A Slinky is a toy made of a metal or plastic coil that can "walk" down stairs or move in a wave-like motion when placed on a surface. It was invented in the 1940s and became popular for its simple yet entertaining action. To play, one holds the Slinky at the top of a set of stairs and lets it go, watching as it moves from step to step. It can also be made to "walk" from hand to hand by tilting the toy back and forth. The Slinky is a fun toy that demonstrates basic principles of physics, such as motion and gravity.
