Invigorating Foot Soak

This fizzy bath bomb foot soak is step one in our luxurious home pedicure routine. The soak contains 1st Distillation Peppermint Essential Oil, which leaves a pleasant cooling sensation on your feet, while the Epsom Salts are calming and soothing.

The Round Bath Bomb Clam Shell Mold acts as both the mold and the packaging for these little bombs, and you can complete the entire project by attaching the cute tag, which is available for free as a PDF download.

This project is part of the Happy Feet Home Pedicure series. See all the projects here: Moisturizing Heel Balm, Rose Clay Foot Mask, Cranberry Seed Foot Scrub and Summer Shimmer Nail Polish.

ONE: In a large bowl, combine baking soda, citric acid and epsom salt and stir to combine.

TWO: Using your hands, break up any clumps. If you can’t get them all, you can sift your mixture through a strainer to break them up.

THREE: Add the chia seed oil and peppermint essential oil. Use your hands to combine the liquids with the powders breaking up any large clumps.

FOUR: Depending on the moisture level of the current mixture, spritz the bath bombs with witch hazel. It usually takes between 5-7 spritzes, and the mixture should be wet enough so when you squeeze the powder in your palm, it will stick together. If you don’t have witch hazel, adding a few extra drops of chia seed oil will also help the powders stick.

Note: You want to spray enough so that the powders stick together and aren’t crumbly. Be careful though because spraying too much can cause the mixture to fizz prematurely and ruin your bath bombs!

Firmly press this mixture into both halves of the bath bomb mold. Carefully remove any powder that fills the outer edges; doing so will make the bath bomb molds easier to close.

SIX: Mound a little extra mixture in the center of one half of the mold. Match the eyelets of each side up, and press together. To avoid any imperfections on your bath bomb, make sure to direct pressure to the edges of the mold rather than the center.

SEVEN: Continue filling until all the molds are full. Clean off any stray bits of fizzy ingredients, attach a label and you are done!

EIGHT: Unmold the fizzy when you are ready to use it (leaving your fizzies out in the air can often set off the fizzy reaction in humid climates). The bath bomb molds are intended for one time use, but if you are very careful when you unmold them you can re-use them. They are a mold & package all-in-one!

    Okay first time making these I don’t know what I did wrong they kept popping off, I used like 5-7 sprays of the witch hazel, chia oil and lavender mint fragnance oil but some stayed together and others kept popping open. I did have my air on in my house but I was scared to put them in my workshop because it was so humid out there any suggestion.

      Hi Renee!

      I’m thinking those fizzies may have gotten too moist and started to expand, that’s why the tops kept popping off!

      If you’re in a very humid area, you may not need witch hazel at all. After your mixture is all together, squeeze some in your hand. If it stays together, it doesn’t need any witch hazel. If it falls apart, add 1-2 spritzes, mix and try again.

      You can see an example of that in this bath fizzy video:

      It can also help to use a dehumidifier to keep the fizzies dry! You can also run a fan over the molds to see if that helps. :)

    I made this and it is wonderful! My only recommendation, if you pumice stone your feet like I do (I’m a runner hence calluses), would be to soak your feet in warm water for a while BEFORE adding the bath bomb…otherwise the oil makes it hard for the pumice stone to work effectively. Then after you’ve sloughed off that dead skin, put the bomb in and let your newly exfoliated feet soak these great bath bombs right up! Also I didn’t have these super cute molds so I actually used lollipop molds that were in fish shapes (bath theme) and although they did lose some detail in the humid Nebraska air, they didn’t work too bad.

      So glad you like the recipe Theresa! Also, that’s a great tip, thank you so much for sharing. That way your feet are freshly scrubbed and can soak in the skin-loving oil. :)

    Hi! We are going to make this project or a similar one for my daughter’s Brownie troop so they can earn their home scientist badges. My Chia seed oil was past 6 months old and smelled a bit rancid so I tossed what was left. Will avocado or grape seed work? Also, I am a bit nervous about using peppermint with little girls so will likely use FO instead and call the project bath bombs. I picked this recipe because of the proportions and packaging. If we have 12 girls I should be able to set up 3 stations. Do you have any tips or other recipe suggestions? I though I saw a post on a shower bath bomb station but can’t locate it now.

    Those molds are brilliant! They are a bit harder to fill than I expected though–if I’m not filling it so firmly that the mixture gets pushed out the other side (thank you, curved bottom), I’m accidentally denting it when I smush the halves together! :p

    Eventually I prevailed, and I can’t wait to use these. 😀 I ended up with five of ’em and a smidge left over, and that’s after one of them exploding over my table when I tried to gently pry it open (yeah, if you accidentally dent it, I suggest just leaving it–I’m gonna be sweeping up grit for days).

    I was wondering would it be OK to add a small amount of ground lavender buds or tea leaves for that extra “soakability”? I’m going to try it without but was curious as to what the folks at BB think. Thanks

        I know this says: Invigorating Foot Soak … but can these also be used as a regular Bath Bomb? I have been trying to find a Bath Bomb recipe that uses Chia Seed Oil b/c I heard that alot of people in the Texas area where I am at says it helps their skin due to the humidity & heat. Please let me know & also can I add Kaolin Clay to this without messing up the recipe. If so how much can I add?

        • Kelsey says

          Hi Cheryl!

          You can absolutely use this as a regular bath bomb! We used it as a foot soak because it’s great for tired feet.

          Also, you can add kaolin clay to this recipe. I would recommend starting out with 1 tsp. and adding more if you like. If you notice this soak is on the dry side, you can add some more chia seed oil. :)

            Hi Melanie!

            Peppermint Essential Oil can cause a cooling effect, which makes a great reinvigorating foot or bath soak. You can definitely leave it out of the recipe if you like though. :)
