10-12 drops wintergreen essential oil (or your favorite essential oil)
Sprinkle 1 teaspoon of multi-colored non pariels into each Christmas tree mold and set aside.
In a medium glass or metal mixing bowl, add the baking soda, citric acid, corn starch and epson salt. Whisk to combine.
In a small mixing bowl, add the water, coconut oil, essential oil and soap colorant. Stir to combine.
Very slowly, add 1 tablespoon at a time of the liquid to the dry ingredients and whisk after each addition. You do not want the mixture to bubble too much and become activated. (A small amount of bubbling is ok). The bath bomb mixture is ready when it resembles damp sand and holds together when you clump it in your hands.
Transfer the mixture to each tree mold and fill about 3/4 of the way (there will be some expansion so you want to leave room). Press down firmly and allow to dry overnight.
Carefully pop each bath bomb out of the mold and store in a dry and airtight container.
HOW TO USE YOUR BATH BOMBS
Fill your bathtub with warm water and drop the Christmas tree bath bomb into the bathtub.
Enjoy your relaxing bath as the uplifting aroma of wintergreen fills the air. The coconut oil in the bath bomb will moisturize your skin and the Epson salt and baking soda will soothe your tired muscles. ENJOY!!
