Sparkle Power Bath Bomb Tutorial

Here’s a kid-friendly bath bomb tutorial guaranteed to make bath time tons of fun. It’s a spin off of the recent Hidden Color Bath Bomb tutorial, where a secret stash of super concentrated color appears once the bath bomb is activated in water. This time around, instead of color the secret stash is full of glitter! What a fun and unexpected treat for bath time adventures.

Sparkle Power


1 Cup Sodium Bicarbonate (Baking Soda)

1/2 Cup Citric Acid

1/2 Cup Corn Starch

1/2 Cup Coarse Epsom Salt

1.5 Tablespoons Avocado Oil

9 mL Love Spell Fragrance Oil

Rosy Pink LaBomb Colorant

Iridescent Glitter

Rose Mold

Witch Hazel

ONE: Place a wire mesh strainer on top of a bowl. Measure out the Baking Soda, Citric Acid and Corn Starch and pour into the bowl through the strainer. Work the powders through the strainer to remove any clumps. Remove the strainer from the bowl.

Sifting powders

TWO: Add the Coarse Epsom Salt to the powders and mix with your hands until combined.

Adding salt to mix

THREE: Add the Avocado Oil to the dry ingredients and mix using your hands until there are no more clumps.

TIP: Wear gloves when mixing if you don’t want to ruin your nail polish!

Adding Avocado Oil

FOUR: Add the Love Spell Fragrance Oil and mix until well incorporated.

FIVE: Color with Rosy Pink LaBomb, mixing in a few drops at a time until you’re happy with the color. But remember, the more color you add, the more likely it is that the bath fizzy will color the bath water, which may not be your ideal result. If you want to know more about LaBomb Colorants, check out the Talk It Out Tuesday post where we answer all your questions!

Adding Colorant

SIX: Spray the mix with Witch Hazel (I used between 10 and 15 sprays). Mix in with your hands until the mixture clumps in your fist.

Spraying with Witch Hazel

SEVEN: Fill the first cavity of the Rose Mold about halfway full with bath fizzy mixture. Pack down the mix into the mold, then add 1/8 – 1/4 teaspoon of Iridescent Glitter in a pile in the center. Cover the glitter with enough bath fizzy mix to fill the rest of the mold. Repeat this step with all cavities.

Adding Glitter

EIGHT: Leave the bath bombs in the molds overnight or until they are hard enough to unmold. These are ready to use right away, or wrap them up and save them for later. Enjoy!

    Hi There,

    I was wondering if you could do a tutorial on how to add a butterball to the middle of your bath bombs. Thank you.


  2. Robin says

    Hi, I noticed that you use a variety of colorants in your bath bombs- usually La Bomb, but sometimes micas or clays… Are they all washable? I’m worried about the fizzles staining bathtubs or leaving a ring that has to be cleaned. Love the ideas though!

    • Kelsey says

      Hi Robin!

      If you use too much of any of the colorants, they can color your bath water and possibly your tub. However, all of our recipes have been tested to ensure there is no staining. If you do notice color or your tub, it should be easy to wipe it away with a paper towel. :)

      Hi Amanda!

      We didn’t use arrowroot flour, so I’m not exactly sure! You may want to make a small test batch to see how it works. :)

        I just tried substituting arrowroot flour and if anything it worked better. The bombs seemed to float higher and were less likely to crumble.

    Can I use silicone molds? the one that you use for ice cubes.
    I made this yesterday and they are a little bit wet, and they can’t hold shape, should I leave them more time in the molds?

    Hi! My seven year old daughter and I have just recently begun making MP soaps, salts and fizzles. What started as a project for her teachers has become a hobby. We recently tried this recipe and were disappointed that it was very soft and crumbled. We used all Brambleberry products except the cornstarch and the coarse Epsom salt – you were sold out of the latter. We were able to salvage a few and remixed them with some kaolin clay but still wondered why the were soft without the kaolin.
    Thanks for any tips you can provide to us. Perhaps we should use a glass versus solid cup measure for the powdered ingredients?

    • Kelsey says

      Hi Marissa!

      I’m sorry to hear that!

      How much oil did you add? How much Witch Hazel did you use? Adding too much of either of those can make your bath fizzies soft.

