1945
According to Wikipedia, the slinky was first introduced in the US by Richard James between 1943 - 1945, when it first became a "hit". See: http://en.wikipedia.org/wiki/Slinky#Creation
The slinky was invented by Richard James in 1945 when he accidentally knocked over a coiled spring and saw how it "walked" down some books. Recognizing its potential as a toy, he and his wife Betty developed the idea further and introduced the slinky to the market.

The slinky has provided entertainment and inspiration for creative play. It has also been used in educational settings to demonstrate principles of physics. Additionally, the slinky has become an iconic toy that has sparked nostalgia in many people.
I think that the Slinky original is the best. It's bigger than the Slinky Jr. and will most likely go faster! BTW, I LOVE Slinky! Chow, ;)
Longitudinal wave: is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil left and right.
The length of a slinky when fully stretched out varies depending on the size of the slinky. On average, a standard slinky can stretch out to approximately 2 meters (6.6 feet) in length.
A slinky is a toy that you can play with.
