MAKING A WATERSPOUT Fill a glass jar three-quarters full of water. Place a lid on the jar. Hold the jar in both hands, move it rapidly in a circular motion, then suddenly stop. You will see a cyclonic water current that tapers downward like a funnel. What you are seeing is analogous to a water- spout, a rotating, funnel-shaped column of whirling winds and water extending upward from an ocean or other large body of water. It may or may not make a difference if you put a few drops of food coloring into the water (don't stir) before "circu- lating" it. You might want to put one blade of grass into the water before making the funnel. No, I don't know what will happen. Either something or nothing; but it won't make the world come to an abrupt halt. Scientists haven't learned stuff without trying ideas. Even if the idea fails, it teaches us something.  Any problems with this page? Send URL to
