DIY Unicorn Fizzy Bath Salts Recipe

This unicorn fizzy bath salts recipe works like a bath bomb, but it's a lot easier to make.

My daughter is 11 now, so she's a preteen and loves all the things that preteen girls like, like rainbows, unicorns, cute animals, and bath bombs.  She's been begging me to make bath bombs for a few months now.  

I have all of the supplies, and I've made them before, but I don't really enjoy making them.  They can get fickle if the humidity is off in your home.  My house tends to be very humid in the summer, so I would just rather not make them.

So I decided to combine two of her loves, unicorns and bath bombs, and make this unicorn fizzy bath salts recipe.  Think of this recipe as a bath bomb in a jar.

It works just like a bath bomb, but it's a lot less fickle to work with.  You don't need a mold, and you don't have to worry about adding water or anything to make it pack into a mold.


This fizzing bath salt has fewer ingredients than making an actual bath bomb, so it's a little easier to make.  

When you make a bath bomb, you add oil and water and mix with the dry ingredients.  The amount of water that you add can vary depending on the humidity in the air, much like making bread.  

Then you have to wait for them to dry, which can take up to 24 hours.  This is ready to use immediately, so it would be a great craft project for kids.  Maybe for her next birthday party we can make these for the kids to take home.  

You don't have to make these in these colors or with this fragrance.  You can use any color or even leave it uncolored.  I just wanted to show a fun way to combine the colors for a pretty presentation.  If you're making this for yourself, you do not need to add any colors.

The base of the recipe is Epsom salts.  Epsom salts, magnesium sulfate, are high in magnesium, which many Americans are lacking in their diets.  It's believed that we absorb magnesium through our skin, so this is a great way to boost magnesium.

The baking soda helps deodorize and soften the skin.  I like adding it to most of my bath salts just because we have hard water.  It also helps add some bulk to this recipe.

The citric acid is what actually fizzes when it hits the water.  Don't be fooled by the term acid.  It's used in canning, and it's a very mild acid.

Since my daughter takes baths at night, I used Crafty Bubbles Calming Essential Oil Blend.  

It's a blend of:
  • Patchoilu
  • Beramot
  • Cedarwood
  • Lavender
  • Clary sage
  • German blue chamomile
  • Vetiver
  • Anise
  • Cassia
  • Myrrh
  • Frankinsense

You can use any essential oil that you'd like.  I think a blend of lavender, bergamot, and rosemary would be great for a unicorn fizzy bath salt recipe.

Just use the same amount of drops no matter which essential oil that you use.  

I used neon food coloring to color mine, except the yellow.  That was from the regular food coloring set.  




Place the dry ingredients in a bowl and mix well.  Use your spoon to press down on lumps to break them up.


I wanted to use four colors, so I separated the dry ingredients into four bowls.  You can separate them into however many bowls as you need colors for.


Add your food coloring.  I used 2-3 drops per bowl, but I made a half batch to make one 8-ounce jar.  I wanted my colors vibrant for the photos.  I would suggest that if you use the measurements as written to only add 1-2 drops of food coloring per bowl or 4-8 drops total for the entire recipe.

Spoon stirring won't do much here, so put on a glove and work the food coloring into the fizzy bath salts by hand.  

STEP #4 

If you used one color, you are done and can transfer it to a jar.  If you want a unicorn or multicolor effect like I did, spoon the salts into the jar in layers if you want.  I tilted the jar and added a few spoonfuls of one color, tilted the jar another way, add more salts, and kept going until it was full.  I did not fill each layer completely, so the colors are all over the place.

The recipe as written will make two cups of bath salts.  You can use up to a cup per bath, but I usually have my daughter use 1/2 cup per bath.  

You won't want to store this in your bathroom because the extra moisture can cause it to get lumpy and start to clump.  For this reason, I don't recommend making more than one batch at a time.  

Also be careful to use a spoon to get the fizzing bath salts out of the jar.  Don't dip a wet hand into the jar because it will start to fizz.  

This should fizz for 10 to 30 minutes.  If it gets humid, some of the citric acid might have already been activated and won't fizz.
