A retired Navy Engineer, Richard James, noticed a problem while he worked at the Philadelphia Naval Shipyard toward the end of World War II. In this way, it mirrors the Slinky itself. It’s a brilliant demonstration of high-level physics concepts like kinetic energy, gravity, and the impact of momentum.
