How could you use what you learned to change salt water into a source of drinking water?

You can try this simple experiment to change salt water into freshwater. This is a process called "desalination." The water evaporates and leaves the salt behind, so the water you collect in your collection glass is clean drinking water. ... Add a few spoonfuls of salt to the water. Make the water as salty as you like.
