I thought this was interesting .
Meals and coffee in a can . ????? ...................... activating a button on the can , release's a partitioned chemical heat , heating the coffee or tucker .
Might come in handy for us lazy hikers who couldnt be bothered taking a gas cooker etc .
I know it's probably more related to another thread of yours but one of these suckers would be a nice little treat for your hairy mate , be careful leaving the sausage and bean concotion , it dosn't bear thinking about what damage a 7ft hairy beast with a bad gas problem could do to one's nostrills PHEWWW !!!
