Heat the water in a microwave safe cup until it is boiling.
Combine your dry ingredients, with the exception of the food coloring, in a mixing bowl. Mix well. Add in the boiling water and oil. Continue to mix.
Continue to stir the mixture well until a paste forms. If the paste is sticky, you can sprinkle in flour a teaspoon at a time until the stickiness is gone.
Your play dough can now be colored. Add a few drops of green food coloring to the dough. Continue kneading until the color is distributed.
Sprinkle in the teaspoon of glitter. Knead the dough well so it distributes.
This play dough can be stored in an air tight container or zip lock bag where it will keep for
weeks. You can also add additional drops of essential oil as time goes on to freshen up the smell and calming properties.
