Gather all of the necessary equipment needed to create these rose and coconut milk bath bombs.
Measure and sift the baking soda, citric acid, and coconut milk powder, place them in a mixing bowl together, and stir the ingredients together.
Next, measure the castor oil and the almond oil and stir them together.
In a separate bowl measure the lavender fragrance oil and polysorbate 80 and combine and stir them together.
Pour all of the wet ingredients into the dry ingredients and start mixing the mixture with your gloved hands.
Once the mixture feels damp and can hold its form take half the mixture and put it into a separate bowl.
Now add several drops of fushia liquid coloring or mica into half of the mixture. Using your gloved hands mix the colorant into the bath bomb mixture.
Next, place several rose petals into the bottom of the mold.
Now begin filling half the mold with the bath bomb mixture and alternate between the two colors.
Fill the other half of the mold using the same alternating technique. Overfill the mold slightly.
Push both sides of the molds together and now gently pull the mold apart, revealing the round bath bomb.
Let dry for 24 hours before using.
