We have been having a lot of fun with mixing colors and doing rainbow experiments lately. This one did not disappoint.
-6 clear containers
-Red, Yellow, and Blue food coloring
First begin by filling 3 cups up with water and leaving 3 empty. Next mix each color into one container each and arrange them in a circle with an empty container between each color.
Now just wait. In a few minutes you will see the colors start to creep up the paper towel. A few hours later you will see the colors make their way into the empty containers and start to mix.
When we did the experiment my almost 4 year old son was so excited every time he went into the kitchen and saw the colors moving and mixing. It really helped him remember what colors you mix to make orange, green and purple. It also gave me the opportunity to explain how sometimes you have to be patient for great things to happen.
Not to mention I was able to do something even my artist wife had never seen!
