No glue. No tape. Just physics! AP Physics students in Mrs. Jessica Duke’s class took on the Pringle Ring Challenge, using only a can of Pringles and their problem-solving skills to build a free-standing ring measuring 12 centimeters in diameter. Along the way, students put geometry, static friction, gravity, and structural equilibrium to the test, turning a familiar snack into a hands-on lesson in physics, engineering, and creative thinking.
