First, I put a few drops of yellow food coloring in 2 yellow balloons and filled them with water. I put a few drops of blue food coloring into 2 blue balloons and filled them with water.
The girls had fun playing with the water balloons in the bath!
Then they popped the blue water balloons and loved their blue bath water!
Next, they popped the yellow balloons to make green water!
What a fun color mixing activity! Thanks to Amber B. for this great idea!
