^ Jeeze, I haven't seen a metal coffee can in years. Do the plastic ones work OK for wind-shields?
I've punched holes in the sides of steel cans, top and bottom, with a beer can opener to make a stove. Never had to actually use it, just for the excercise. Remove one end, place a Sterno or other alcohol container on a flat surface, place the punched-out can over the flame, and put your food container on top of that.
But: I'd rather use my Coleman two-burner stove with my propane tanks. Can't pack it around, strictly for in-situ use, but then again, as crippled up as I am, I ain't going to be packing anything anywhere.
Also, I keep a bunch of these in my emergency cupboard:
Lightweight (all-platic container), keep unrefrigerated for a significant portion of forever, readily available in grocery stores (as opposed to milsurp outlets) and are
edible if not
delightful just opened up and eaten cold. (Should the extreme need arise.)
And cheaper than MREs. ("Meal, Ready to Eat")
Many other meals besides spaghetti available.
ETA for MrsSmith and other boating folks: Just tested one for flotation. They float in cool tap water, ought to float in sea water pretty good, but can't test that without a 1000 mile trip. :)
