I like the idea of boiling water not only to purify it but to stave off hypothermia with a hot cup of boullion. For me at least having something to focus my mind on would help as well. The metal tin I presently use will hold just over 8 oz of water.

Troy, good point about the duct tape but I’m the type of person who just has to get into their kit periodically and fuss with it. Duct tape is just too messy for that.

Matt, that’s a good suggestion about a tobacco tin. It would not matter if the o-ring was ruined because it would be in an emergency situation anyway. I confess I’m unfamiliar with these tins so some research is in order.

Thanks for all the replies, Vince
