There’s a large chance you’ve learned about salt water the hard way: by drinking it. That swimming trip was draining you and you probably figured it would be fine to take a gulp of the ocean. To your shock, you just ended up thirstier.
Imagine being able to turn all that saltwater into potable drinking water. That would solve a lot of problems.Andy Quitmeyer harnesses the sun, salt water and some other interesting items to create a solar still.
How can seawater from the oceans be turned into fresh water that is suitable for people to drink? Through a process called solar desalination! In this science project, you will make a solar desalination apparatus using readily available materials, and a power source that is free.
How much water can the device produce, and is it still salty at all? What factors affect how effectively saltwater is turned into fresh water?
