Polypropylene allows air to permeate the ingredients while holding in moisture.

I have never seen one so I do not know of what materials they are comprised. I am not asking to foment dissent within the group so please reply off-list if you know the answer to my query. Thanks.
