James Industries copper Slinky in original box, measures approximately 2-1/2" high, 3" wide and 3" in depth. Mechanical engineer Richard James invented the Slinky by accident. In 1943, he was working to devise springs that could keep sensitive ship equipment steady at sea. After accidentally knocking some samples off a shelf, he watched in amazement as they gracefully “walked” down instead of falling.
