Centripetal Force Bottles

This experiment consists of two water filled bottles containing golf balls sitting on a rotating platform. The orange golf balls are hollow and float while the blue golf balls are solid and sink. Each ball is attached by a thread to either the top or the bottom of the jar. When the apparatus is rotated the orange balls tilt in toward the center of rotation and the blue balls tilt outwards away from the centerof rotation.
