Unicorn Rainbow Bath Bomb

Bath bombs are on every girl's wish list, and unicorns are super popular. Instead of spending a ton of money buying unicorn bath bombs, you can make your own Unicorn Rainbow Bath Bomb baskets at home. Give them as gifts, keep them for yourself, or make them with the kiddos as a fun craft to do together.

Unicorn Rainbow Bath Bomb Supplies

Keep in mind that buying supplies in bulk will save you time and money. And, you will be able to make more than just a couple of bath bombs.

2 cups baking soda
1 cup citric acid
¼ cup cornstarch
¼ cup kaolin clay
2 tablespoons Tea Tree Oil Epsom salt
⅓ cup coconut oil
1 teaspoon polysorbate 80
1 teaspoon rosemary essential oil
½ teaspoon of pink, purple, teal, green and yellow mica colorant
Stainless steel bath bomb molds
Mini muffin tin (optional)
Spray bottle filled with rubbing alcohol
1 large mixing bowl
5 small dipping bowls
1 small, medium and/or large paintbrush(es)

Step 1

In a large mixing bowl, add the baking soda, citric acid, Epsom salts, kaolin clay, and cornstarch. Whisk dry ingredients together.

Step 2

Add the coconut oil. This binds all the ingredients together, so your bath bombs don’t crumble when you touch them! Add the polysorbate 80. This helps the coconut oil disperse more evenly in your bath water, makes the bath bombs bubbly and prevents the mica from sticking to the side of the tub.

Step 3

Add the rosemary essential oil. 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.

Step 4

Add the mixture into each side of your bath bomb mold until the mixture is slightly overflowing. [If the mixture gets dry as you make your bath bombs, spray a bit of the rubbing alcohol into the mixture.] Press molds together and grind gently to remove the excess mixture. Gently tap each side of the mold to release the bombs.

Steps 5 and 6

Allow to dry a minimum of 24 hours or until rock hard.

Add ½ tablespoon of each of the mica colors into each of the small dipping bowls. Add ½-1 teaspoon of alcohol to each bowl. Mix well.

Step 7

Dip the paintbrush into the mixture and brush one color onto each of your bath bombs. Rinse and dry your brush and repeat until you have used all your colors.
