Slinky

A Slinky is a coil-shaped toy, invented by Naval engineer Richard James and his wife, Betty James. Slinkys come in various sizes, but are usually no larger than a grown adult's fist when compressed. The shape is a simple spiral, or coil design, of a ribbon of material, originally metal. The Slinky is famous for its ability to "walk" down stairs as the coils stretch and reform as gravity moves them down each step.
