Bath Fizzies

Learn how to make bath fizzies to give as handmade gifts.




All it takes to make delicately scented tablets is a little mixing, some gradual spritzing, and a few minutes of molding. When you're finished you'll have dozens of effervescent treats in a variety of shapes and colors that will scent and soften bath water as they bubble. Stuff stockings with cellophane bags filled with stacks of the colorful blocks. They make great gifts for all the ladies on your list, including mothers, grandmothers, aunts, and grown-up nieces. Experiment with colors and scents; mix yellow and red to make orange, for example, and try blending lemon with lavender.


  • Baking soda
  • Cornstarch
  • Citric acid
  • Spritzer bottles
  • Food coloring
  • Glass bowl
  • Essential oil
  • Baking molds


  1. Step 1

    Sift 1 3/4 cup baking soda, 1 cup citric acid, and 2 cups cornstarch through a sieve to remove chunks. To make different tints, fill small spritzer bottles with water and add about 6 drops of food coloring to each.

  2. Step 2

    Pour 1 cup of powdered mixture into a glass bowl. Lightly spritz, stirring after each spritz, until powder is desired color. Add water slowly, so mixture does not fizz. If mixing two tints, alternate colors as you spritz. Check the consistency of powder with your fingers; when it can be tightly packed or shaped, stop spritzing (this may take a little while).

  3. Step 3

    Select an essential oil. Add 5 drops if it's one of the stronger scents (peppermint, lavender), 6 if it's a weaker one (lemon, grapefruit). Mix well. Firmly pack mixture into small baking molds. We used 1/4 cup for each fizzy, which is good for one bath. Allow mixture to set for 2 hours, then pop out carefully. Repeat with different tints for remaining powder.

    I made these today, it was a little time consuming but I am using them as Easter gifts. Can't wait to try them out!

  • Klaudia PL 2 Jul, 2014

    I find the article helpul and clear. I prefere for bath bombs the food powdered colorants. I love mix the colours on bath bomb and make the great colorful bath water.

  • Susan L W 3 Nov, 2013

    This seems helpful from another reviewer. Thanks other person.

  • jcainltd 12 Jan, 2013

    you can also find citric acid in the kosher aisle your grocery store, labeled as 'sour salt'.

  • Geekamicus 5 Dec, 2012

    These worked out very well. I think the secret is using the spritz bottle sparingly -- spritz, stir, spritz, stir. as soon as it starts to foam, stir it in. It takes a while, but it starts to stick together when you squeeze it. I was also afraid of the food coloring dying skin so I added twice as much water to the bottle and my fizzies have just a hint of color.

    I found the ingredients -- citric acid, especially -- in the canning aisle at Walmart. I also bought a nice silicon candy mold there.

    They came out perfect! Thanks Martha!!!

  • sammyj87 23 Nov, 2012

    A friend and I just made about 3 batches of these. We used a spray bottle with Witch Hazel in it. It causes the fizzies to hold and harden. Use about only 3/4TBS of water! Don't use to much!!! Mine turned out fantastic!! If you don't have a lot of molding options laying around - ICE CUBE TRAY!!! works wonders!

  • Erichey1993 20 Nov, 2012

    I tried this and every time I tried to take them out of the molds they broke and crumbled everywhere. I added more water, thinking there wasn't enough water in it. I also tried leaving them in longer, 24 hours, and still they crumbled. Any advice?

  • love4 7 Sep, 2012

    Made this recipe and yes it started to rise everywhere!! is there any way i can save what i have made?

  • stacy 14 Aug, 2012

    Just throwing it out there but Martha's post say Holiday 2006. The link to pin cookie says May 6 2012.... I might be mistaken but to me that would show that Martha had this word for word first.

    If you want to talk about who ripped of ideas...Lush Fresh Handmade Cosmetics invented bath bombs. I'm sure it's nice to make them cheaply at home, but if you want the real experience I suggest trying some from Lush. They're also handmade, use vegetable dies, have no preservatives, and have the highest quality essential oils and ingredients.

  • lalaladodo 2 Jan, 2015

    Yes lush bath bombs are very nice to use but making them at home can be more enjoyable than just going to a store and buying them. Also I don't enjoy much of the scents at lush and with making one you can personalise your scent just how you want it. Also lush bath bombs are anywhere from 6-8 dollars which is quite a bit of money to spend on a one time thing, one more thing is that people might not have a lush near them to buy them from.

  • Becky_458 28 Jul, 2012

    @jmwolff2 If they didn't fizzle in teh water you might not have added enough citric acid. You could try it with slightly more citric acid. Or when adding your water don't quite add as much as when it fizzed. Hope this helps :)

  • jmwolff2 12 Jul, 2012

    I made these with my kids today. Some of them fizzled a little in the mold (too much water?) and some seemed moistened just enough to mold. None of them fizzled in the water. Any ideas why not?

  • Melissa Lamphier 9 Jul, 2012

    @khayes08 - I put food coloring in my son's bath water to help him learn his colors and nothing has been stained except for my hands when I'm not careful and get the color directly on the skin. =) I am sure the very small amount in these will probably not even show up in the water as I have to put in quite a bit to tint the whole tub.

  • khayes08 9 Jul, 2012

    I'm guessing the food coloring will be so diluted in a tub full of water that they won't stain your skin, but I am going to ask anyway. Has anyone actually tried these to know for sure?

  • Carol Arneson 1 Jul, 2012

    How do you know who stole whos idea???

  • sajwallace 9 Jun, 2012

    Citric acid can be found at walmart in the kitchen section with canning goods. I have also found that essential oils and soap bases and molds can be found wholesale at

  • Ubu71 1 Jun, 2012

    I'm guessing if they start fizzing in the molds I've put too much water :) am leaving them just in case they settle down but reading other comments it may take me awhile to get it right LOL

  • JillyBean78 17 May, 2012

    FYI Martha & friends, I saw this lovely post ripped off word-for-word on another site:
    They even stole your photo. Dirty rotten content thieves...

  • JustWild21 29 Mar, 2012

    You can purchase the Citric acid in bulk at a bit cheaper that way.

  • BathingNymph 16 Dec, 2011

    I found citric acid at a local beer and wine making supplier. And when it comes to adding moisture, I use witch hazel instead of water. It seems to help out a great deal.

    I just tried the food coloring with my latest batch, and I'm a tad bit afraid of staining my skin in the bath, but I'll trust Martha's judgement.

  • msawats3 11 Dec, 2011

    You can get them at the pharmacy. Ask your pharmacist!!!

  • mjb5019 25 Nov, 2011

    If you can't find citric acid- try Fruit Fresh

  • kelseystanton 3 Nov, 2011

    These are a tough project but people love them. Trying to find that balance of enough water is the key. It took me about 3 batches to get them right.

  • poucecoupe 9 Jul, 2011

    where do you get the citrus acid ,i live in a small town

  • Ladyboy 29 Dec, 2010

    Personally, when making bath fizzies I use a equal amount of citric acid, baking soda
