Homemade Epsom salt bath bombs


  • ½ cup baking soda
  • ¼ cup corn starch
  • ¼ cup citric acid
  • ¼ cup Epsom salt
  • ½ tbsp. water
  • ¼ tsp essential oil
  • ½ tbsp. coconut oil, melted
  • Food coloring
  • 2 hollow plastic ornaments or spheres, halved


  1. Add the baking soda, corn starch, citric acid and Epsom salt in a medium-sized bowl and stir until combined.
  2. In a separate bowl, add the water, essential oil, coconut oil and food coloring and stir until combined.
  3. Slowly add the wet ingredients to the dry ones, a little at a time. Stir between pours to prevent the wet and dry ingredients from reacting or fizzing. (This doesn’t pose a risk, but you want to save that fizzing for when you drop it into your bath!) It should have the consistency of wet sand. If not, stir in ½ tsp of water at a time until it holds together when you press it between your fingers.
  4. Pack each of the ornament halves with the bath bomb mixture, then press the two halves together and place in the refrigerator overnight to set. The next day, slowly open each ornament and remove the top and bottom halves.
  5. Drop into your next bath and enjoy!
