Bath Bomb Recipe – Summer Swim

Preparation Time: 20 minutesCooking Time: 6 hours

This bath bomb will make your tub bubble with summer fun and sea creatures

This bath bomb recipe lets me take a summer swim in the middle of winter. Well, it’s a swim in my bathtub, but still…

You see, I grew up near the Atlantic Ocean in Massachusetts. My childhood was full of surfing the salty waves, finding sea creatures in the tidepools and digging my toes into the gritty sand. Now I live in Texas, far from the ocean. But I’ve created a bath bomb to help me recreate the joy I used to feel during a summer swim.

What I remember clearly is how the ocean waves leave a frothy layer of bubbles on the sand each time in recedes back into the sea. I also remember how the sunshine reflected and refracting in shiny bits off of the ocean’s surface, too.

Follow this bath bomb recipe and your tub will be full of frothy bubbles. What’s more,  you will see the glittery sunshine, too. That’s why I call this bath bomb “Summer Swim.”

“Summer Swim” Bath Bomb Recipe

This recipe uses SLSA, a substance that makes your bath bombs foam and bubble. But it can also make them crumbly. So it’s extra important with this mixture that you get the consistency just right before you pack it into the mold.

SLSA is a very fine powder, so you may want to wear a mask to avoid breathing it in. Or at least make this bath bomb in a room with an open window

I highly recommend making an embed to place in the center of this bath bomb. With the embed, you’ll get extra fizz and spin to create the full ocean effect.

When you add the mixture to the mold, you’ll definitely want to bury the sea creature in the mixture. This way the sea creature will stay stuck in the bath bomb once it dries and you remove it from the mold. Once you remove the bath bomb from the mold, you’ll use a paintbrush to uncover the sea creature.

After I take the bath bomb out of the mold, I use the paintbrush to gently uncover the buried sea creature.

 

This recipe makes 3 large bath bombs with ornament mold or 5 medium bath bombs (will vary depending on size of your molds)

Supplies

  • Rubber gloves
  • Bath bomb molds in spherical shape – I like the plastic ornament molds
  • Mixing bowls
  • Microwave safe bowl (to melt down coconut oil)
  • Paintbrush
  • Spray bottle (for witch hazel)
  • Face mask
  • Measuring cup

 

testing the consistency of the mixture
This bath bomb mixture passes the consistency test because when I squeeze it in my fist, it holds its shape and doesn’t crumble.

Ingredients

  • 1 pack expandable sea toys
  • 2 cups baking soda
  • 1 cup Epsom salt
  • 1 cup cornstarch
  • 2 tsp powdered mica colorant - deep blue
  • 1 cup citric acid
  • 1/2 cup SLSA
  • 2 tsp biodegradable glitter
  • 20 drops Ylang-Ylang essential oil
  • 2 Tbsp sweet almond oil
  • 1 Tbsp cold water
  • witch hazel in spray bottle

Instructions

  1. Open your sphere shaped mold and place 1 expandable sea creature at the bottom of one half of each mold. Set aside.
  2. Put on rubber gloves.
  3. Combine baking soda, Epsom salt, cornstarch, mica, citric acid, and SLSA. Rub the mixture between your open palms to combine well.
  4. Add glitter and and powdered mica. Mix well.
  5. In a separate bowl, mix together Ylang Ylang essential oil, sweet almond oil and cold water.
  6. Add the wet mixture to the dry mixture.
  7. Mix well with your hands, rubbing the mixture between your open palms until just combined. Do not over-mix. Give 1-2 spritzes with witch hazel.
  8. Test consistency by scooping up mixture and squeezing in your fist. Does it keep it's shape like a snowball? If yes, you are ready to pack it into the mold. If not, spritz again 1-2 times with witch hazel, mix with your hands and retest. Continue spraying with witch hazel very slowly and retesting until the right consistency is achieved.
  9. Pack the mixture tightly into your each half of the mold. Important: Be sure to bury the sea creature a bit into the mixture so that it will be held into the bath bomb when the mixture dries. Just leave a bit of the sea creature peek through.
  10. Optional: Add a bath bomb embed. Place it off center in one half of the mold. This will give your bath bomb extra spin and fizz.
  11. Slightly overfill each half of the mold and then press two halves together very tightly. Set aside molds to dry for at least 6 hours. Preferably 24 hours. Leave somewhere that is not humid.
  12. Remove the mold. If you have trouble, tap the mold lightly with a spoon to loosen the bath bomb.
  13. Use the paintbrush to dust off the sea creature on the top of your bath bomb. Drop in the tub. Enjoy your summer swim!
