Introduction: Saltwater/Dirtywater to Freshwater Converter

About: I am cool and so are you.

This ingenious invention is very useful. Using only 2 plastic water bottles and a ceramic bottle, it keeps someone alive when out in the wild using only the sun. Using the concept of evaporation and the condensation, it can effectively turn dirty or salty water pure again. Whether at the beach or in a muddy swamp, this invention can turn your water pure again. Let's get started!

Step 1: Materials

  • Plastic water bottle (16.9 oz)
  • Smaller plastic water bottle. (8 oz)
  • Popsicle sticks (In survival situations twigs)
  • Regular ceramic or glass cup

That's all you need. Surprising that so little can keep someone alive!

Step 2: Cutting the Water Bottles

Measure the halfway point of your water bottle and cut it completely in half. For the normal 16.9 oz cups, its 4 inches. Make sure there are no sharp edges and make sure you remove any paper labels.

Step 3: Popsicle Sticks

Cut the popsicle stick exactly in half and use tape to secure it to the sides of the cut water bottle. Make sure that these popsicle sticks are at least to the half-way point of the small water bottle. Also, make sure that the flat end of the popsicle sticks is sticking out. If this doesn't make sense, the pictures above will help.

Step 4: Putting Everything Together

Place the contraption that you just made over the small water bottle so that it is directly over the small water bottle. Then, place the whole thing into the mug or container you have to hold the water.

Step 5: Final Product

The video above should explain how to fill the water, but basically, what you do is fill the small water bottle with dirty/salty water and place the bigger water bottle over it and then put everything in the bottle you will drink out of.

    If you put this in the final drinking container, how do you keep from contaminating the water in the drinking container of you have dirty water on the outside of the container holding the dirty water?

    Sorry, I didn't make this very clear in the beginning. Basically, you put dirty water in the small water bottle and and nothing in the mug. The big water bottle is there to catch the condensation and let it drop down. Hope this makes it clear. if not, look at the video. Tell me if this still doesn't make sense.

    so the birty water is in the inseide of the container not the outside..

    The salt water goes in the smaller plastic bottle, sorry, I was working on that section still. Now its up there....... :D

    I would like to see the video of this in action. Any idea of how much volume per day you can process with this?

    I'm also going to add a section on how it all works.

    Yes, I am working on it. I am not home right now but the converter is at home and working. I have tried it 3 times already and I'd say the volume per day would be 1/2 a cup. it's not-a-lot, but multiple ones could really help in a survival situation. btw there is a time lapse stuck right in front of the converter, just have to go home and check. And I can't drive there because my parents are buying a car still. lol Thanks for the feedback
