In this instructable I will show you how to get clean, purified water easily for free from any liquids/plants in survival situations.

The process works by having a small empty cup/box like container inside a large cup/box-like container with a piece of nylon/plastic bag sealing the top of both (one piece). A rock or some other kind of weight is then placed on top of the center of the cover to form a slope. The containers are then placed outside in a sunny area, and the water from the large container evaporates, leaving the dirt and other pollutants on the container. The water vapor then condenses on the cover to form 100% pure water drops that slowly go down the slope and drop into the smaller container.

Step 1: Choosing Your Containers

Here's what you will need for this project:

1. A large container with a flat bottom (the darker the color the quicker the process will take)

2. A smaller container with a flat bottom (it's better to use a clear container for this one)

3. A piece of clear flexible plastic (Best to use a plastic wrap)

4. Some kind of a weight (A rock works great)

Step 2: Putting Everything Together

1. Take the small container and put it in the large one.

2. Put your dirty water/plants/urine in the large container WITHOUT IT GETTING INSIDE THE SMALLER CONTAINER.

3. Completely seal the top of the large container with the piece of plastic. Use tape if necessary. You don't want the vapor to exit the container so make sure it is sealed.

4. Take the weight and put it on the center of the cover. You can carefully push on it to steepen the slope.

Step 3: Start Purifying...

For this demonstration used water with yellow food coloring (I should've probably used blue instead).

To start the process carefully take your container and place it outside (in a sunny spot).

In about an hour you will start seeing drops of water form on the cover. If the slope of the cover isn't steep enough, you can carefully tap on the drops to make them slide inwards and then drop into the smaller container.

This process may not be very quick, but it provides 100% clean water. It also extracts water from organic compounds such as plants or even wet soil.

Step 4: Summary

This is a great easy way to purify and extract water. It can be used in nature and in other survival situations as it is very simple to do and requires very little components.

I've included a photo I took yesterday of the supermoon (once in 30 years!) with my telescope.

Hope y'all enjoy!

<p>Thanks for sharing :) It's also good to note that it's not safe until you boil it as many bacteria can still survive this process.</p>
<p>Thanks. I didn't know that!</p>
I've heard about this method several times over the years but don't remember anyone addressing bacteria. After a little digging I found a fairly convincing source that shows bacteria, viruses, etc. can be killed by 6 hours exposure to direct sunlight: http://www.sodis.ch/methode/index_EN
<p>According to Google, in order to kill salmonella you need temperatures of over 148&deg;F. I don't think direct sunlight will get water that hot.</p>
<p>If you're in a situation where water can be boiled, that's ideal but I was interested in how effective this evaporation method is in more of a bare-bones survival situation (using UV / sunlight, not heat). </p><p>Here is a 2004 study from the Journal of microbiology: <a href="http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2672.2004.02335.x/pdf"> http://onlinelibrary.wiley.com/doi/10.1111/j.1365...</a></p><p>The specifics are noted in the paper but the conclusion is: &quot;Exposure to sunlight results in a significant decrease in numbers of Salmonella.&quot; It doesn't appear to kill 100%, but Sunlight has a substantial effect on Salmonella.</p>
Really nice picture of the moon! Good idea too
<p>Thanks!</p>
<p>Is that really your urine. (Gary)</p>
<p>Boi I said &quot;food coloring&quot;</p>
<p>Ok. Cool.</p>
<p>nice idea. And cool pic with ur telescope. How did u take the picture?</p>
<p>I used an adapter I got from amazon. I works very well.</p>
