I've been having these Heaters since we were issued MRE's after Katrina and Rita in September 2005. So they're ten years, five months old in my possession, they could be older. They are the military issued ones. At 11:05 a.m. I placed one heater in a water bottle minus the cap of course. Next I emptied a Burger King salt packet followed by a small amount of water to get them wet then poured out any excess. In five minutes the bottle was too hot for me to hold in my hand. The heat lasted that strong for fifteen minutes. It is now 11:30 and the bottle is still warm. So I now know these can last twice as long as the five year shelf life I've read online. Too, fifteen minutes of high heat would definitely heat me a small meal of sorts or even can use as heating pad wrapped in cloth for aching pains or to warm me up in cold weather.  |

Thanks guys for dropping by. I corrected myself on the intense heat, it was closer to fifteen minutes than ten.  |

Good info and glad you have them. I'm glad I have them also. They do have quite a few uses. |

No, nothing special - really just the idea that people may get rid of them - while they are still usable.
With a longer shelf life than anticipated, they would be handy to have!

Well here is someone tasting 24 year old MRE's. Of course I can't vouch for his experiment but the info may still be great to know for future reference if a situation warrants us having to digest them. www.youtube.com/watch?v=1YgdMv9D82Q |

I honestly was thinking of getting rid of those I have but was gonna try out a few first to see if they'd still activate. I tried three of them and they all produced the same high heat and knew this info would probably help others here. Yep, think I'll hang on to them for a while longer. |

Thanks for that experiment sweet Cajun mamasita...I also have a bunch of those in the corner of the closet. I will try the ones I have since they are from about 2002.

I still pop in now and then.... got to disconnect from the busy schedule once in a while or you can go insane. This place is my home and lots of good people here. Hope all is well with everyone. I will be giving a crack at the MRE heater this weekend and post my findings.

new style heaters at less than $1 each (before shipping) not a bad deal
you can make your own flameless heaters
use those old blocks of magnesium and create small chips by drilling holes through it
find a rusted piece of iron and collect the rust particles (dry them out good in the microwave)
some table salt
mix 1/2 part rust, one part salt and one part magnesium chips into a pouch
when you are ready to heat add 2 parts water to the mix and seal it and your "to be heated item" together heat it up
it may take some experimentation with getting the mix right and in heating times
but it will work, I have used it.
hot hands and hot pockets contain a similar mixture but do not get hot enough, open a package and explore the quantities of material inside changing the amount of iron to magn will change the temp obtained
the salt speeds up the rusting process (chemical reaction) of the iron and adding water speeds up the "rusting/reaction" process of the magn
