Composed of flour, water, salt, boric acid, and silicone oil, the product was first manufactured in Cincinnati, Ohio, as a wallpaper cleaner in the 1930s. When a classroom of children began using the wallpaper cleaner as a modeling compound, the product was reworked and marketed to Cincinnati schools in the mid-1950s. Play-Doh was demonstrated at an educational convention in 1956 and prominent department stores opened retail accounts.
