    I found these drink bags on ebay a while ago and have been testing them with the idea of using them as bladders. so to convert one into a bladder i have drilled a hole in the lid and glued in a hose fitting but you could use some brass tube. just out of curiosity, i connected it to a little geared water pump and started filling. I wanted to know when and where it would burst but surprisingly the pump stalled out and the bag is solid with no leaks. even squeezing it as hard as I could with both hands i couldn't burst it.

    you can also get much bigger version with a hose fitting already connected.
