How can you get the salt out of salty water?
The most simple way is to boil the salty water until all the water is gone. Salt will be left behind. You can also leave the water by a window with sunlight, then wait for the water to slowly evaporate. Unless the salt was in a saturated solution, the salt crystals shouldn't be too much larger than normal.

Why is rain not salty?
Fresh rainwater Rain is a form of precipitation. When air becomes saturated with water vapor, the water precipitates out; that is, it condenses on tiny dust particles and falls to the ground in the form of droplets. The water vapor in the air got there in the first place because it evaporated, primarily from the world's oceans and seas. But when saltwater evaporates, the salt dissolved in the water is left behind, which is why rainwater is not salty. Edit: Not exactly true. SOME salt DOES evaporate (it takes a higher temperature than H2O), so rain water IS a little salty, just not so much that a person can taste it. Because only pure water can evaporate. Salt cannot evaporate. That is the reason why. Edit: Not exactly true. SOME salt DOES evaporate (it takes a higher temperature than H2O), so rain water IS salty, just not so much that a person can taste it. Rain, or atmorspheric water vapor is made of just water molecules, not anything that is in the original solution. If you boil salt water the salt remains in the pan because it is too heavy to vaporize. <a class="h2heading h2" style="color: rgb(0, 0, 0);" name="Salt doesn't evaporate">Salt doesn't evaporate</a> the salt in the sea water cannot evaporate which therefore means that, only normal water gets evaporated and turned into rain. that is why ran is not salty. Rainwater is not salty because the only thing being evaporated from the salty oceans it the water, which becomes water vapor. When it finally goes back to being a liquid, the water falls to earth as pure water with no salt. The reason is because salt doesn't evaporate. You have to picture the water cycle: precipitation, evaporation, and condensation. When water evaporates into the atmosphere, only the water evaporates. So when ocean water evaporates, for instance, only the water becomes vapor. The salt stays a solid, and remains in the ocean. Due to the process of evaporation, the salt is left behind when the water from oceans evaporate and then reform into rain drops in the atmosphere. because the water from the sea is evaporated, therefore the salt is separated from the water :) Because rainwater is fresh water, even if you evaporate saltwater the condensed evaporated water will be fresh. In the water cycle, water evaporates from oceans and leaves anything that was dissolved in it in the sea. That includes salt. When the water leaves the oceans as it becomes a gas, it leaves as pure water. All the things that were in soluition in it remain behind. Then when that water in the air hits a cold front, condenses and precipitatates out as rain, it's just "fresh water" coming down. The salt is still back in the ocean.
