How to make a water purifier of two plastic bottles

This trick can save you in an emergency situation, if attainable proximity there is no source of clean drinking water.

The author of this knowledge of this technique would be very handy in last year's campaign on the Turkish mountains. We got into a completely uninhabited jungle and a little zaplutali. Stocks gradually dried up in bottles on top of the sun roasted in earnest. Imagine our disappointment when we got to the sole for many kilometers around the source and saw that it is simply a pool of muddy water!

All our attempts to filter or boil the turbid liquid does not lead to anything good. But you can pretty easy to get fresh water, almost perfect quality. See how easy it is done.

The water in the bottom of the bottle is heated by the sun and gradually evaporates. The vapor was fed through the tube into the upper bottle where condensation. At the exit, we have fresh water, free from all impurities and is quite suitable for drinking. Of course, this process takes time, but in extreme circumstances it is not the biggest sacrifice.

As for us, it all ended well. After a while we met in the mountains shepherd who took who himself gave us their water supplies. :)
