SILLY PUTTY
2 parts Elmer's white glue
1 part Sta-Flo liquid starch
Mix together and enjoy! It must be Elmer's regular white glue (not school glue) as it will not have the bounce. This needs to dry a bit before it is "workable". It may be necessary to add a touch more glue or starch. You will have to experiment. Store in an airtight container.
