I’m guessing the personal items are fruit roll ups and fairy wings.

My wife keeps an eight foot tape measure in her purse. I’m amazed at how many times we’ve used the tape. Next time a vendor gives me one of those cheap promotional little tapes ... it’s going in my Jumbo possibles bag.

Randy,
Remember you can’t boil water (safely) in an insulated bottle. The air pressure between the two steel layers can cause it to explode when exposed to high heat.

Haha you funny guy. You make me laugh.

AND for your information I keep the fruit roll ups in their very own water proof air tight container so they don't go stale.

Well crap. I answered this and hit the wrong button and POOF, it was gone.

This bottle is only for drinking water or to use so I can soak the cooling towel in case Patty gets to hot. I keep a pathfinder 40oz canteen with the old style GI cup it fits down in. It also has the same shaped "Stove". It's all strapped to my Malaga that gets moved from vehicle to vehicle as needed.

Mine is like this without the fire starter, spork and container "Holder". Mine also has a different kit holder.

I picked up mine at Smoky Mountain Knife Works a couple three years ago.

Across the pond we made do with canteens and canteen cups. If you have a metal canteen you can heat it up as well as the cup.

USGI canteen cups are great. Super stout and wide enough at the base to be stable on less than perfect perches.

I had a WW2 era metal canteen but it was too valuable to use. Sold it to a collector.

Yeah, those plastic canteens don’t work so good.

Ray, I have seen videos of folks boiling water in a plastic water bottle. Even though I have seen it work my little Redneck brain just can't get around it working without melting.

I watched Cody Lundeen boil water in a plastic two liter bottle. It has something to do with keeping the plastic far enough way from the flame to prevent melting while the "radiant heat" makes the water boil.

At least that was my take away, but I'm just some dumb guy that designs buildings and day dreams about moving back to a farm.

YUP, he said as long as you didn't let it get in the flames, as you said let the radiant heat do the work you could boil the water without the plastic melting. Personally I would rather use a metal container. Using plastic to boil water over an open fire just seems so wrong.

I vaguely remember the techniques of using flammable containers for cooking but I never was seriously interested in them. One misstep and your container is gone. Too big of a loss in a survival situation, better to have a metal container in the first place.
