Original Slinky

Slinky, Slinky oh what a wonderful toy!

The Slinky is a toy I had as a youngster and remember to this day. It is a precompressed helical spring invented in 1943 by Richard T. James.

He was a Naval mechanical engineer stationed at William Cramp & Sons Shipyard (which had been re-opened for WWII as Cramp Shipbuilding to build cruisers and submarines) when he accidentally knocked a spring off the table and it basically “walked” to the floor down a series of books and boxes and such.

By 1945 he had them on demo at Gimbals in Philadelphia in November and sold all 400 units. The rules that govern the mechanics of a Slinky are Hooke’s Law

(a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, Fs = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.) and the effects of gravitation.
