DIY Fizzy Bath Bombs

Bath bombs are relatively easy to make but before you get started, make sure you have the ingredients and proper tools for this recipe. You may also choose to wear gloves if your skin is sensitive to baking soda or citric acid.

You’ll need a mixing bowl, whisk, molds (you can also use measuring cups), and a spray bottle to get started. You will also need two cups baking soda (aluminum-free is best), one cup citric acid, one tablespoon coconut milk powder (learn all about coconut milk powder here), two tablespoons coconut oil, and your favorite essential oils and herbs.

Step 1

Mix the baking soda, citric acid, and coconut milk powder together in a large bowl. Use your fingers to squeeze out any clumps.

Step 2

In a separate small bowl, mix the coconut oil with the essential oil. Drizzle the liquid mixture into the combined dry ingredients while stirring with a whisk.

Break up any remaining clumps with your hands and make sure the mixture is completely incorporated.The mix will feel like wet sand.

Step 3

Squeeze a portion of the bath bomb mixture into a ball shape with your hands. If it crumbles, spray 3-5 spritzes of witch hazel into the mixture while stirring, then check again. When the mixture holds together easily without crumbling, it’s ready.

Spoon the mixture into bath bomb molds, pressing firmly as you pack it in. You can add herbs, lavender, or rosebuds to the bottom of the molds. Turn the bath bomb from the molds and onto a sheet of wax or parchment paper.

Step 4

Allow them to air-dry for several hours, then wrap in airtight packaging. You can use plastic wrap or store them in an airtight container.

If you want to test the mixture before letting the bath bombs set, you can adda small amount of it to warm bath water. The mixture will bubble and fizz!

How do I add color to these bath bombs? 

You can create different colors when making your own diy bath bombs by adding dye or natural ingredients.

I love to use spirulina to make green/blue colored bath bombs, and beet root powder to make pink/red tinted bath bombs. You can also add natural food coloring to dye your bath bombs or mica powder to add a shimmer. Add the dry colorants to the dry ingredients before mixing. If you’re using liquid color, add it to the wet ingredients while making these bombs.

Is citric acid safe to use?

When I looked into making my own bath bombs I was a little worried about working with citric acid. I know that citric acid was the ingredient that caused bath bombs to fizz, so I wanted to be careful about working with it. It turns out that citric acid is a natural compound that can be derived from citrus juice (primarily lemon juice) but it can be derived from sugar cane and cassava. It’s the main ingredient in this easy DIY bath bomb recipe and creates the fizzy reaction in bath bombs. When citric acid is added to water, a chemical reaction occurs with the baking soda to produce carbon dioxide gas, which disperses throughout the water and creates the suds. If you’re looking for a cool science project to do with kids, this is a really fun one!
