Tip: You can buy
molds specific for making bath bombs, but rather than buy something new with
such limited use, I chose to use a 1/3 measuring cup.
What you’ll need…
1 cup baking soda
1/2 cup citric acid
1/2 cup Epsom salt
1/2 cup cornstarch
2 tablespoons olive oil
25 drops fir needle essential oil (Abies
15 drops black spruce essential oil (Picea
15 drops scotch pine essential oil (Pinus
Witch hazel (or other hydrosol) in a spritzer
bottle Evergreen needles (optional)
Blend the baking soda, citric
acid, Epsom salts and cornstarch together in a large bowl. Stir well and
break up any clumps within the mixture.
In a small bowl blend together the olive oil and
Drizzle them onto the previous dry mixture. Stir
Now you need to moisten your salt mixture
without getting it too wet. Spray the witch hazel around the bowl, pausing to
stir every 10-15 sprays or so. (If an area in your bowl gets too moistened, it
will start fizzing; stir it in to stop the reaction.)
After stirring, take a clump of it in your hand.
The mixture is ready when it forms a molded clump in your hands, basically the
consistency of damp sand.
Once you have the desired consistency,
immediately start pressing it into molds. If using evergreen needles, place a
couple in the center of your measuring cup. Less is better here as lots of
needles can be a bother to clean up after your bath. Pack the measuring cup
with the mixture. Use the heel of your hand to pack it in firmly and to create
a relatively level space at the top.
Once it’s packed in the mold, you can tap it out
onto a sheet of parchment or wax paper. The first time I did this, the mold
crumbled. I added a bit more witch hazel to the mixture and then slightly
tweaked my tapping technique. By the third one, I was getting a perfectly
shaped fizzy. Which is all to say that if it doesn’t work the first time, just
keep playing with it and it’ll come to you. Any crumbled fizzies can be
repacked into the mold. Sometime I need to remoisten the mixture before
finishing making the fizzies.
You can use these right away but they will
easily crumble. For best packaging results, let them dry out for 24
Yield: 6 (1/3
cup) bath bombs
Another festive option is to use red alaea salt from
Mountain Rose Herbs in place of the evergreen needles. For the photo below, I
added two tablespoons of red alaea salt to the base dry mixture and then
sprinkled some fresh salt in the measuring cup for the top portion.
If you aren’t feeling the evergreen vibe this year, the base
recipe can easily be varied to suit your tastes. I’ve also made these by
substituting 45 drops of lavender essential oils and using a small pinch of
lavender flowers. One batch I used rose petals and rose geranium essential oil.
The options for variations are endless!
