where did the fidget spinner trend come from
Fidget spinner The toy has been promoted as helping people who have trouble focusing or those who fidget by relieving nervous energy or psychological stress. There are claims that a fidget spinner can help calm people down who suffer from anxiety and other neurological disorders like ADHD and autism.[1] However, as of May 2017, there is no scientific evidence that they are effective as a treatment for autism or ADHD.[2][3]
Rotary dial The first patent for a rotary dial was granted to Almon Brown Strowger (November 29, 1892) as U.S. Patent 486,909, but the commonly known form with holes in the finger wheel was not introduced until ca. 1904.[citation needed] While used in telephone systems of the independent telephone companies, rotary dial service in the Bell System in the United States was not common until the introduction of the Western Electric model 50AL in 1919.[1]
