Put all of your dry ingredients into your mixing bowl and mix until well combined, being careful to make sure no clumps remain.
Pour the almond oil, essential oils and witch hazel into a small glass mixing bowl, then whisk until combined. Gently, pour the liquid mixture into the larger bowl with the dry ingredients.
The mixture will start fizzing as soon as the liquid touches the dry ingredients.
Mix with a fork (or your hands) until everything looks like it's well combined and somewhat moist.
Prepare your bath bomb molds and use a spoon to fill the molds halfway. Using a silicone spatula, press the mixture into the molds firmly.
Spray each mold with a small bit of water (one spray) and press down again to make sure they're firm. Using too much water will cause the bombs to lose their fizz (and start growing out of control). If you don't press down firmly enough, the bath bombs will not hold together.
Divide the remaining mixture into the molds and again press down firmly. Spray the top with water and press down again.
Close the molds, and allow them to sit on the counter for twenty four hours to set before removing from molds.
Due to the mica powder and almond oil, these bombs will leave your bath a bit slippery. So take caution when you're getting out!
