Thanks for your replies, guys. I'll take these comments to heart. I do have a bottle of Potable Aqua tablets that I take backpacking, and have been wanting to transfer it to a smaller glass vial as offered from one of the vendors associated with ETS to make it fit in my tin. What I'm wondering is, how do you actually get more than a few ounces of water into an unlubed condom? It seems like with just holding the end open and pouring water in, the elasticity would overcome the weight of the water. I have some Reynold's oven roasting bags that I take backpacking, so maybe I'll fold one of those up in the tin for an emergency water container.