      Let me know and we’ll figure this out! :)

      -Kelsey with Bramble Berry

      • says

        Thanks, I used the amount of oil that the recipe specified . I used 1.5 tablespoons but measured in apprx ml, so I added 20 ml. I don’t recall how many spritzes of witch hazel, maybe too many?

        The little girls loved them. They were covered in glitter after so next time we will use 1/8 tsp vs 1/4 , but then again, being sparkly was part of the fun.


        • Kelsey says

          Hi Marissa!

          You’re welcome! Witch Hazel can make those fizzies soft. We recommend just spraying enough so that the fizzies clump together.

          Have fun with your sparkly bath bombs!

    I need to make 16 of these for a”spa Class” how much more avocado oil. citrus acid, and colorant should I need?

    • says

      Hi Susan!

      We found this recipe made 5 bath bombs. If you need 16, I would recommend tripling the recipe, or quadrupling it if you want to make sure you have plenty, or would like to make a couple extra :)!

    Hello SoapQueen!
    First of all, would you please excuse my english, I’m french! I tried to do my first bathbomb yesterday. Two differents recepies and…two catastophies! I try the “Sparkle Power Bath Bomb Tutorial”. I didn’t have avocado oil so I put a blend of oil (almond, apricot, sesame…) with NO WATER in it. For the colorant I put some food colorant that I mixed with the oil and a teaspoon of SLSA. I didn’t put some witchhazel because the mix was the exact texture (in my opinion!). The rose NEVER harden and stay very crumbly even 24h after (didn’t unmold them after making them).
    I did an other recipe…and an other catastrophy! Just a blend of oil, acid, baking soda, epsom salt and fragance. I didn’t use witchhazel or water. When I put everything in the bowl, the texture was enough wet. I put it in the mold, it was perfect but 10min after the bathbomb had mushed! They nearly double sized. Now they are ugly but very hard. No mention of water in the food colorant…I’m very perplex.
    Dear Soap Queen, I can’t afford the shipping fee for your product so please, would you accept to help me with this disaster?

      Hi Olivia!

      You can still use the bath fizzies in the tub, and we suggest putting them in either a airtight jar or using water-soluble paper like in this tutorial:

      Save The Bath Bombs:

      With your recipe, I would remove some of the additives and use a basic bath bomb recipe (fragrance, color, baking soda and citric acid) to see if that helps. Your bath fizzies might be prematurely fizzing because of the type of food colorant you used. Some food colorants do use water as their base, so you will want to check out the ingredients list on your colorant.

      With the oil, you only need a small amount, as anything more will cause your bath fizzies to get a bit mushy. Next time, I would try your recipe without those oils to see if it changes how it turns out.

      Keep us updated!

    Does witch hazel have a smell? I bought a bottle of witch at the drug store, it made my bath bombs smell bad. Has any one had this problem?

    Thank , Vontella

    • says

      Good morning, Vontella!

      When we’ve used the witch hazel for our bath bombs, the smell begins to dissipate quickly after it has been mixed in. Was the witch hazel you were using 100% and did you add any extra fragrance to your bath bombs? I’d love to know so that I can help you troubleshoot this! =)

    My 11 yr old daughter and I just made these last night and it was so easy and fun! She dislikes baths, but is really excited to use one. Wow! It really works!! (Persuading kids to bathe, hooray!)
    They smell great too; even my husband was commenting that the house smelled good while we were making them. We’ll have to make the fizzy cupcakes next. I can’t wait!! 😀

    • says

      Hi Sonja!

      We are so happy to hear that your daughter had a blast making them with you. They were one of our favorite projects too. She is just going to love the fizzy cupcakes, they are so much fun! =)

      • Sonja says


        I loved making these so much that I’ve looked at a few of the other bath bomb recipes. I noticed that the other recipes didn’t use corn starch. What is the purpose of the corn starch?

        • says

          Good morning, Sonja!

          We used the corn starch in this particular recipe because it is a binding agent and we really wanted this one to bind well because of the surprise glitter inside! I hope this helps. =)

    Oh how cute! There are so many variations for this…use a wand/fairy mold & call it fairy-dust, a st.patties day mold & call it leprechaun magic, the BB pony mold & call it one of the “My Little Pony” horses…etc. AWESOME gift for little kids (especially little girls between ages 3-6) 😉
    Will definitely try this!
