Scientific Principle(s) being demonstrated: Self-clearing, usage measuring water flume device Briefly explain if the experiment was effective for you. Could it have been better?: I was blown away to find an interactive Parshall flume at this large community park on the Western slope of Colorado in Rifle. While the water was shut off for the winter, I could easily understand how this experiment would work to explore the flume. The flume is sandblasted http://www.hannasandblasting.com/Photo/Projects/pages/centennialparkrifle11.php with text explaining the features of the flume that make it work so effectively. When is the apparatus/experiment available to the public: Spring (after frost) to Fall (before frost); hours vary by day - visit http://www.rifleco.org/index.aspx?NID=93 for hours.
