Secret to Stretchy Slime!
Equal parts water and glue ---mix before you add food color (or paint)....Mix in a separate container a cup of warm water and a teaspoon of borax--mix well to disolve.
HERE"S THE SECRET: add just a spoonful of the water borax mix to glue water mix...maybe two but one at a time---but DO NOT add more spoonfuls until you mix well with spoon or hands. Little by little....and you won't use much of the borax water mix at all so there will be plenty of that leftover.
Don't add more until you're absolutely sure it's still too drippy then add just a little at a time!
