Our local markets all have a section where they sell fancy soaps. Frequently, sitting with these soaps, are a bin of bath bombs. My 5-year-old has become obsessed with them. The idea of having something that smells good and fizzes in his bath is really appealing to him. The biggest problem: they’re $5 each.
The high cost, in addition to some questionable ingredients, led me to decide that we were going to make our own bath bombs. I mentioned to a friend of mine that we were going to do this, and she decided to join us.
Her joining us was beneficial for two reasons: one, she’s a lot of fun and she’s great at making things; and, two, when my recipe was failing (it wouldn’t hold together), hers came to the rescue and saved our bath bombs.
I’ll present her recipe below. Unfortunately, I don’t know where she got it. I asked her, and she didn’t remember. So, thank you to some great resource out there! If my friend finds the link, I promise to add an attribution.
Where to get the ingredients:
Baking Soda: available in any grocery store
Sea Salt: available in any grocery store, or you can get what I use HERE.
Citric Acid: we found this in our local health food store, but it wasn’t where I expected it to be. It’s used in preserving jams and jellies and such. If you can’t find it: ask. In our store, it ended up being with the bulk goods. It’s also available at brewing and winemaking supply stores.
Essential Oils: I order mine HERE.
Grapeseed Oil: I bought this in the oil section of my local health food store, or you can order it HERE.
Molds: You can buy these at a craft store, or use muffin tins (your bombs should drop out if they’re tipped upside down after they’ve dried completely). Ice, soap, or candy molds should work. Also, a melon-baller could help you to shape them. You can find them online HERE or HERE.
Fizzy Bath Bomb Recipe
1 cup baking soda
1/2 cup citric acid
1/2 cup sea salt, fine ground
2 1/2 tablespoons grapeseed oil (or other oil of choice)
3/4 tablespoon water (plus more, if needed)
15 drops essential oil (we used peppermint – energizing – for one batch, and lavender – calming – for another)
- Place the baking soda into your work bowl. Add the almond oil and essential oils and mix well. We mixed with our hands.
- Mix the citric acid and sea salt together, than add those to your work bowl. Mix everything well.
- Add water as needed until the mixture holds when you press it together. Add only the very minimum water required one drop at a time, or use a spray bottle; otherwise, you will set off the fizzing reaction while you’re mixing, instead of saving the fizzing for the bath tub.
- Press the mixture into your molds. We made 12 smaller bombs (well, assorted sizes – they were pressed by my 5-year-old) with this recipe. You could also make 6 big ones of the size we typically see in the store.
- Let sit until completely dry (we left ours for at least 24 hours).
- Store in an air tight container.
To use: Drop one bath bomb into your full bath tub. Enjoy watching it fizz and smelling the aroma it releases.
UPDATE: Our bath bombs didn’t hold together super well once they dried. I think next time we’ll add an additional tablespoon of oil. They smelled amazing and fizzed really well.
