Servings 6 depending on size of mold
Author Erin Henry

Ingredients

  • 1 cup baking soda
  • 1/2 cup citric acid
  • 1/2 cup Epsom salt
  • 1/2 cup corn starch
  • 1 teaspoon water
  • 3 tablespoons. oil olive, coconut or caster oil
  • Vegetable-based food coloring any color you want
  • Your choice of essentials oils
  • medium bowl
  • whisk
  • small bowl
  • bath bomb molds

Instructions

  • Step 1
    Place the dry ingredients in a bowl and mix together with a whisk.
  • Step 2
    In the small bowl, mix the liquid ingredients together until well blended.
  • Step 3
    In the large bowl, slowly add the liquid mixture to the dry ingredients at little bit at a time. Mixture should hold together when squeezed without crumbling.
    Important Tip: Don’t mix the wet and dry ingredients too quickly.  This will activate the mixture and it will begin to fizz.
  • Step 4
    When well mixed, pack the mixture into your bath bomb mold and pack tightly, then let it dry. Make sure you work quickly so the mixture doesn’t dry out in the process.
    Bath Bombs need a day to several to fully harden. If they’re not quite hardened enough, they may crumble when you handle them, so check to make sure before taking them completely out of the mold.
