drinking water from salt water

This is so easy and so fun! All you need is a sunny day, 3 cups of water, 1 1/2 tblspns of table salt, saran wrap, a coffe mug, large bowl, a spoon, and a small stone or two.

First, pour 3 cups of water into a large bowl. Add 1 1/2 tblspns of table salt and mix until dissolved completely.

Place the coffe mug in the center of the bowl, in the salt water, without getting any in the mug.
Next, cover the bowl with saran wrap. I placed a rubber band around the edge of the bowl to keep it sealed tight.

Now place the stones ( I used two small stones) on the saran wrap just above the coffee mug. This creates a point for the condensation to drip into the mug! Now all you have to do is wait! It takes several hours, but comeback from time to time to watch the condensation form on the saran wrap and start dripping.

Now it's time for the taste test! We all took a sip and were amazed by the fresh, clean, unsalty water! The kids really liked doing this. We have been talking about matter and how water changes from a liquid to a gas to a solid. Science is always a hit in this house!
We have been working on the Periodic Table, after finding that great book Lisa at 5 Orange Potatoes suggested we just had to, and today we are looking at Boron. We are going to make some homemade cleaners with Borax I found on The Artful Parent. There are some great body products on her site as well. We started spring cleaning yesterday (a little late, I know) so these cleaning products will really help a lot!!!
