Edible Finger Paint

Clays and doughs
Clays and doughs can be divided into two groups, those that dry and those that do not dry. A clay or dough that dries will retain its shape and can be used for permanent projects (e.g., artwork, gifts). A clay or dough that does not dry may not keep its shape if disturbed, so it should only be used for temporary projects (e.g., a primary-age child could use "silly stuff to form letters of the alphabet).
