You might be thinking that it’s difficult to get fresh water out of salt water.
Illustrated below is a simple experiment to meet above mentioned objective.
Material Required:
A Glass bowl
A spoonful of table salt
A glass
A plastic wrap
Water
Small pebble
Process:
Take a bowl and fill it with water. Mix a spoonful of table salt into it and stir well to dissolve the salt.
After mixing the salt, put a small empty glass (or cup) inside the bowl, in such a way that salt water doesn’t get inside it.
Cover the bowl with the plastic wrap. Also put a small pebble in the middle of the plastic wrap, to make it slant right above the empty glass.
Keep the whole system under the sun for a few hours.
Results
In an hour, you can see water droplets on the underside of the plastic wrap.
After a few hours, you can see a little water inside the glass. The water inside the small glass is fresh.
Do you still think it’s difficult to get fresh water out of salt water?
