The pitch

It's Slinky! It's Slinky! For fun it's a wonderful toy. Watch it walk down the stairs, alone or in pairs, and see how it stretches and springs back like magic. No batteries, no fuss, just a coil of steel that keeps kids staring at the staircase for hours.

Why people remember it

  • The "Slinky" song was short, loud, and impossible to forget after one Saturday morning.
  • It looked like junk science until it actually stepped down a staircase.
  • Grandparents kept buying them because they never needed batteries or cleanup.
