    this isn't water filtering... it's distillation :(

    Very cool! I have tried this before, and it is very effective during the summer months. You can also drink your urine this way. And you can put a plastic bag over the leaves of a tree and when water evaporates from the leaves (transpiration) you can get a bit of clean water. Please change the title, because this is a still not a filter.

    Not just saltwater either. Other sources of water can be re-used with this.

    Good, but as they said, it is NOT A FILTER!

    Xrovevansx is right, it is a still and if you make the one that survivor man made using a hole instead of a bowl, you can procure up to two pints of water a day If you want to make it a little easier, add a straw from some surgical tubing so you don't have to disassemble it every time you want to get water from it. This will make it a lot easier and less frustrating, especially if you are in a real survival situation. I have actually have used this method and it is very effective.

    this is not a filter, it is a still.

    This is really useful, I first saw it on Survivor Man. Luckily I haven't had to use it.
