so i was nursing a cold with warm Tang. and i got to thinking how Tang is suppoed to be what the astronauts drink. then i remember some thing i watched on tv about how NASA had worked on some machine that can reycle urine into clean drinking water.
My country (Singapore) actually has to do something similar to that because it doesn't have natural resources. They call it "NeWater", and it's mixed at a low percentage (right now, at least) with water bought from neighbouring countries such as Malaysia.
You know there's this thing about how people in the desert dig up frogs and squeeze them so they pee into their mouths so as to not die of dehydration. The question is "Would you drink frog piss to save your self?"
