Advice: Make your own water filled Heavy Bag

[fcvp]

I am looking to convert my heavy bag from filled (with old clothes) to water filled. I cannot find a bladder for sale anywhere so I thought I'd make my own. However I don't know where to start.

Anyone ever done this before? Any suggestions on materials or process?

Thanks

Sounds like you might be better off just buying a water bag.

I used an elephant bladder from africa. kinda smelled but holds up nice. Amazon Africa has them for only 2 ivory tusks.
