2 c. white all-purpose glue
1 c. liquid starch
Food coloring (optional)
Containers to mix & store

To make: Pour the glue into a container (big enough to use your hands for mixing). Add food coloring to the glue before the starch is added. Gradually add the starch to the glue using your hand to mix the 2 liquids. The mixing takes 10-15 minutes to reach the consistency of silly putty. It may seem like the mixture will not come together, but it will. Add more glue if the mixture seems too thick more starch if too thin. Store the silly putty in airtight container.
