Bombs Away……

I got my package from Brambleberry on Thursday. I was super excited! I was finally able to finish my sister-in-law’s gifts and make bath bombs.

Friday I got all the supplies I needed to make the bombs:

What you need:

  1. Citric Acid – can be purchased online or at a local brewery/wine making supply store. At the stores it can cost $9.95+ for a pound. On I got 10# for $24.50.
  2. Baking soda – 2# costs me $0.79 at my local King Soopers. Brand does not matter.
  3. Witch Hazel – better than water when some moisture needs to be added to the dry mixture. It doesn’t activate it like water. This can be found in the medicinal aisles at the grocery store. It may cost around $3.50 for 16 oz, I cannot remember for sure. I got 10# (the large bottle) for $14 on
  4.  A spray bottle for the witch hazel.
  5. Coloring if you would like something other than white. I got LaBomb colors from Brambleberry. I believe they are not water based coloring, it is not on my mind what the base is right now. You only need a 4 drops for the recipe below. (You will see how “concentrated mine turned out per the request of my lil’ guy). Using too much will turn the water the same color as the bomb. I got 20 mL of Cornflower Blue and Irish Moss for $7.10 and $8.55, respectfully. Oh and don’t forget a dropper or pipettes to transfer colors and fragrances.
  6. You will also need a mold of some kind. The one pictured we used to make one GIGANTIC bomb and then in subsequent photos we used small molds from Joann’s from Wilton – their bite size treat molds work really well and come in fun shapes depending on the season – or use a candy mold, whatever, get creative.
  7. Lastly, you need a scent either a fragrance oil or essential oil. Adjust to your “scent sensititivty”. The recipe below calls for 18 mL or 6 pipettes.

Here we go:

The Basic Recipe: (if you want to make a larger or smaller recipe remember the 2 for 1 rule – 2 parts baking soda with 1 part citric acid)

  • 2 cups of Baking Soda
  • 1 cup of Citric Acid
  • 18 mL of fragrance
  • Witch Hazel – ready to go in a spray bottle. Use amounts depending on how humid it is in your area it needs to be a “dry” mix that will hold it’s shape if squished in your hand.
  • Coloring – 4 drops

For my bombs I cut the recipe way down –

I used only 1/2 cup of citric acid I used 1 cup of baking soda.

Be sure to thoroughly mix your dry ingredients. Make sure there are no clumps.

Just to be sure you do not have clumps – use a sifter to really break up any chunks of baking soda or citric acid. If you do have clumps you will get “warts” on the bombs (you will see them in the giant bomb in a minute).

Next add your fragrance. We used Vanilla because my son does NOT like any other scents I have. This is from They have reasonable prices and a HUGE selection of fragrances.

The next step is to mix these ingredients really well so your fragrance is mixed in well. This amount of oil also helps with the binding of the dry ingredients.

Add your coloring. You will be mixing for AT LEAST five minutes to really incorporate and bring out the color.

This is about 1 minute of mixing. It has a bluish tint to it at this point.

This is after 3-4 minutes of mixing. It is definitely turning blue. Just wait until you see the finished product.

This slightly darker than above; however, my son wanted it really blue so I added two more drops of color.

Get your mold out and be sure it is clean and DRY before you begin to put the mixture in. Prior to putting the mixture in, grab a handful of it and squeeze it. If it holds its form then that is great. If it falls apart spritz with some witch hazel and squeeze again. Repeat as necessary to get a good hold. Remember the more liquid you add, the LONGER the drying time an the finish product will expand and distort as it dries (trust me I KNOW this!)

Be sure to pack the mix in well and up to the top of your molds. Let it sit for five minutes and then gently flip it over and tap lightly on your mold to pop out the bomb.

Once you have the bombs out set them aside to dry for at least 4-8 hours. They fizz up really well and have a great scent!

 For fun we made this big bomb (at least a 2.5 inch tall/wide cube), which began to take on a life/shape of its own. It is all in good fun and for practice. I have a second recipe I will post that I like much better than this one.

You can see “warts” on it. That means some of our materials began to clump in the process. I don’t mind it so much, it is going to be thrown in the water anyway, however, you may not so mix well and be sure you still have a fine power after adding the oils and witch hazel.

I don’t take baths and I use these in the shower. Place it on the tub floor and when water hits it, it will activate and you will get a lovely scent in the steam.

If you have a recipe that you use that you really like, feel free to share, otherwise use this one (as it is pretty universal) and let me know how it turns out. Kids love these. They add 3-5 minutes of good giggling/fun to bath time.
