Surface Tension


 Science experiment:
Surface tension


 Start out with a glass dish with milk in it.  It doesn't take much.  Just to cover the bottom of the dish.
Add several drops of food coloring to the milk.  Gently sway the milk to notice that the colors don't really go any where.  They don't blend together.  Now take 1 drop of dish soap and drop it in the center of the milk. 
 Immediately the colors spread. Creating a really neat design.  Now gently sway the milk now and see how the colors will now blend.  Pretty cool!

    We did it some time ago, and I agree, it's way cool even though the "why" part is beyond a 5 year old's grasp :) Thanks for joining Afterschool!
