Play-Doh is a modelling compound that has been sold as children's toy around the world for over half century. It was invented by Noah McVicker and Joseph McVicker in 1956. One of many common products invented by accident, it was meant as a wallpaper cleaner. The first Play-Doh Compound came only in an off-white, 1.5 pound can. By 1957, there were three additional colours of Play-Doh: yellow, red, and blue.
Play-Doh is available in several different colours and has a distinctive smell and texture. Over 900 million pounds have been sold so far. The product is now owned by American toy giant Hasbro. Believe it or not, the United States has even established a national day for Play-Doh.
