Step 1. You will need a small bowl to combine the bath bomb ingredients. Pour in the citric acid and baking soda and stir together using your whisk. Once you’re happy with the mixture, grab your pipette and fill with water.

Step 2. Squeeze a little bit of water out at a time. Mix quickly to avoid the dry mixture from fizzing up. You want to add in the water until the dry ingredients are the consistency of wet sand.

Step 3. Now add 3 drops of blue food coloring into the liquid mixture.

Step 4. Mix until it’s combined into all of the bath bomb mixture.

Step 5. Now it’s time to fill the molds. Use a spoon and add the mixture into your molds. Be sure to pat it down firmly. Allow to dry for at least 2 hours before removing from molds.

Step 6. Once removed, store in an airtight container in your bathroom and use at bath time.
