Ariel Little Mermaid Bath Bombs

Is there a Little Mermaid fan in your family? If you have a child who dreams of being a mermaid like Ariel you’ll enjoy making these mermaid bath bombs with them. It’s a fun activity that is fun to do together and the mermaid tails make bath time more fun for your real life mermaid.

What Are Bath Bombs?

These are mixtures of baking soda, citric acid, oils and waters that react when mixed together. When they come in contact with water, they create a fizzing effect while releasing wonderful scents.

Bath bombs are a great way for kids to have fun in the tub and get clean at the same time!

Why We Love These Mermaid Tail Bath Bombs

Bath bombs shaped like mermaid tails for kids? It doesn’t get more fun than that! Making bath bombs with your children is fun for them and will help develop fine motor skills.

The beautiful colors and sprinkles give the bath bombs a special touch. In fact, the sprinkle mixture includes mermaid tails and other beautiful treasures, just like Ariel kept in her under the sea collection!

All you have to do is mix together dry ingredients in a bowl, then use an ice cream scoop to fill up the molds, and let them sit.

This activity can be messy so I recommend doing it either outside or in the kitchen over a cookie sheet or tray for easy clean up.


How to Use Bath Bombs

One of the ways my daughter uses her bath bomb is by breaking it up first. She puts half in her tub and half under running water from the faucet.

This fills up the entire tub with color and great smells which makes for tub time.

How to Make Mermaid Bath Bombs

You might think that making homemade bath bombs is hard, but they are actually pretty simple to make.

You will need a few specific ingredients which you will find listed below, and these mermaid tail shaped bath bomb molds.

The mermaid bath bomb mold allows you to make up to 16 mermaid tail bath bombs at once so you will have plenty to give as a gift and still have some left for yourself!

Here is everything that you will need to make mermaid bath bombs and the directions that you will need to follow.


  • 1 cup baking soda
  • 1/2 cup citric acid
  • 1/2 cup cornstarch 
  • 1/4 cup Epsom salts
  • 2 tbsp melted coconut oil
  • 1/2 tsp essential oil blend- I like to use this relaxation blend for my kids but you can also add some essential oils like eucalyptus for stress relief or some calming like lavender to your bath bombs to help kids relax and breathe easier.
  • 2 tsp rubbing alcohol
  • 1 tsp blue, purple, or hot pink mica powder- I used Okinawa Blue mica powder.
  • 1 tsp Gold Nugget mica powder
  • 2-4 tablespoons mermaid sprinkles blend



In a large bowl, whisk together the dry ingredients including the baking soda, citric acid, cornstarch and Epsom salts. 

Combine the melted coconut oil, your essential oil blend and alcohol together in a second bowl, mixing well. 

Add liquid ingredients 1 tsp at a time to the dry ingredients, mixing it together slowly so as not to start a fizzy reaction. 

Add in the blue mica powder to the bath bomb mixture and mix well. If you want more color, add some additional mica powder 1 tsp at a time. Checking the color between each scoop.

Dust the bottom of the bath bomb mold with the gold mica powder using a thin, dry paint brush

Immediately pack the bath bomb mold overly full of the blue mixture. Then pack it down tightly and remove excess from the mold.

Press 1 tsp of sprinkle mixture into the back of each bath bomb.

Give the bath bombs about 24 hours to rest in the bath bomb mold before removing them by gently tapping the sides release the mermaid tails.

Store your bath bombs in an airtight container until you’re ready to use them. If you’re gifting them, wrap cellophane around them tightly and label them.
