Experiment Shows What Happens When Salt Water Is Boiled

Everyone knows that ocean water contains salt, but what would happen if you boiled it? Get ready to find out.
Science lover and YouTuber King of Random, a.k.a. Grant Thompson, decided to solve this mystery while visiting the Pacific Ocean along Oregon's shoreline. Would the salt dissolve? Evaporate? Would it congeal?
Because the ocean is comprised of only 3.5 percent salt, if you were to take one cubic mile of salt water and let the water evaporate, you'd still have 120 million tons of sea salt. So could you really get a mountain of sea salt after boiling off the water?
Grant and his wife gathered up ocean water in a big jug totaling eight to 10 pounds, which by all calculations would have approximately 130 grams of salt in it. Then, they allowed the jug to sit for a few days so that the impurities -- namely sand -- would settle to the bottom of the jug.
Once the sand separated, the salt water was transferred to another jug. Then the jug sat for 10 months on a shelf.
When Grant was ready to resume the project, he boiled the salt water for 1.5 hours until the water was completely absent. Left behind was a white residue coating the sides and bottom that is ...drum roll please ... sea salt!
The powdery substance was easily extracted from the pot. It's truly impressive to see how it's left behind when the ocean water is boiled. Who knew?
After Grant weighed the substance, he processed it in a blender and poured it into a glass salt shaker (so he could use it later on his popcorn, of course). Then the King of Random evaluated the final product with a taste-test. He was a happy camper!
It's incredible how this very cool scientific process takes you from a glistening jug of sea water to a powdery white pile of sea salt. You'll be amazed and may want to try it yourself! After all, it takes the phrase "fresh from the sea" to a whole new level.
