Bikepacking - a viable alternative to racks & panniers

That one would probably burn longer/use more fuel than mine.
If you're only heating water or instant stuff for one or two it might be overkill.
That's the thing with diy unsealable stoves; you have to either measure your fuel carefully or not mind burning off the excess.

Sure, though I do like the idea of eating a boily meal whilst sipping from the can I'd be making the next stove from...think of it as a 'beer can cycle' not quite the carbon cycle, but it would have its place in classrooms one day...;)
