What Are Bath Bombs?
Bath bombs are soft-but-solid, roundish balls of materials designed to dissolve and bubble when they make contact with water. The bombs are placed in bathtubs after they have been filled with water, as with bubble baths. While dissolving, bath bombs can contribute scents, colors, oils, cleansing agents or other materials to the bath water. Bombs usually are composed of sodium bicarbonate (baking soda), citric acid or another organic acid, corn starch and magnesium sulfate (Epsom salts). All of these ingredients combine to create the fizzing and dissolving effects for which the bombs are known. The bombs might also contain materials such as food coloring, glitter, herbs or dried flowers for added effect.
