2 parts Elmer's white glue
1 part Sta-Flo liquid starch

Mix well. Putty must dry a bit before it is workable. It may be necessary to add a bit more glue or starch, you will have to experiment. Store in an air tight container. Homemade Silly Putty has the same nasty characteristics of commercial Silly Putty. Beware of contact with clothes and carpet. Putty doesn't bounce or pick up pictures, but it makes a gooey delight your kids will love.
