This video shows various experiments with circular motion. In Dr. Carlson's Science theater he uses water, a lit candle, and a piece of paper to show the ways that circular motion causes gravitational pull. The water in a glass doesn't spill as it is spun around 360 degrees in a circle, even upside down. The flame on the candle was pulled toward the center when spun around. The piece of paper becomes a paper saw and was able to cut wood when spun. He not only demonstrates centrifugal force with each experiment, but explains how and why it works the way it does.
