To make bath bombs, you need 1 part citric acid and 2 parts baking soda, witch hazel in a spritzer bottle, color (dried pigment or La Bomb colorant), fragrance 0.5 oz for 2 pounds, and a mold. In this example, I used cellini blue mica, ocean blue jojoba beads, and Celestial Waters fragrance.
Once the baking soda and citric acid have been thoroughly mixed together and you have added color, spritz with witch hazel as you mix until it holds its shape when you squeeze the mixture.
To create the 3D bomb, fill both sides and compact it really well (the harder you compact it into the mold, the denser and longer-lasting the fizzy), then overfill both sides and push them together. Let them harden in the mold for ten minutes or so before setting it on the table to avoid getting flat spots. That's it! Super easy and a great addition to your product line.
