Play-Doh

Play-Doh is a non-toxic compound similar in texture to bread dough that has been sold as a children's toy around the world for over half a century. Its exact makeup is a trade secret, but it is primarily a mixture of wheat flour, water, deodorized kerosene or another petroleum distillate (which provides the smooth texture), salt, a drying agent such as borax (which deters mold), an alum-based hardening agent, and colorings and perfume.^{[citation needed]}

It is non-toxic, non-staining, and soluble in soapy water. When kept in a sealed container, Play-Doh remains pliable, but when exposed to air it hardens in about a day.^{[citation needed]} However, because it tends to crack during hardening, it is not good for projects one wants to save.

Play-Doh was invented by Noah and Joseph McVicker in 1956 and awarded U.S. Patent 3,167,440 in 1965. One of many common products invented by accident, it was meant as a wallpaper cleaner, but Joseph's sister, a kindergarten teacher, started letting her students use it as a molding compound for art projects, since clay was too hard and messy. It was marketed by toy manufacturer Rainbow Crafts, and first sold at the Woodward & Lothrop department store in Washington, D.C.

Play-Doh is available in several different colors and sizes, 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.

In 2006, the distinctive Play-Doh smell was turned into a limited-edition fragrance by the Demeter Fragrance Library to celebrate the product's 50th birthday. There is also a national Play-doh Day on September 18.

While Play-Doh is registered there are many different recipes for generic play doughs with various differences, such as edibility, odor, and color.^[1]

In 1956 a cool new type of modeling clay was invented and was put in schools and stores all around the world. In 1965, Noah McVicker and Joseph McVicker came up with the name they now call “Play-Doh.” Play-Doh is now one of the most popular children toys. Over 2 billon cans were sold since it was invented in 1956. Play-Doh use two only come in one color, white in a card board can. Then Joe McVicker came up with the idea by putting it in a plastic can, because a cardboard can was to hard for children to open. After, in all school both teachers and students were playing with the fun to play with Play-Doh.
