You should be able to get most (if not all) of the ingredients for your bath bombs at the grocery store. You'll need:
- 1 cup cornstarch
- 1 cup citric acid (Buy Direct)
- 2 cups baking soda
- 1/2 cup epsom salt
- 1/2 cup sea salt
- 2 tsp. water (I use distilled)
- 1/2 tsp. borax
- 1-2 tsp. essential or fragrance oil
- 2 tbsp. of a light oil like jojoba, grapeseed, fractionated coconut, or rice bran
- optional a few drops of a soap safe dye colorant (Yes, you can use food coloring, but if you can get real soap colorant, you'll use less and it will not fade as quickly.) I like them just plain white. I cover coloring your bath bombs in Coloring Your Fizzy Bath Bombs
Equipment
Like the ingredients, the equipment is pretty simple too.
- a big mixing bowl
- a whisk or mixer with whisk attachment
- measuring cups and spoons
- something to mix the "wet phase" in - I prefer a small squirt bottle like you use to make small chocolate treats. You could use a small lotion bottle, a hair dye bottle, or any other small bottle that will allow you to squirt small amounts of liquid into the dry ingredients. If you don't have a squirt bottle, a small ramekin, creamer or small gravy boat will do.
- a sieve or sifter
- a spoon or two
- a spray bottle with distilled water in it
- a mold for the bombs (we'll talk a little more about this later)
- a cookie sheet with paper towels for the bombs to dry on
