How do self-heating hot pots work? 

This is honestly genius. Better than me forgetting water in my maruchan ramen and destroying microwaves.

Until someone thinks its the seasoning and mixes it into the food

Now I understand why those airport security guards got so angry when they discovered my grandma tried to bring one of those self-heating hot pots on a plane

This is basically the FRH (flameless ration heater) in military rations.

Surely cooking it with them chemicals are bad for your health

Why couldn't science be this awesome when I was in school?

Bpa’s are going crazy rn

I can’t imagine all the hydrogen gas is particularly safe lol

I once proposed to our chemistry teacher something that looks like this but then he got angry.. they don t like inquisitive smart curious geniuses. My idea was to generate electricity with other smarter ways resembling the work of a battery but in other forms

I think this is the same thing in those FRHs/Flameless Ration Heaters in MREs. Either way, I can't stop thinking of Steve's MREs whenever FRHs are mentioned.

Used to have these self heating cups full of hot chocolate. You would just push the bottom until it popped and it started to warm. I think they were discontinued but they were awesome.

Thank you for this explanation! Stuff like this is so interesting, please keep up the great content!!

I remember trying an MRE and being pretty surprised at how quickly the FRH got hot, idk why more products don't use this method

There are plenty of American MRE’s that have a similar pouch. Usually for warming up food

Good tip, bring these to hike and camping trip super good

I am curious about what's the effect of aluminium powder of food that soaked fumes on the reaction

When I was a kid at scout camp, one of my leaders was in the air force and he brought MREs to eat. After breakfast one morning, he put one of those pouches into a water bottle and pretended to throw a grenade at us in the other room. Shit was hilarious

Actually looks delicious

good emergency food eh
