Add the dry ingredients (Baking Soda, Cornstarch, Epsom Salt, Citric Acid, and Dried Herbs) to a large mixing bowl.
Next, add the wet ingredients (Almond Oil, Essential Oils, Water).
Mix until you can squeeze the mixture in your hand without it crumbling, similar to the texture of sand.
Once the mixture has reached the right texture, pack it into the molds. I used silicone cupcake liners because it is what I already have on hand. If you want to use real bath bomb molds to make a sphere, check these out
Pack the mixture tightly into the mold, being sure not to overfill the molds as the mixture will get larger as it sits.
Let the herbal bath bombs sit out at room temperature for at least 12 hours. The bath bombs should be completely dry once they have been set.
When the herbal bath bombs are dry, take them out of the molds and store them in a container. Use as often as you please!
