Here are two quick and easy recipes to make modeling material for the kids to play with. Each takes about a half hour to make, costs very little and will keep them entertained for several days.
Goop- You will need 2 cups of liquid white glue (such as Elmers) and 1 cup of liquid starch (found in the laundry section of your supermarket-usually blue in color)
Mix the two ingredients together in a saucepan, stirring constantly, until a soft dough forms. Food coloring can be added if desired. Remove from heat and let cool until it is comfortable enough to handle. Knead in a zipper plastic bag until it is smooth and elastic, similar to puddy. Store in air tight container or zipper plastic bag.
Kid's Dough- You will need 2 cups of all purpose flour, 2 tablespoons of cream of tartar, 1/2 cup of salt, 2 cups of water, 2 tablespoons canola oil and food coloring.
Combine dry ingredients in a saucepan. Add the water and oil, cooking and stirring until a ball forms. Cool until comfortable enough to handle. Divide dough and knead in plastic bag with desired food coloring. Store in air tight container or zipper plastic bag.
