Elmer’s Glue – 4 ounces
Borax 20 Mule Team Laundry detergent
Measure 4 ounces of glue into a mixing bowl. Add another 4 ounces water, use plastic spoon to mix well. Add 3-4 drops of food coloring.
Measure 2 ounces of hot water into a plastic cup and add ½ teaspoon of Borax. Stir the solution with a different spoon to dissolve the detergent. This Borax solution is the secret linking agent that causes the Elmer’s Glue molecules to turn into slime.
While stirring the glue in the mixing bowl, slowly drizzle in a little of the Borax solution. Immediately you’ll feel the long strands of molecules starting to connect. Now use your hands to do the serious mixing. Keep mixing with your hand while adding little drizzles of Borax solution to the glue mixture until you get a perfect batch of Elmer’s slime. Do not use all the borax. You might like your slime more stringy while others like firm slime.
Seal it up in a zip lock bag for safe keeping.
