Add the 1 1/2 cups of baking soda into a dry bowl.
Then add the 1/2 cup of citric acid powder into the same bowl as the baking soda and mix them together.
In a separate bowl for wet ingredients mix together the sweet almond oil, with the essential oil, and food coloring.
Pour your wet ingredients into your dry ingredient bowl and start mixing immediately.
Repeat steps 3 and 4 until mixture is at desired texture.
Mix in optional dried flower petals or glitter.
Once the mixture is at the desired texture, spoon parts out into a mold, can be any shape.
Press mixture down into molds.
Let mixture sit in molds for 24-36 hours.
Now pop your bath-bombs out of their molds and either display them or use them right away.
