Play-Doh is a modeling compound similar in texture to bread dough that has been sold as a children's toy around the world for over half a century. While its exact makeup is a trade secret, it is non-toxic, non-staining, and soluble in soapy water. When kept in a sealed container, it remains pliable, but when exposed to air it hardens in about a day. Play-Doh is available in several different colors and has a distinctive smell and texture. One of many common products invented by accident (it was meant as a wallpaper cleaner), Play-Doh was invented by Noah and Joseph McVicker in 1956. The product is now owned by American toy giant Hasbro.
