Mix together the baking soda and the cornstarch in one bowl, and the
citric acid, almond oil, and distilled water in another. Find citric
acid, also known as sour salt, in natural-food stores, craft shops,
and some supermarkets.
If you want your bath bombs to foam, add 1/8
cup of sodium lauryl sulfoacetate to the dry mixture once you’ve
combined the other dry ingredients. Order it on the internet.
Lightly grease the molds with sweet almond oil. If you donít have multipurpose
craft molds, you can use muffin tins, ice-cube trays, plastic Easter
eggs that snap apart, or even Christmas ornament packages instead.
Combine wet and dry
Slowly add the wet ingredients to the dry ingredients, mixing them them
with your hands. If the mixture is too dry to stick together, mist it
with a little witch hazel, which you can find at drug stores.
Dried flower petals, the zest of lemons or
other citrus fruits, or food coloring can be added to the mix.
Press into molds
Press the mixture into molds, let them sit for a few hours, remove,
and let them dry for a week.
If youíre giving the bath bombs as gifts, cover them with colored plastic
wrap and tie with ribbon. Otherwise, cover them with tissue paper and
store in a cool, dry place.
