Play-Doh is a popular modelling product for children. It is made from water, salt and wheat flour and so has a texture that is similar to that of bread dough. Although it has been sold throughout the world since the 1950s, the exact formula for the compound still remains top secret.
Brothers, Noah and Joseph McVicker, invented Play-Doh in 1956. Joseph’s sister-in-law was a teacher in Cincinnati, USA, who wanted a fun and safe alternative to clay modelling. Joseph sent her a sample of a compound that had been around since the 1930s that was used as a wallpaper cleaner. The product was a hit and so it was reworked and sold as Play-doh through a new company formed by the McVicker brothers called Rainbow Crafts. Originally Play-doh was only available in one colour and that was off-white.
