We made egg carton caterpillars:
Mix 1 cup corn starch, 1 cup baking soda and 1 1/4 cup water in a saucepan. Cook over medium heat stirring constantly until dough forms. Make shapes and air dry til hard.
These are our leprechaun hand prints when they dry we are going to paint them green!
Mix equal parts cornstarch and water until a goo forms-
I added a little more cornstarch then water.
