How to Successfully Turn Salt Water Into Drinking Water

If you find yourself in a situation in which the only water you can get your hands on is undrinkable salt water, you may be inclined to simply drink this water or throw in the towel.

Never drink salt water in any amount, and throwing in the towel is completely unnecessary when distilling this salt water into pure drinking water is a fairly straightforward process.

Evaporation Distillation Method 1

This is a simple method but won’t net much fresh water at a time. If you’re on the run or just need enough for a couple of people, it will work, though. You’ll need a metal cup heavy enough not to float or heat-resistant glass, a pot with a domed lid and heat.

Place the cup in the pot.
Add salt water to the pot, making sure that it doesn’t get in the cup. Don’t fill it so high that you run the risk of the water boiling into the cup.
Turn the lid upside down and place it on the pot. Make sure that your cup is underneath the lowest point of the lid and that the lid seals well. Otherwise, you’ll lose most of your steam before it drips into the cup as fresh water.
Turn the heat up under the pot so that the water boils gently. You don’t want it to boil so hard that it splashes salt water into the glass or upsets the glass.
As the water boils, it will turn to steam, which will rise to the lid and run down the lid into the cup, leaving salt and other impurities in the bottom of the pan.
As a side note, you can do this with a pressure cooker too, and it will require less heat. Just be sure that you don’t boil it dry and crack the cup or the pot.

For another distillation method that's just as effective, visit the next page. I hadn't thought of the this time saving method before!

    If you have time and are stationary enough. Large metal make a moonshine still. You’ll need a large metal container, k copper (bendable) make or have a 2nd large container and a container to put distilled water in. Set the large metal container on a non burn able stand (brick rock or metal) connect the copper to the top, bend the copper into a downward spiral, place inside the other container making sure the copper extends past the bottom edge of the second container, coat the bottom whole with anything to keep the water in the container. Fill the first container with water you intend to purify, fill the second with other water, light fire under the first, put bottle/canteen/jug under the exposed copper below and wait.

    Use a kettle or pressure cooker and weld a copper pipe to the spout of the kettle or make a hole in the pressure cooker and weld the copper pipe to the hole, then at the far end make a coil around a can or bottle with the copper and have a piece sticking out about a foot long, then place the copper in a metal bucket and drill a hole for the foot long piece of pipe and weld the copper to the hole so that it wont leak. Then put another hole with a tap on it in the same bucket so you can fill with cold water but let it out and fill with more cold water so the (bucket condenser) works better. There you have your own water distiller. It will work for alcohol as well but you need a temperature sensor in it and a doubler would be useful for the steam (a metal cylinder inbetween the condenser and the kettle or pressure cooker). I made one with a pressure cooker, thermometer, copper pipe and a bucket. It is in my shed but needs fixing as some of the weld has come off the pipes but it worked well.

    You gotta boil off the water so the salt stays in the po

    Wait- that’s not right.

    My guess is they’re doing that whole steam collection method, or where it leads to a tube steam goes up and drops into another’s container. Like a solar still but with fire. I Won’t know because they’re clickbait bullshit
