>>790346Thanks for the tips, I think I'll make use of both of them. The tin can lid seems obvious, but didn't even occur to me.
Last pic of me making coffee on a hot morning under a huge abandoned railroad trestle that spans the mighty Columbia River in Washington. I used charcoal from burnt railroad ties with a tiny wad of toilet paper for fuel.
This thing heated water for a cup of coffee in minutes, probably faster than my elecrtic stove and kettle at home, much more fun to use too.
