This all natural Pop Rocks Fizzing Bath Salts recipe is perfect for a fun DIY spa gift with an 80s theme!
When I was a kid, I loved Pop Rocks candy. I loved how they would pop and fizz in your mouth!
As I was reminiscing, I thought it would be really cool to make fizzing bath salts that looked like Pop Rocks, so I got to experimenting. I got out my DIY beauty supplies and wrote out a formula I thought might work based upon my experience.
At first I thought this recipe was going to be a flop because it took forever to dry (as in days), but as it finally began to dry, I saw that my experiment was actually a success. The result of my experiment in making Pop Rocks Fizzing Bath Salts is pretty awesome if I do say so myself.
I know one question that will be asked is if you can bake this fizzing bath salts recipe on low heat to dry faster. I did experiment with that, and the fizzing action was greatly reduced when heat was used to assist drying. So I highly recommend air drying.
I used a combination of 2/3 pink and 1/3 purple mica powder to create the pretty pink shade. If you’re looking for something with a deeper hue, more like the candy, you can use soap colorant instead.
Keep in mind that mica does typically leave a ring in the tub and it can be slippery, so that may factor into your decision on which colorant to use. Of course, you could leave them white too and not use any colorant at all. Or you can use polysorbate 80 like we did in these bath bombs to bind the coloring.
How to Make Pop Rocks Fizzing Bath Salts
Supplies
- 2 cups Epsom Salts
- 1/2 cup baking soda
- 1/2 cup citric acid
- 1/4 cup castile soap
- 2 teaspoons sweet almond oil
- 10 drops lavender essential oil
- 10 drops orange essential oil
- Mica powder - or soap colorant
- 4 wide mouth half pint jars
Tools
- Baking sheet
- Parchment paper
- Mixing bowl
- Measuring cups
- Fork
Instructions
- Put the epsom salt, baking soda and citric acid into a medium mixing bowl and stir until well combined. Add the mica powder, if using, to the mixing bowl until you've achieved your desired color.
- Put the castile soap, sweet almond oil and essential oils into a small mixing bowl or measuring cup and whisk to combine. If using soap coloring instead of mica powder, add that here.
- Carefully, pour the soap and oil mixture into the bowl with the dry ingredients. Gently stir to combine. It will bubble up, but do your best to stir as gently as possible.
- Once it’s well combined, dump it out onto a parchment paper lined cookie sheet to dry. I would suggest dividing it up between two cookie sheets to speed the drying process. It took a few days for mine to dry on one cookie sheet.
- As your fizzing bath salts mixture begins to dry, you can break it up into smaller and smaller pieces to help it dry faster.
- Once it’s completely dry, transfer it to a mixing bowl and use a meat tenderizer or potato masher to break the clumps into smaller pieces that resemble Pop Rocks candy.
- As long as the mixture is completely dry, you can transfer it to mason jars for storage. This recipe makes about two pints (or four half pint jars) of Pop Rocks fizzing bath salts.
Exactly how many does this recipe yield? at the top of the recipe card it says 4 Pints but under step #7 it says 2 Pints?
Hi Stephanie, it should make 4 half pint jars. 🙂
This looks so cool! What a fun gift to make for friends or enjoy yourself!
Thanks for sharing! Do they keep long?
You’re welcome. It depends on the conditions they’re kept in. I try to use them within a few weeks. Do you know what oil smells like when it’s starting to get old and go rancid? I find that is the smell these start to get when it’s time to toss them.
Are these kid friendly? My 4 year old loves bath pop rocks but unfortunately they do not sell them anymore. Of course since he is 4 he usually puts or gets water in his mouth.
I wouldn’t use any beauty product with a 4-year old who still puts things in their mouth, especially things containing essential oils. 🙂
Just made this and unfortunately it didn’t work at all. ☹️Followed the instructions exactly. They just partially dissolved in water and left a huge greasy mess. No pop, no fizz. Is there a trick to this?
I’m sorry to hear that Sebrina. I find that when that happens, the citric acid usually got activated by the liquids while they were being made, so there’s no fizz left once they’re dry. You have to go really slow and stir liquids in very carefully so you don’t activate the citric acid.
Can you substitute the almond oil with anything else?
Yes, you should be able to use any carrier oil in place of sweet almond oil. Check out my Guide to Carrier Oils for ideas.
Any recipe that calls for citric acid and baking soda, I add in the citric acid last.
