Today I came across a neat experiment as I was browsing through an old Highlights magazine in a second hand store. My oldest daughter decided  to try it out as soon as we got home.

Take one tablespoon of cooking oil and add two drops red food coloring and two drops blue food coloring. Stir until there are drops of color spread throughout the oil. Pour this into a clear glass which has been filled with water and watch what happens. Why does it do this?

It was really neat to watch the color separate itself from the oil and descend into the water. And in the end  the water turned . . . PURPLE!
