I felt immediate happiness when the Slinky song started in this YouTube video. I had a Slinky, each of my sisters had a Slinky at some point in time. Slinky did live up to the commercial hype and could walk down the stairs. The spring was fun to hold and set into the ‘up and down’ motion. The down side, Slinky inevitably became a snarled ball of ‘precompressed helical spring.’ It’s fun to read the history behind the popular toy. The History of Slinky.
