“Water, water, everywhere and not a drop to drink.” So says the Rime of the Ancient Mariner. I say that our friend forgot to pack his desalination still. I had been planning to make a still to purify and remove the salt from salt water for a while. A few days ago I finally pulled out some of the gear I take with me on every hike and tried making one. It worked!
As will most survival skills, the chances of you actually having to do this is slim, but knowing how to desalinate water is one of those skills that could just save your life if you do need it.
Obviously there are other ways to do this then the one I present below, but I tried to make this with only things that a regular backpacker/day hiker would carry with them.
- One container to boil water
- One container to catch water
- One tube from a hydration pack
- Tin foil
- A means to cool down the tube
- a means to boil water
If you want to do this as a kids project, it is a condensed way of showing them the water cycle.
