Fizzy Bath Bomb Recipe

Bath bombs are a wonderful way to relax. And, they make a great gift idea for kids, tweens, teens, and adults.

Kids enjoy watching the bath bomb fizz when it’s added to the water. And, adults enjoy the relaxing scents and beneficial effect on their skin.

To put it at its simplest, a bath bomb is just a collection of dry ingredients, scents, and color (optional) that breaks apart when it’s added to bathwater. 

Depending on which recipe you use, the dry ingredients vary. Some are more or less natural depending on which tutorial you use. 

They can also be purchased if you don’t want to make your own. This variety is organic and natural so there are no worries about ingredients.

How do you make bath bombs?

To make bath bombs, you will need a few simple ingredients. First, you will need a bath bomb mold.

You can start with a small mold for smaller bath bombs or you can use a larger mold if you prefer a large bath bomb. This set has a variety of sizes along with some gift wrap and gift bags if you’d like to give them as gifts.

The full ingredient list for this recipe is below. You can print it out to make it easier to reference while you’re working.

How do you make fizzy bath bombs?

So, not all bath bombs are fizzy bath bombs. This recipe uses citric acid and bicarbonate of soda otherwise known as baking soda.

When the bath bombs are added to the water, it starts a chemical reaction between these two ingredients. If your bath bomb recipe does not include these two ingredients, it will not fizz.

How do you make Epsom salt fizzy bath bombs?

Again, not all bath bombs include Epsom salts. But, if you want to add them, this fizzy bath bomb recipe does use Epsom Salts.

You will need to be sure to add enough moisture (coconut oil) so that the ingredients hold together well.

Directions

  • In a large bowl, whisk together cornstarch, citric acid, salt, baking soda, and mica powder. If making more than one color, divide the mixture into separate bowls.
  • In a small measuring cup, whisk together essential oil, coconut oil, and water. Note: If making more than one color, divide the mixture into separate bowls.
  • Very slowly (to avoid as much fizzing as possible) add the water solution to the dry ingredients. Stir and mash together until it resembles sand.
  • Immediately transfer bath bomb mixture into bath bomb molds, pressing mixture tightly into each side and adding a little to overflow each side of the mold. Press the mold together, twisting until closed.
  • Allow bath bombs to rest (and dry) for at least 24 hours.
  • To remove the bath bombs from the molds, tap the outside of the mold gently. Then, twist each side of the mold and pull to remove the bath bomb.
  • To give as a gift, wrap tightly in plastic wrap or place in an airtight jar.
