How Do I Make Rainbow Unicorn Bath Bombs?
Just check out the how-to card below with full materials, tools, and instructions. Any demonstration photos do not print out to save your ink.
- 2 cups baking soda
- 1 cup citric acid
- 1/4 cup cornstarch
- 2 tablespoons bentonite clay
- 2 tablespoons Milk and Honey Epsom salts
- ⅓ cup coconut oil
- 1 teaspoon polysorbate 80
- 2 tablespoons cocoa butter
- 10-20 drops cardamom essential oil
- 10-20 drops cedarwood essential oil
- 1-2 tablespoons of purple, blue, pink, yellow & green mica colorant
- 1-2 teaspoons of white cosmetic glitter in each of the smaller bowls
- Stainless steel bath bomb molds
- Mini muffin tin (optional)
- Spray bottle filled with rubbing alcohol
- 1 large mixing bowl
- 5 small bowls
- Place the baking soda, bentonite clay, citric acid, Milk and Honey Epsom salts, and cornstarch in a large mixing bowl and whisk together.
- Add the coconut oil, cocoa butter, and polysorbate 80 to the dry ingredients and whisk together.
- Add the essential oils and glitter to the bowl and mix well. You may need to use your hands to break down any lumps and make sure everything is mixed in. The mixture is perfect when it holds together when you press it into your hands and feels like wet sand.
- Divide the mixture into 5 smaller bowls. Using 1 tablespoon of each color mica, stir into each bowl so you have five different colors.
- Layer the mixture into each side of your bath bomb mold until the mixture is slightly overflowing. Press molds together and grind gently to remove the excess mixture. Leave to dry for a minimum of 24 hours. Gently tap each side of the mold to release the bombs.
- Store bath bombs in a cool and dry place to prevent premature fizzing. On average, you can store bath bombs for 6 months.
