History:
One day in 1943, USA naval Engineer Clay Watson (Clay Watson) in a shipyard and colleague Richard James is in the Philadelphia Experiment, seismic waves in the spring of the precision instruments. In the experiment of Richard James accidentally knocked a spring on the shelf, and watched it arc from the shelf a step by step to "go". Found a fall on the ground of spring was actually "walk". So he will be the only spring to his wife Betty, asked if she could dig something out. He said, as long as a suitable and proper tension of the spring steel, can produce can "walk" to the spring. Two people immediately think of it can be used to make toys.
Abstract:
The Slinkies can say is make known to every family. The most characteristic of the play is put on the stairs, down the stairs at one end with gently in the direction of the pull spring coil, then toys will naturally be stretched, drop to the next step on the stairs, shrink again, so repeated until the end of the last step.
