Army rations rehydrated by urine
Would you eat food cooked in your own urine? Food scientists working for the US military have developed a dried food ration that troops can hydrate by adding the filthiest of muddy swamp water or even peeing on it.
The ration comes in a pouch containing a filter that removes 99.9 per cent of bacteria and most toxic chemicals from the water used to rehydrate it, according to the Combat Feeding Directorate
