one of the things have to do is to prop
it up it says rock or something very
specific instructions today we're going
to see what happens if we intentionally
misuse some MRE heaters
[Music]
[Applause]
guys this is an MRE heater MREs are
meals ready to eat its military or field
rations and sometimes you want them warm
and this is what you use to get it there
to bring in an expert on this subject we
have my friend Tyler who is in the
military so Tyler tell us real quick
what is an MRE and why do we want
heaters for them an MRE is a meal ready
to eat basically it is the modern field
ration for the modern warfighter in like
the Civil War and World War two you had
to carry around cans of food which were
quite heavy so the intent behind this
was for it to be lightweight provide
more calories for consumption as well as
a warm meal for comforts sake here's the
basic idea
military meals are heated up by a small
chemical reaction in a bag we want to
try and take those bags open them up see
what's inside and see what happens if we
intentionally use them wrong so these
were developed as a easy and generally
safe way to heat the meals up I read
some of the specifications for like what
they have to be and it's like it has to
be able to heat up a meal to a hundred
degrees Fahrenheit within 10 minutes and
to not pose a significant risk of fire
or something like that and so this is
the method if you've ever used those
little hand warmers where you just open
them it's full of iron powder which
reacts with air turning into iron oxide
exothermic reaction heats up it's very
similar to that but it uses water
instead of air and inside these little
packets there is a combination of iron
magnesium and salt those all combine and
have a very similar exothermic reaction
to those hand warmers it's just a little
bit faster and a little bit hotter I
think to start we're gonna look at the
proper use of one of these heaters like
eating at this meal yeah and then we'll
go to the improper use which is gonna be
a lot more fun well here we go here we
got water it shows it's got lines at the
bottom so you're just supposed to fill
it up to these lines with water and then
I think it just kind of squishes and
all the water gets all over it so yeah
you split to your meal next to the
heater and then dump some water in it so
normally I wouldn't even look at the
line I would just add a certain amount
of water from my canteen or water source
I'd say I usually start with that I
usually kind of squish the water around
that might even be too much and then all
try and seal it so it forces itself to
be unsealed and then you set it on a
rock or something so I'm just gonna add
some water to this one and I'm not gonna
add an MRE it's just gonna be I actually
think I added too much water so yours
will probably be a quicker demonstration
so as the water starts reacting and it
starts putting off heat it's not just
putting off heat it's also creating
hydrogen that's gonna take probably
another few seconds to a minute before
it actually starts doing anything but
then it's going to balloon up quite a
bit probably this is showing the
cardboards at about a hundred Fahrenheit
so definitely some heat this thing is
showing up at 150 for a second Wow so
we've now got steam is escaping out and
around the bottom here but I'm curious
honestly is this just steam or hydrogen
said I believe this is actually hydrogen
in the bag hydrogen generation oh cool
staying burned now it's burning plastic
I mean it was burning hydrogen too but
the plastic actually caught on fire so
usually what you do well it's heating is
you eat all your other snacks and treats
most of the food's gonna be fairly dry
especially these vegetable crackers
crackers fill the full cheese and stuff
like that would you like some jalapeno
cheese spread with your vegetable
graphic that looks like it may not still
be good like it's probably safe it's
just doesn't look good so the jalapeno
cheese spread might be one of the first
things to expire taste just about as
good as it normally does so we've got
some napkins guys a towelette salt gum
crushed red pepper so let's go with the
main meal and at this point I would have
finished all my snacks
and I would now for that oh my goodness
have a warm meal so for the main meal
from got Mexican style chicken stew I
just want to say I know that crazy
Russian hacker has probably tested all
these before but I haven't so Wow
delicious meatballs
I actually have too much flavoring and
not enough water here that's supposed to
be with 20 ounces of water this is only
a 16.9 so probably gonna be a little too
concentrated
I've had worse chickens - right yeah
it's just kind of like a chicken chili
kind of stuff it's spicy
[Music]
I was kind of testing very carefully to
see if it was gonna be too spicy no
that's like as you said perfect perfect
limit perfect heat alright so we're
gonna be testing out the so called
Tabasco bomb that is the source of
pranks military on military soldier on
soldier just in case it's actually
intense and we don't want to subject
ourselves to it we're gonna be doing it
in this pot but then to scale it up
because apparently we need to scale it
down and scale it up we're gonna do
several at once so we're just gonna have
some saran wrap cling film over the lid
of this pot and then we're gonna throw
like three or four of them in here
and see what they do and then maybe
carefully open it and see if it's pepper
spraying ourselves
[Music]
so while that's heating up and preparing
to teargas us all what I wanted to try
was to take all of the powder out of one
of these measure out the appropriate
amount of water and then mix it in and
see what the reaction does if it's not
in the containers okay yeah some of
these do look like they're maybe on the
verge of popping themselves open a
little bit I'm curious how potent all
right so I've measured out what should
be about the right amount of water this
is just all of the powder from one of
those I'm gonna try and pour this into
the middle to me honestly this seems
like way too much water
what is the chemicals here magnesium
iron and salt okay so don't do this
[Music]
gently gently salty chemical paste but I
am gonna go rinse up out of my mouth
54 compared to the rock that doesn't
have that 48 oh I just hit 80 84 b5
maybe we did it wrong maybe but never be
a victim or the perpetrator you never
learned
I took an entire bottle we could also
just yeah drench one in Tabasco it's
actually activating from the Tibet a
little bit water activating it with
Tabasco that's good I think we're I
think we're probably there yeah you're
right yep a little more intense now okay
it doesn't mean my eyes I breathe in
yeah and you just move off immediately
is your Sinus I can open the door it's
not like horrible you know you do you
experience like being tear gassed right
right so hold on oh we're near that
level yeah so a lot of military branches
at least I know for sure my experience
in the Army is at basic training you go
through the gas chamber
[Music]
yeah that's magnesium fire right there
partly yeah also some other stuff there
we go
grape drink isn't that fun we've got
four of the heating pads in one bag
we're just gonna seal it then we're
gonna cut a corner off of it and then
we're going to add water into it and
just see if we have one spout where all
the steam and hydrogen comes out if we
can make a good sort of mini
flamethrower and away we go Oh
[Applause]
oh that is hot
just it refills itself very quickly with
more all right there you go I think it's
starting to sew a little bit there we go
ow
okay nearly 200 not bad oh it's just
burned along the edge yeah I think it's
escaping now all right guys
MRE heaters thanks to our friend Tyler
for stopping by and sharing how they're
normally used and joining in the fun of
misusing them this whole idea was
brought to you by reddit user muffin the
bear so Thank You muffin and if there's
anything else you would like to see us
try with these MRE heaters please let us
know and maybe we'll give it a try
[Music]
comment or when you eat apple pie yes or
no what's the bestest I know what
they're heard that
no because it's nonsense guys that's it
for today but you know we've always got
more for to see hit that box up at the
top to check out our most recent video
and we'll see you the next one doctor
then
