HOW TO MAKE THESE EASY GRINCH BATH BOMBS
If you have made bath bombs before this process should be easy and familiar. If making bath bombs is new to you then I have listed detailed instructions below to make the process simple.
STEP ONE: MIX MICA POWDER
Start off with a small bowl and add the 1 teaspoon of yellow and 1 teaspoon of blue mica powder. Whisk these together so you get the shade of green that you like. Remember that the white in the other ingredients will cause the green to be more pastel so if you want it to be brighter add more colorant now. 
STEP TWO: MIX DRY INGREDIENTS
In another bowl, add 1 cup of baking soda, 1/2 cup of citric acid, 1/2 cup of cornstarch and 1/4 cup of epsom salts. Whisk these together and then add the mica powder color mixture and stir this all together well.
STEP THREE: MIX WET SUPPLIES
In another small bowl combine the 2 tablespoons of melted coconut oil, the 1/2 teaspoon of essential oils or peppermint extract and the 2 teaspoons of witch hazel. Stir these supplies together to combine.
STEP FOUR: COMBINE WET AND DRY SUPPLIES
Add the liquid mixture slowly 1 teaspoon at a time to the dry ingredients. Mix it together slowly as you go so it doesn’t start having a fizzy reaction.
STEP FIVE: PREPARE MOLD
Take one side of the bath bomb mold and dust the bottom of this side lightly with cornstarch. This will help the bath bomb release from the mold easier.
It isn’t necessary to dust the other side of the mold because that side will have the Grinch sprinkles and it usually releases without issues.
STEP SIX: MAKE BATH BOMBS
Place around 1/2 tablespoon of Grinch sprinkles in the non-dusted side of the bath bomb mold.
Now pack this side of the mold completely full with the bath bomb mixture.
In the other side of the mold, go ahead and fill it completely with the bath bomb mixture and add a little bit extra to this side.
Press the two sides of the mold together firmly. It may take some forces and grinding to get the sides together.
STEP SEVEN: SET UP
Now the Grinch bath bombs need to set up. Let the bath bombs rest in the mold for 24 hours.
When you are ready, gently tap the side of the mold to release the bath bombs.
You can use these immediately or store them in an airtight container until they are ready to use!
