Bath Bombs for Kids

Ingredients to Make the Bath Bombs

1/4 Cup of Citric Acid

1 cup Epsom salt

Witch Hazel

Your Choice of Mold

2 1/2 cups baking soda

Bath Bomb Colourant

Mixing Bowl

Spray Bottle

You may also wish to use essential oil or fragrance in your bath bombs but this is optional.

How to Make the Bath Bombs

  • 1. Combine the Ingredients

    Pour the the citric acid, Epsom salt and baking soda in the bowl and stir. Make sure all the ingredients are mixed well together. At this stage the ingredients are all in a powder as shown in the photograph above.

  • 2. Mix in the Colorant and Fragrance

    The next stage is to add a few drops of the colorant and if you wish some essential oil or fragrance. Combine the mixture using your hands. Please note that the oil and colorant will cause the mixture to clump together, but it shouldn’t start to fizz.

    Tip: Make sure you use a bath bomb colorant as food coloring could stain your bathtub!

  • 3. Spray the Witch Hazel into the Mixture

    Add the witch hazel to the spray bottle and slowly spray the mixture while at the same time mixing it with your hands. You need to get the mixture to be moist enough to form into the molds, but not wet enough to start fizzing.

  • 4. Pack the Mixture into Your Chosen Mold

    As you spray the witch hazel onto the mixture you will feel it start to stick together. When this happens start to pack the mixture into the mold. (See below for a selection of bath bomb mold ideas for children!)

  • 5. Leave Overnight to Dry

    Leave the mixture inside the mold overnight to dry and then gently remove the bath bomb from the mold.
