Apparently, Play-Doh triggers wheat allergies, so this product was developed as an alternative. In such tempting flavors as raspberry, grape, and root beer, now your kids can create colorful sculptures, and also have a taste.
Soy-er Dough was created by Sawyer Sparks, a student at Purdue University, to help a professor whose child had wheat allergies. While Soy-er Dough is edible, apparently is does not taste so good. Here's an alternative; Think Geek has a product called Yummy Dough, that can be molded, baked and eaten, although it is not wheat free. Yummy Dough is said to taste similar to sugar cookies.
