Capillary Action Experiment
It's a trick, it's magic -- no! It's capillary action, the amazing, gravity-defying scientific phenomenon that causes liquids to flow up. How does it work? Why does it work? Wonder no more because with this simple and fun experiment, you'll see capillary action with your own eyes. You, kid scientist extraordinaire, will test the capillarity of several different straws, determing which kind of straw has the strongest capillary action.
Conduct a capillary action experiment. Does capillary action work best in narrow or wide drinking straws?
