Bath bombs are great project for both beginner and advanced crafters. Making bath bombs is an easy process, but it takes practice. Bath bombs are sensitive to moisture and can be finicky. Without the right mixture of ingredients bath bombs can crumble, fall apart or fizz incorrectly. Below are some of the most common bath bomb questions we receive, along with links to other bath bomb posts!

Bath bombs consist of baking soda and citric acid. When these two ingredients are combined and introduced to water, they create a fizzing reaction. Click here to read more about baking soda. The standard ratio is 2 parts baking soda to 1 part citric acid. Once the dry ingredients are combined, a small amount of liquid is introduced to create a moldable, wet sand texture. The liquid is usually witch hazel, but oils and butters can also be added for moisture and additional skin benefits. The bath bomb mixture can be further customized with fragrance, color and the shape of the mold. Now, let’s get to the questions!

Why is my bath bomb crumbly or cracking?
If you find that your bath bomb is crumbly, the mixture may be too dry. Adding more witch hazel or oils will give the mixture a more moist texture, which will be less likely to crumble and crack once removed from the mold. If your fizzy is cracking after it’s been in the mold, it’s possible that it was too wet and the mixture is expanding as it sits in the mold.

Why is my bath bomb soft?
If your bath bomb is soft, the mixture may have too much moisture. If you add too much witch hazel or oil during the mixing process, add more dry ingredients to balance the texture. If you live in a humid, wet climate, the moisture in the air can prevent the bath bombs from becoming hard. Adding a small amount of clay (like kaolin clay) or cornstarch can help the bath bombs harden. They also make the bath bombs a bit more sturdy.
