The girls were in the mood to do some science projects the other day. So we went at it :)
The first one we filled up a glass 3/4 of the way with water. Then we added an inch or so of oil. They learned that oil and water do not mix. Then we added 3 or 4 tbls of salt. When the salt was added, it pulled some of the oil to the bottom of the glass. Little by little, the salt would dissolve in the water and bubbles of oil would then rise back to the surface. Super cool to watch!
As the oil came back up, it pulled some salt with it as well...
We had so much fun!
