Mix equal portions of Elmers ® glue and liquid starch. The mixture will look a little stringy at first and you may have to knead it with your hands for it to gel properly. If you want colored Silly Goo, add the food coloring at the beginning. If the mixture seems off, try adding more starch (that's what is usually needed if you start with equal amounts). It may take a few tries to perfect it, but once you do, it lasts for weeks in a covered container! Good luck!
Put in white glue, water and food coloring and stir.
Add borax and knead thorougly approx. 5 min. (Wear rubber gloves unless
you want your hands the same color.)
