How to Make Homemade Silly Putty. Silly Putty is that rubbery stuff you played with as a child. You can use it to pick up images from the cartoon section of the newspaper, but the most fun comes when you bounce it, stretch it, pull it, and twist it. It never seems to keep it's shape for long because it is part liquid and part solid, depending on how you use it. Making this timeless, polymer plaything for your children will wile away a rainy afternoon, especially if you let the kids get involved in making it.
Pour 2 cups of glue into a bowl or a plastic baggie.
Slowly add 1 cup of liquid starch to the glue. A small amount of food coloring may be added, if desired.
Stir the mixture until it reaches the desired consistency. If it is too sticky, add a small additional amount of liquid starch. If using a baggie to mix, close the baggie tightly and knead the mixture until it thickens.
Liquid starch is available in the laundry section of your local grocery store. Chill the silly putty to make it keep its shape longer and bounce higher.
