Ariel Bath Bombs

Here at Ruffles and Rain Boots, my daughter and I are having so much fun coming up with Disney Princess bath bombs for a Disney vacation countdown. We’ve made so many already and have even given some away as gifts. 

One of my daughter’s favorite Disney princesses is the Ariel, The Little Mermaid. These Princess Ariel bath bombs are colorful, fizzy, and fun. We didn’t put anything inside like our Moana bath bombs, but if you are making these for a party, slip a little favor in the mold and really WOW them. Let’s get started.

Tips to Make this Favor for your The Little Mermaid Party 

  • Do not use food coloring for your Princess Ariel bath bombs. It will make your bath bombs bright but it could stain your tub. 
  • Do you prefer showers? Mold this recipe in any flat-backed design so they will be safe for use as shower fizzies. 
  • Use any scents you want and any brand of oils.
  • If your bombs crumble, see this article on trouble-shooting bath bombs and shower fizzies to find out your options to remake them. 
  • There is an ingredient which is optional, Polysorbate 80. The purpose of this emulsifier is to limit the oils and butters from pooling at the top of the water, as well as to reduce mica from adhering to the walls of the tub. 
  • If you want to use your Ariel bath bombs immediately, great, go for it. But the fizz isn’t going to be as awesome as it could be. Let the Disney princess bath bombs dry for at least 24 hours to get the most fizz for your bath. Plus, if there’s a little mix-up in your mix, a dry bath bomb will usually work that out.
  • Keep your bath bombs at top-peak-fizzy-potential, by storing them in an air-tight container.

Difficulty Easy
Estimated Cost $3


  • 2 cups baking soda
  • 1/2 cup citric acid
  • 1/4 cup cornstarch
  • 1/4 cup Epsom salts, fine grain works best
  • 1/4 cup white kaolin clay (optional)
  • 1/3 cup coconut oil
  • 1 tablespoon polysorbate 80, optional
  • 10-20 drops of basil essential oil
  • Red mica powder
  • Purple mica powder
  • Teal mica powder
  • Red cosmetic glitter
  • Purple cosmetic glitter
  • Teal cosmetic glitter

  1. In a large mixing bowl, add the baking soda, citric acid, Epsom salts, white kaolin clay and cornstarch. the little mermaid bath bombs supplies laid out on a wood table
  2. Whisk dry ingredients together. step two, combining dry ingredients to make ariel bath fizzies
  3. Add the basil essential oil to the coconut oil.

This binds all the ingredients together, so you bath bombs don’t crumble when you touch them! bowl of white material and oils on top in a clear bowl with a whisk on a light green linen with leaf motif to illustrate how to add oils to little mermaid bath bombs
  5. Add the polysorbate 80. This helps the coconut oil disperse more evenly in your bath water and prevents the mica from sticking to the side of the tub. Mix the ingredients together. I use my hands to break down any lumps and make sure everything is really mixed in there. The mixture is perfect when it holds together when you press it into your hands and feels like wet sand. Separate mixture into 3 small bowls, one with a bit more in it (this is the teal bowl for me).
  6. Add 1 tablespoon of the red mica and red cosmetic glitter into one of the small bowls. Add a bit more color if the mixture is too light. Continue to add a bit and mix until you get the color you want. Repeat with the teal and purple mixtures. Mix each bowl until color is well blended into the bath bomb mixture. photo collage of how to make ariel bath bombs step 4 add mica poder and body glitter to ariel bath bombs
  7. Add a small amount of red mixture into one side of the mold. Do the same with the purple and then fill the remainder with the teal. Fill the other side with the teal. Press both sides of the mold together firmly, grinding together to get rid of the excess mixture. layer colors in bath bombs molds for little mermaid bath fizzies purple on one side and teal on the other on a light green table with leaf motif
  8. Tap both sides of the mold and gently release the bomb. Allow to dry a minimum of 24 hours. If your climate is wet or cold, allow an additional 24 hours. My rule of thumb is that when it is hard to the touch, they are ready for the tub! Store in an airtight container until ready for use. two disney princess bath bombs ariel in a tiny bath tub with purple and teal glass beads
