fresh water from salt water

We had an experiment in our science book that the kids found fascinating. You mix salt and water and pour into a bowl of sand. Work a clean cup or other container down into the wet sand and cover the whole bowl with plastic wrap and secure it with a rubber band. Place 2-3 marbles on top over the clean container and place the bowl in a very warm place (like the sun). When you check it again in a couple hours, there will be water in the clean cup and it will be fresh water, not salty.

This is a great way to teach about the water cycle.
