Step 1
To make a basic Bath Bomb you’ll need the following dry ingredients:

1 cup baking soda
1/2 cup fine citric acid
1/2 cup corn starch
1/2 cup fine Epsom salt (optional)

Use a small food processor to grind coarse ingredients.
Step 2
In a spray bottle mix:

2 1/2 Tablespoons of Sweet Almond Oil
3/4 Tablespoon water and liquid glycerin
1/2 teaspoon of Essential Oil
1/4 teaspoon of Borax
Step 3
Thoroughly combine dry ingredients into a large bowl.

Stir the remaining ingredients in small measuring cup, if desired add colorant to the mix. Pour wet ingredients into spray bottle and shake to mix.
Step 4
This is the crucial stage in the creation of a bath bomb: mist dry ingredients to moisten, applying too much moisture will start the fizzy reaction.
Step 5
Moisten mixture enough to look and feel like wet sand, so when worked with it holds a shape.
Step 6
Press mix into one half of the mold, repeat with other half, place more of the mix between the halves and press together. Wait a few minutes and without twisting gently remove one half of the mold. Turn the mold over, allow bomb to pop out of the mold.
Step 7
Place on a kitchen towel and allow to dry overnight and possibly several days. If the air is humid, a fan helps to dry bomb. Once dry, wrap bomb in tissue paper. Crush dud bombs that fall apart while drying and give as fizzy bath salts.
Step 8
The Bath Bomb is great gift and while it takes time to make, the result is a blast. Citric acid is the ingredient that causes the fizzing. Use finely ground citric acid to make a successful bomb.
