I'm saving a foil CapriSun juice pouch for experimenting with as soon as possible. Have to convince the wife it's worth starting a fire to see if it can boil water without too much detriment. Has anyone tried this technique and succeeded?
I thought these were made of plastic (mylar?). Then again, on one of the survival guy cable shows, the guy showed you can boil water in a regular PET plastic bottle if you're careful about how close you get it to the fire.
I'm liking the metal Band-Aid box idea. Not much capacity but it would make a good PSK carrier and it's pocket-carry friendly. Rust would be a concern, as they are not stainless steel. Do they still make them? I can't remember seeing one in a long time.
