Witches’ Brew Bath Bombs

Here at Ruffles and Rain Boots, we have a ritual of epic proportions. It involves whiny people (a short, young version of myself in particular) that refuse to get in the bath without the promise of fizzy bath fun time. So, I spend a few minutes every week making something different and exciting to make bath time less of a fight. This week, the kiddo asked for halloween witch bath bombs.

Tips to Make Halloween Bath Bombs

  • Start by grabbing the sprinkles to pop in the top of your halloween bath bombs here . Making embed bath bombs is so easy and using sprinkles means that they’ll melt and not leave any residue on you.
  • If you want a really intensely colored bath bomb, you are going to want to make the mixture quite a bit darker than what you want the final bath bomb to be. The bath bombs fade as they dry and, as far as I know, there’s no way to avoid that.
  • Keep your Lush-inspired bath bombs for halloween in an air-tight container like a mason jar, Tupperware or plastic top-seal baggie. That way they’ll last longer and stay fizzier.
  • If you want to have a really fragrant bath bomb, feel free to add as fragrance, or color, into your witch bath bombs as you want. But please never ever use food coloring to color your bath bombs. If you do, you’ll also color the bathtub and your skin. So, even though it’s might seem less convenient to find soap colorant or mica powders, it’s worth it to take the time. You can find the colorant I used below.
  • If you happen to run into any trouble getting your bath bombs to hold their shape when you pop them out of the mold, they’re probably not starting out wet enough. This recipe is intended to be on the dry side. Just add a little spritz of alcohol or water and try again. But if you keep having trouble, try this trouble-shooting bath bombs and shower fizzies.

Instructions

  1. Whisk together the dry ingredients: baking soda, citric acid, clay and epsom salts. 
  2. Separately, combine the melted coconut oil, essential oil blend and polysorbate 80 together well. 
  3. Add the wet ingredients 1 tsp at a time to the dry, stirring it together slowly so you don't start the fizz reaction. 
  4. Add the two colors of mica powder to the bath bomb mixture and stir until you have a deep purple. If you want la darker color, add 1 tsp of each color mica powder at a time, stirring after each added color until you have the color you want. Remember that the color of the bath bombs will fade a bit when the bath bombs dry.
  5. Using the corn starch and a paint brush, dust the inside of one side of each bath bomb mold. The sprinkle side easily comes out on its own, so I don't usually bother putting cornstarch on those sides of the molds.
  6. Put 1 tsp of the witchy sprinkles in the non-dusted sides of each of the bath bomb molds. 
  7. Pack full each side of the bath bomb mold with the purple mixture, tamping it down with your spoon to get as much into the mold as possible. Mound additional mixture one top of the two molds, then press the mold sides together, pressing hard and grinding them a bit to bond the two parts of the bath bomb together.
  8. Let your bath bombs rest in the molds for up to 24 hours before tapping gently on the top and sides of each mold to release the bombs.
  9. Use these halloween bath bombs immediately or store them in an airtight container until you’re ready for use! photo collage of how to make witches' brew bath bombs
