The Accidental Invention of the Slinky

The video narrates the origin story of the Slinky toy. During World War II, naval engineer Richard James accidentally knocked a spring off a shelf; instead of simply falling, the spring “walked” across the floor, sparking James’s idea for a children’s toy. He showed the spring to his wife, who named it “Slinky” for its sleek, graceful motion. James borrowed $500, produced 400 units, but none sold until he arranged a live demonstration at a Philadelphia department store. The demo, featuring an inclined plane that let the Slinky tumble down, sold all 400 units within 90 minutes. The product then exploded in popularity, eventually reaching sales of over 300 million units worldwide. A brief interjection from a second speaker encourages listeners to buy a Slinky.
