In this video from DragonflyTV, Valerie and Margie compare waterslides at an amusement park to determine which is more fun. They set out to measure two factors: speed and "wildness." To calculate the speed, Margie uses a stopwatch and records the average time it takes Valerie to complete each ride. Knowing the length of each waterslide, they divide distance by time to determine average speed. To determine how "wild" each ride is, they create their own tool—a mazometer. Margie's ability to keep within the lines of the circular maze while riding the slide determines its wildness.
