There is only one slinky toy and it has been going for over 75 years. It stretches, wiggles, walks, and it jiggles.
Now you just need a very long flight of stairs and watch it in action again and again.
Slinky
This classic metal spring toy walks downstairs, alone or in pairs, and makes a slink-ity sound. First invented by mechanical engineer Richard James in 1943 during an experiment with tension coils. James accidentally dropped a spring on the floor and watched as it began to “walk.” Two years later, he introduced his walking spring toy in Gimbels Department Store during Christmas, and the Slinky immediately sold out.
Since its debut, over 300 million Slinkys have been sold worldwide. In 2000, this classic toy was inducted into the National Toy Hall of Fame. Made 75 years ago, Slinky continues to be a favorite toy of children and adults all over the world.
