National Slinky Day

National Slinky Day is celebrated on August 30. It honors the famous and world-renowned toy—a colorful spring that can “walk.” Discovery recognized it as one of the most iconic children’s amusements of the 20th century. The Slinky became popular not only in its homeland, America, but also across Europe and Asia.

History

The Slinky was invented by Richard James, a mechanical engineer in the U.S. Navy. Around 1943–44, while experimenting with different springs, he accidentally dropped one and watched as it “walked” across the floor. Amused, Richard showed the spring’s tricks to his wife, Betty. Inspired, they began to develop it as a toy. Betty found the name “Slinky” in a Swedish dictionary, where it meant something like “sleek” or “graceful.” Richard took out a loan to produce the first batch of Slinkys in 1945, hoping to present them for Christmas. Initially, toy stores didn’t know what to do with it, but when Richard demonstrated the toy in a large department store, it sold out in just 1.5 hours! National Slinky Day is said to have been founded by Alex Brands, a toy company employee in Fairfield.
