If you live near enough to an ocean that you can get some ocean water and bring it home with you, then you can try out this experiment to see how much salt is actually in there!
All you need to do is collect a cup of salty ocean water. If you don’t live near an ocean, you can make your own salty water by just adding a few teaspoons of salt to a cup of tap water.
Leave the cup of salty water on a sunny windowsill for a few days until it evaporates and all of the water is gone.
What do you find in the bottom of the cup when all of the water is gone?
…Salt!
