A malleable play material binder is combined with a substantially greater quantity of sand to form a granular malleable amorphous play material having an unusual tactile characteristic. The play material binder may comprise a conventional play material. In the preferred embodiment, the play material binder is formed by mixing a soluble cellulose, a polyvinyl alcohol, propylene glycol, water, sodium tetraborate, sodium carbonate and a light mineral oil.
