CENTRIPETAL FORCE: BUCKET OF WATER

NARRATIVE
            This is used to demonstrate the centripetal force of the rotating bucket on the water. Fill the bucket between ¼ and  ½   full of water. Swing the bucket in a circle at an angular velocity sufficient to keep the water in the bucket. To add a little humor to the demonstration, you can fill a similar blue bucket with confetti and do a quick switch at some appropriate time. Then you can throw the contents at them, while they still believe that the bucket contains water.
