DIY Harry Potter Bath Bombs

How to make Harry Potter inspired bath bombs
Author Crystal


  • 1 cup baking soda
  • 1/2 cup citric acid
  • 1/2 cup epsom salt
  • 1/2 cup cornstarch
  • 2 tbsp grapeseed oil
  • 3/4 tsp water
  • 1 tsp butterscotch oil


  • In a large bowl, combine baking soda, citric acid, cornstarch and Epsom salt. Separate mixture into two bowls.
  • Combine grapeseed oil, water and fragrance in a small cup.
  • Add cosmetic mica powder to each dry mixture bowl. Start at about ½ tsp and increase until desired color is reached. Note: the mixture will darken once the liquid is added.
  • Evenly divide liquid into each bowl while stirring to avoid activating the bath bomb mixture.
  • Layer the mix into the mold and firmly press together. Dry overnight before removing from molds.
  • Wrap or store in a dry, cool place.
