Tips for Making Bath Bombs

If the bath bomb mixture will not hold together in your hands, add 1/2 teaspoon of binder (oil, alcohol, witch hazel, or water). This should take care of the issue.
If you have the opposite problem and your bath bombs have too much liquid, add 1/2 teaspoon of baking soda or cornstarch. Continue to add 1/2 teaspoon until the mixture feels like wet sand.
As you make several bath bombs, the mixture will likely dry out. Use a spray bottle with a binder and give the mixture a few spritzes to add the amount of moisture needed to hold the bath bombs together.

Notes for Making Hidden Toy Bath Bombs

If you don’t have a rubber duck for the hidden small toy in the bath bombs, use a child’s costume ring or a small bouncy ball.
In addition to the traditional round bath bomb molds, you can also use silicone mold typically used for making soap. Just press the mixture, let it rest for a couple of hours in the mold, then de-mold and let it rest again to dry.
Pack bath bomb molds tightly but not compressed, as they may not release as easily as they should. If yours isn’t releasing, let it sit for an hour to dry a bit. Tap the outer edges of the bath bomb mold with the back of a spoon.
