Libby Clements, 10, prays to "Taco Cat" for a marble to make it through the roller coaster she and her team built at Gillette's "Area 59" earlier this week. More than 80 fifth grade students from Campbell County schools took part in an exercise to design, build and test roller coasters made out of cardboard, tape and other household items. The exercise gave students an opportunity to make plans, test the plans and revise them as needed. (Photo by August Frank, Gillette News Record)
