I didnt even read other people's responses, but does it need to be water? Whenever I dont have a piece or any papers and say...im in the woods backpacking or something, I break out the Swiss Army knife, find a good branch that is still strong but not alive, create a bowl, cut off one end, drill it with the thing next to the corkscrew, then cut off the other part, connect the bowl to the inside shaft, take a few dry puffs (not inhaling) and burn it a little...and walla! Ive used these for proloned periods and I like it. Wood tastes good.
