You're the bomb!

Posted by  ·  February 4, 2011  ·  Last Updated: February 4, 2011

Here is a Friday Flashback about making bath bombs.

Bath bombs  make the perfect Valentine’s Day gift when packaged to look like a bomb along with a tag that says, “You’re the ‘bomb’!”

They would also make cute teacher appreciation gifts!

Homemade Fizzy Bath Bomb Recipe


How to make  foaming bath bombs


2 Cups Baking Soda

1 Cup Citric Acid

4 teaspoons massage oil ( or 2 teaspoons essential oil and 2 teaspoons olive oil)

Spray bottle with water

mold (60 mm 2 part plastic ball) (I am also thinking the bottoms of two large Easter eggs could be used)

This amount only made 5 bath bombs. If I was making more I would buy the citric acid online in bulk. The small bottle you see pictured (1/2 cup) was $2.50. I purchased it from my local health food store.


Mix baking soda and citric acid in large mixing bowl. Mix very well! You can use an electric mixer if you like.


Add in 4 teaspoons of scented massage oil (or other combination of skin safe essential oil for scent and another oil for moisturizing the skin). The scent is personal, so start with a teaspoon or so and add more until you are satisfied. Mix well.


This next step can be a bit tricky because you don’t want your bath bomb to start fizzing. Start by adding a couple of fine mist sprays of water to your mixture and mix well.


You will continue spraying until the mixture will clump in your hand when squeezed. (I used 5-8 sprays, however this will depend greatly on your local climate)


Fill one half of your mold. Pack it tightly.


Fill the other half of the mold and place them together—don’t snap together. I slightly overfilled each half. When I pushed the two halves together they became a ball.


Gently remove the ball from mold. If I had problems with the ball coming out easily I dumped the mixture back into my bowl, added a mist of water (carefully), mixed well and then tried again.


Cut out about a 10 inch circle of black tissue paper.


Wrap tissue up around your bath bomb and trim if necessary.


Place a silver pipe cleaner in the center and then wrap a shiny red pipe cleaner around the the tissue paper and silver pipe cleaner. Add a tag and you are finished! You might want to write instructions for using the bath bomb on the back of the tag.


The bath bomb worked great. It provided fizz, bubbles and fun for my daughter’s bath.

    Can I add some food coloring to give it some color? If so, do I use the powdered one, gel or liquid? Finally, would this be a good birthday present for my mom? It won't be the only thing I'm getting her. Thanks :)

    I tried this, but for some reason mine didn't work. It got in the tub, and it sunk to the bottom and dissolved. No cool fizz. I don't know what I did wrong. :-(

    Is your citric acid in liquid form?

      No Trish, it is powdered/crystal form.

    I've noticed some recipes call for Epsom salts & even corn starch; can I add some to this recipe?
    • Sunday, December 6th, 2015
      I am not sure. It would be great if you could... I love epsom salt baths! Please let us know if you try!

      Saturday, September 17th, 2016
      You can add epsom salts and corn starch to this recipe. I use 1 c. baking soda, 1/2 c. of citric acid, 1/2 c. of epsom salt, 1/2 c. of corn starch, 2 tbs. of essential oils, 2 tbs. of coconut oil, 1 tsp. of water and a few drops of food coloring. They work great!

      It is a plastic two piece Christmas ornament. You can find them at a craft store.

    The previous comment about using witch hazel is true. You can also use a spray bottle with alcohol and it will not create premature fizzing.

    been making bath bombs for some time this is the easiest directions I have seen wanted to say I also use heart shaped tree ornaments or those filled with sweets out around valentines day For these I add some dried rose ,geranium or lavender depending on oils used Perfect as gifts

    This is the best bath bomb recipe ever! I followed your instructions almost exactly, except I used 1 tsp grapefruit essential oil and 3 tsp canola oil, since I knew the grapefruit scent was pretty strong. Thank you for posting!

    I am super excited to make these, but a few things i need to know, i don't want to go and buy the citric acid but I have a lemon zest bottle, would that work?

    Tuesday, November 18th, 2014
    I just made these, they're drying in the oven now. I used a mixture of magnesium spray and witch hazel instead of water, and I added half a handful of epsom salts. I used a mold about the size of a Christmas ornament, but for some reason only got 3 balls even though I added extra ingredients. For the price of the ingredients its probably not worth it for only 3 bombs but it was a fun project with my kid non the less.

    For citric acid purchasing - look for a beer & wine making shops in your area, that is where I found mine, usually much cheaper as they sell in bulk (i.e. 1lb for $3.49 or 50lb for $120 at my store)
  23. Laura Fancher
    Tuesday, November 11th, 2014
    where did you get that mold?
    • Sunday, November 16th, 2014
      It is a plastic ball Christmas ornament found at a craft store. Make sure you get one that come apart in two pieces.

    Sunday, November 9th, 2014
    you can also go to the canning isle at Wal-Mart and buy the citric Acid- make sure that the first ingredient listed is citric acid but it is a lot cheaper than going to the health food store to buy-hope this helps the cost...You can also add vitamin E oil or buttermilk powder which helps makes your skin so soft and corn starch you can use in the ingredients of your bath bomb as well..

