Bath bombs are surprisingly easy to make. With a bit of practice getting the right consistency of the ingredients, you will be bathing in mentholated luxury in no time.

Watch this episode of DIY This With Jennifer Perkins with not only mentholated bath bombs but also a rose petal variation.


  • 1/2 cup cornstarch
  • 1/2 cup citric acid
  • 1 cup baking soda
  • 1/2 cup Epsom salt
  • 2 Tbs oil (coconut, almond or olive)
  • 1 Tbsp water
  • 10-15 drops peppermint essential oil
  • 10-15 drops eucalyptus essential oil
  • colorant (dry skin safe pigment, food coloring or soap coloring)
  • mixing bowls
  • bath bomb molds

Just as if you were baking, first sift and mix the dry ingredients in one bowl. In another bowl, mix the wet ingredients except for the essential oils and scent. TIP: Melt the coconut oil first if it has congealed.

Combine the mixtures slowly. You do not want to activate the citric acid. Knead the mixture together; using your hands works best. Divide the mixture into two bowls. In each bowl add the color and essential oils (orange bowl and blue bowl).  A color pigment that is safe for dry skin can also be used in place of food coloring. Knead the ingredients together. Wear gloves to prevent staining your hands.

When you can pack the mixtures together like wet sand, it is time to fill the mold. If your mixture is not sticking together, add a bit of water or witch hazel. One color at a time, layer scoops into each half of the mold. Make sure to compact each level tightly. Think of molding a sand castle.

Overstuff each side of the mold. This is the layer that will attach the two sides.

Join the two sides of the mold together and gently twist and tap. Squeeze until the two metal sides are almost touching. Do this over another bowl so you can catch and reuse the excess over-stuff that falls. Remove one side at a time. If your mixture crumbles when coming out of the mold, you can always start again with a bit more liquid (water or oil).

When you have created a batch of the bath bombs allow them to dry and harden for 24 (better yet 48) hours. Some people recommend placing them in the freezer to speed up this process.

To use your bath bomb, drop it into a full warm bath. The citric acid will activate and will bubble like soda water.  At this point, the oils for your skin are being released into the bathwater and the smell should be mentholated and strong helping to clear your sinuses. Soft skin and being able to breathe - a winter win-win.
