Delicious!

My mouth is watering at the very thought of these tasty morsels!

My favourite paragraph in the article: But Hydration Technology Inc, in Albany, Oregon, which made membrane, warned it is too coarse to filter out urea so soldiers should only use urine in an absolute emergency.

It chills my blood to think there are soldiers on the front line who actually need to be given the advice 'Don't piss on your sandwiches unless you have no other choice'.
