How Do You Separate The Salt Water?

How's this: Saw the coconut in half. Fill one of the half coconut shells with sea water. Use the matches to start a fire with coconut fibre and driftwood and set the coconut shell of water on the fire (I could have a problem here...) Use the palm leaves as a cool surface on top of the coconut shell for the steam to condense on. The steam will run down the palm leaves and into your bamboo sticks which are cunningly placed to collect all the moisture in the bucket.
Well.... How should I do?

If you mean separate salt from water then do it by heating the salt water.The water will evaporate which may be collected and the salt will be left behind.

You can separate salt from a salt water solution by evaporating the water and it'll leave the salt behind

You just evaporate the water

The answer that Conceptual put is correct.

The most easiest way is crystallisation.  It is done by using the heat of the sun to evaporate the water to leave a saturated solution of salt known as brine. When the is saturated the salt begins to crystallise and it is removed using large scoops.

Salt water is sodium chloride. You can separate salt from water to extract a non-salty potable water by boiling. Allow the sediments or "salt" to settle for some minutes and slowly pour the liquid or water in a clean container leaving the "salt" behind. Let it cool...it's good water!