    I've made many batches of these- just a word of advice, don't make tem on a rainy day, or day when it is super-humid out or they will not dry properly. You can dry them in the oven on 150 degrees for several hours to speed it up. And one drop or so of gel-based food coloring makes them pretty and won't stain.
  31. Friday, June 13th, 2014
    Hey this was a great recipe for a bath bomb, never thought it'd be this easy! I actually featured this recipe along with some other bath relaxation recipes. divasroom.com/easy-diy-recipes-bath-relaxation Thanks again for posting this recipe!

    If you are adding oils to this mixture, be careful that you don't slip in the tub. The oils are great for the bath, but they make the tub slippery and falls can happen. You can just as easily make these without oils to prevent this, just omit the oil. You can add a touch of food coloring to make them more colorful or use candy molds to make different shapes. Add Kaolin clay to make them harder and the clay is great for detoxification.

    Monday, March 24th, 2014
    Try witch hazel instead of water. The water is activating your baking soda and causing it to start foaming prematurely. Also, you DO need to let them dry for a few days. As they dry out, they will become harder and more sturdy. If you want more foam, you can add some SLSA(Sodium Lauryl Sulfoacetate). It's different from SLS that is very controversial.

    Are you supposed to let them dry after molding them into balls? I made these and wrapped them in tissue paper immediately after.. they soaked the tissue paper and the balls got so deformed they ripped through the paper! :(

    Great read and easy to understand. I have created my own bath bombs and some have been failures. But when I'm on a crunch I buy them from SimplyOrganico.com. I found they make with theirs with lot of butters which leaves me skin very soft.

    I actually make these, but there is a commonly well known secret that if they float, you may as well just watch them from a boat or a moat but if they sink, be sure not to blink, because they sink deep, and are not that cheap. Because if they float, you CAN buy in bulk at a very cheap price both of the ingredients that make them fizz the most, which is the bicarb and the acid. I have seen these in specialty stores, the ones that are HUGE and also filled with loads of soap safe or food safe colorant, that really put on an impressive show, only to have a whole lot of work for the one who cleans that bath when it is all over. But, these so called "Bath Bombs" really don't have too many good benefits at all, when it comes to bathing, actually with this one I just talked about, this child needed a very long soapy shower after to get all of the colorant off. I do make "Bath Bombs" They do fizz, but not like these, they fizz very slowly and gently, and as well they do sink. They have many good healing and wellness properties as well, like magnesium, Jojoba oil, (depending on which type of BB you want) they have all different types of essential, that oils, like my favorite is my relaxation Bomb, has eucalyptus spearmint and lavender. I do use imported sea salts in them as well as other ingredients that are al good and natural, and is a long list as well. I also make a "BIG HOT TUB BOMB" That is safe for hot tubs, and is my biggest bomb, made from an actual old Tupperware Jello mold, that I have had for many years, that has interchangable designs I can change for different decor, or the holidays for a really nice gift! They are quite pricey, but they do take a lot of product to make. I have doubled my batch, to make 5 large balls, and about 7 med. seals (the animals) as well as about 20 square and round 3.5 oz bombs that to me are the perfect size for my bath, to soak in for at least 20 min. to get the full benefits. I also use a fine mist bottle and witch hazel for dampening, in place of water. I do not use water, until I am ready to take my bath. If Herbs and Oils World allows, I don't give out my trade secret for the products I sell, but, I do have another recipe for good health bath bombs, that I will share with all, that are better and have magnesium, as well as other good benefits for your baths.

    I agree with #19. I think the fizzies would make a great teacher gift, but dressing them up like a bomb and bringing them into a school setting is a very bad idea in light of all the recent tragedies. That said, thanks for the cool idea about the fizzies.

    Careful using colorings unless from a natural source. Even food dye/colorings has some of the dangerous Red 40 and Yellow 5 & 6 that more and more people are finding allergies and negative reactions to.
    Same goes for baby oil (mineral oil aka petroleum product). I'd stick with a natural skin helping oil such as olive oil or coconut oil.
  42. Brooke

    Would you be able to put food dye or some sort of colouring in these?

    Can you add color to these? If so what would you use? Food coloring?
    • Sunday, June 9th, 2013
      Danielle, I don't see why not. I would use a gel paste instead of a liquid coloring so it doesn't dilute the mixture. I would keep the color very light. Since the amount of water the bath bomb goes into I don't think there would be a problem with dying the skin. If you try it would you please let me know? Thanks!

    @Sara - I do not think you can substitute pure lemon juice. You need a chemical reaction with the citric acid and baking soda to fizz.
  60. Saturday, August 25th, 2012
    Going to have to give this a try! :) It will be nice to custom make my own with different ingredients. Always the benefit of also knowing what is "really" going into things when you make it yourself (consider myself to be a bit of a health nut).

    Great idea! Only thing - - - in this day and age, it really isn't a wise idea to gift a teacher something wrapped as a bomb. I only say this because I work in the public schools! I am making these for my daughter's teachers, but instead of wrapping them as bombs I am wrapping them in cellophane and putting them in an ice cream container with a personalized label, since they kind of look like scoops of ice cream.
