  • 1 cup baking soda
  • 1/2 cup citric acid
  • 1/2 cup Epsom salt
  • 1/2 cup corn starch
  • 1 teaspoon water
  • 30-40 drops of essential oil (optional)
  • 3 tablespoons. oil (olive, coconut or caster oil)
  • Vegetable-based food coloring (any color you wish)


  • Place the dry ingredients in a bowl and mix together with a whisk.
  • In the small bowl, mix the liquid ingredients together until well blended.
  • 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.
  • When well mixed, pack the mixture into your heart shaped bath bomb mold and pack tightly, then let it dry. Make sure you work quickly so the mixture doesn't dry out. Bath Bombs require 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 out of the mold.
  • Enjoy your pampering bath bomb!


Check to make sure your bath bombs are fully hardened before removing from the mold.  Otherwise they might crumble.
