Winter Storm Icicle Bath Bombs

Winter Storm Icicle Bath Bomb Recipe

Capture the sparkling beauty of those moments after a winter storm with these Icicle Bath Bombs. A gorgeous bath bomb project with a STEAM lesson for the kids.

Servings 6 bath bombs depending on size of molds


  • 2 cups baking soda
  • 1 cup citric acid
  • 1/2 cup corn starch
  • 1/4 cup cream of tartar
  • 1/4 cup Epsom salts
  • 1/3 cup coconut oil
  • 1 tbsp polysorbate 80
  • 10-20 drops Helichrysum essential oil
  • 10-20 drops Lavender essential oil
  • 1 tbsp light blue mica powder adjust as needed to achieve desired colour
  • glitter
  • 2-3 cubes white melt and pour soap base


  1. In a large mixing bowl, add the baking soda, citric acid, cornstarch, cream of tartar and Epsom salts. Mix dry ingredients together.

  2. In the measuring cup add the coconut oil. Heat in the microwave for a few seconds until it becomes a liquid. We need a little extra time for this here in Canada where our coconut oil is always rock hard.

  3. Once melted, add the polysorbate 80, helichrysum essential oil, lavender essential oil, glitter and mica color powder. Mix together with a spoon, then add to the large mixing bowl.

  4. Mix all the ingredients together. I use my hands to break down any lumps and make sure everything is really mixed in there. The mixture is perfect when it holds together as you press it into your hands and feels like wet sand.

  5. Take one mold and fill each side with the mixture until it is over-flowing a bit. Press both sides together, using a twisting/grinding motion to get rid of any excess mixture.

  6. Gently tap each side and carefully remove the bomb. This takes some technique and practice. Be patient. You can repack and try again as often as you need to until you get the knack of it.

  7. As you progress through making the bath bombs, you may need to spray the mix with rubbing alcohol to moisten them, so continues to bind together. If you live in a very dry climate, see my pro tip above.

  8. Allow the bath bombs to dry a minimum of 24 hours. My rule of thumb is that when it is hard to the touch, they are ready for the final stageā€¦the glaze!

  9. Place soap cubes into a microwave safe bowl and melt for 30 seconds and stir. Continue to melt in 30 second intervals until completely melted. You can add some glitter here or wait for the glazing stage.

  10. Using a condiment bottle or spoon, drizzle the soap over the bombs to give them the effect of icicles. If sprinkling the glitter, do it before the soap glaze hardens.

  11. Let set overnight before wrapping or packing in an airtight container.
