DIY Milky Way Galaxy Bath Bomb Tutorial

I know, I know…I’ve been going sewing crazy lately and I forgot about all of my spa peeps out there. For this, I apologize. So how about I make it up to you with a nifty tutorial on this galaxy swirling technique using my Milky Way bath bomb recipe! I love this recipe so stinkin much. It’s not only called the Milky Way because of its design; this bath bomb recipe is chock full of soothing and nourishing ingredients such as powdered milk, jojoba oil, and honey.

So the first thing you’ll want to do is get the recipe by clicking on this link.

First, we’ll be starting by mixing our dry ingredients. Make sure to sift your citric acid and baking soda if you have any clumps. Soft clumps in the powdered milk or honey will break up with the beater, but if you’ve got hard lumps you’ll want to sift those too.

Next, we’ll be measuring out our wet ingredients. Now you know this is a special recipe when you see me pull out the Queen of oils – Jojoba. She is beautiful, and emollient and I love her oh so much.

The fragrance oil I chose for this bath bomb is this Cardamom True Sugar fragrance oil by Crafter’s Choice.

Start by beating your dry ingredients on their own. Cover your mixer with a towel to keep the ingredients from getting too airborne. Once again, if you want to see the measurements for the dry and wet ingredients, get the free recipe above.

Once the dry ingredients are mixed well, slowly add in your wet ingredients and mix until everything is fully incorporated.

The finished product should have this consistency:

Next, we’ll be dividing up our batch into four. To get the exact weight of each batch, see the recipe.

Then we’ll be coloring the different batches with some vibrant galaxy-esque hues. Once again, the different colorants and their amounts are covered in the recipe.

And here comes the fun part! Check out the video below to see how to mold your own Milky Way galaxy bombs.

Pin this for later!

    Hi. I was interested in purchasing the recipe, but we don’t have access to powdered honey here – I’ve just checked. is it a vital ingredient? thanks

    1. If you don’t use the honey powder you’ll need to substitute a different dry ingredient in it’s place. I haven’t tested it with this recipe, but my first pick as a substitution would be colloidal oatmeal because it has a similar density to the honey powder. If you don’t have access to that my second substitution suggestion would be bentonite clay. Like I said, though, I haven’t tested substitutions with this recipe so I can’t tell you which would be the best option until I do. 🙂

  2. Hey i can’t find any citric acid at my grocery stores. Is there a substitute for it? Or were can you even buy it?

  3. Hi!

    Thanks for sharing! I tried this and my bath bomb won’t stay together. I am guessing this is because I used too many dry ingredients to the wet ingredients. Do you have any suggestions? Also, can I prepare the bowls of ingredients a day in advance before I create the bath bombs? I am doing this for a large event and need to find the best way to make this happen. Thanks!

    1. Hi Kimmie! You can use a spray bottle filled with alcohol and spritz your mix once or twice at a time then mix to get the correct wetness. You can divide out your dry ingredients a day in advance if you would like. Just make sure they are placed in a sealable container to prevent any humidity from activating them.
