In a small mixing bowl, pour in 1 cup of water, add 2 teaspoons of borax powder and stir to dissolve, set aside
In a large mixing bowl, pour in 1/2 cup of water, add the entire bottle of Elmer’s school glue and stir until well blended
Add enough green food coloring to obtain the desired color to the glue mixture and blend well.
Give the borax-water mixture another few quick stirs and add to the glue mixture.
Stir the mixture until it becomes solid, (there will be leftover liquid), gather the solid material with your hands, working the green goo or slime together to make it more solid.
Form the green goo solid mixture into a ball and dispose of the liquid
Work the mixture gently until it forms a ball and most of the liquid is gone.
Place your green slime in a closed container to keep it fresh
