Ingredients for Your Bath Bombs
The ingredients below are all the basics you will need to make your homemade bath bombs.
Once you have practiced making the bath bombs a few times you can experiment by adding a few other natural ingredients to your bath bomb mixture such as sea salt, grapeseed oil, olive oil, melted coconut oil and shea butter.
These other optional ingredients can all help to create a relaxing bath experience and may assist with certain skin conditions such as eczema.
You may also wish to use essential oil or fragrance in your bath bombs but this is optional. There are some great options available that are gentle on a child’s skin. My favourite is the lavender essential oil by Fuse which is available on Amazon.

Directions to Make Your Bath Bombs
1. Combine the Ingredients
Pour the the citric acid, Epsom salt and baking soda into a large bowl and stir. Make sure all the dry ingredients are mixed well together. At this stage the ingredients are all in a powder as shown in the photograph below.

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 dry 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.
If you want to add some essential oils that are safe for children this lavender oil is suitable for sensitive skin. Lavender essential oil is great for creating a soothing bath. Add 15 drops of the oil to the dry ingredients.
Tip: Make sure you use a bath bomb colorant and not food coloring 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. If you want to make your DIY bath bombs into fun shapes you can find a selection of bath bomb mold ideas for children below!
If you want to put surprise toys inside your bath bombs this is the time to put them into the mold along with your ingredients. A small toy inside your homemade bath bombs makes bath time fun!

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

6. Final Result

How to Use Your Bath Bombs
Once you have made your bath bombs simply run a bath of warm water and drop your bath bomb in. Make sure to fill the bath before putting the bath bomb in to ensure it dissolves properly.
As bath bombs can irritate the skin if used too often, I would recommend to not using them more than once a week.
What Makes Bath Bombs Fizz?
The sodium bicarbonate (baking soda) and citric acid in your bath bomb create a chemical reaction when you put it in your bath water. It starts to make carbon dioxide which is what causes the fizzing reaction.
