Joy Hutton glances at an engineering camp instructor as she and other campers build triboelectric nanogenerators made of a plastic egg, a bouncy ball coated in tape, aluminum foil and wire connecting to a small LED light. Engineering is one of the camps offered as part of Nebraska 4-H's Big Red Academic Summer Camps. Hutton is a rising first-year at Centaurus High School in Lafayette, Colorado. June 10, 2025.
