I love Steve's videos! I have misophonia but I don't care: I watch his videos anyway. That man's gut microbiome must be at least half botulism by now. 😂
FWIW, I've also tried the emergency ration food bars (not the same ones that were in the prefab kit you linked to, but I've tried some others). If you're looking to use them up after you bust them open, I use them in places where I'd usually use oats or granola. Like on yogurt. They're not bad, per se, but they're not the same as a can of sardines with a pull-top. Sardines? Now that's apocalypse luxury! 😂
BTW, these are the water containers I use (I even have the 17 oz one for work). I bought the uninsulated ones because they're single-walled stainless steel so won't explode if you put them on a fire (have boiled water in them over a fire; can confirm that I and the bottles are still unexploded) and they don't impart flavour to the water (no cheap steel here). They also come with convenient carabiners for easy external storage. Just in case you (or anyone else) is ever in the market again.
