Active Time20 mins
Drying time1 d


  • Stainless steel bath bomb mold
  • Spray bottle filled with rubbing alcohol
  • 1 large mixing bowl
  • 2 small mixing bowls


  • 2 cups baking soda
  • 1 cup citric acid
  • 1/4 cup cornstarch
  • 1/4 cup dead sea salts
  • 1/3 cup coconut oil
  • 1 teaspoon polysorbate 80
  • 1 teaspoon elderberry syrup
  • 1/2 teaspoon Elderberry scented oil
  • Purple soap colorant
  • 1 teaspoon purple cosmetic glitter


  • In a large mixing bowl, add the baking soda, citric acid, dead sea salts and cornstarch. Whisk dry ingredients together.
  • Add the coconut oil. This binds all the ingredients together, so you bath bombs don’t crumble when you touch them!
  • Add the polysorbate 80. This helps the coconut oil disperse more evenly in your bath water, makes the bath bombs bubbly and prevents the mica from sticking to the side of the tub. 
  • Add the scented oil. Mix well.
  • You may need to use your hands to break down any lumps and make sure everything is mixed in. The mixture is perfect when it holds together when you press it into your hands and feels like wet sand. Separate the mixture evenly into the 2-small bowls.
  • Add 1-2 drops of the purple color to one bowl. Don’t add more than that at a time because it will make the mixture foam up. Mix well.
  • Now mix in the elderberry syrup. If the mix is not dark enough add 1-2 more drops of the color, but no more or it will be too wet. 
  • Mix in the purple glitter to the bowl with the purple mix.
  • Layer the colors in your bath bombs molds until the mixture is slightly overflowing. Press molds together and grind to remove excess mixture.
  • Gently tap each side of the mold to release the bombs. Allow to dry a minimum of 24 hours.
