2 parts white glue (Elmer's)
1 part Sta-Flor liquid starch

Mix well. Dry a bit before it is workable. It may be necessary to add a touch more glue or starch. You will have to experiment. It may not work well on a humid day. Store in an air-tight container.

If you use Elmer's school glue instead of regular white, it doesn't bounce or pick up pictures, but it makes a gooey delight. Use on a smooth surface.

Homemade "Silly Putty" has the same nasty characteristics of commercial "Silly Putty". Beware of contact with clothes and carpet or your Mom & Dad will be angry!
