Coloring(food coloring should be fine)
Fragrance oil (optional, I personally luv fruity fragrances!)
Different molds to make you're fizzing bath bombs fun and interesting!
1. Take your citric acid and baking soda and mix them very well.(This step is very important)
2. Add coloring and the fragrance oil of your choice to the batter and mix. Then spray the Astringent onto the batch while mixing it, continue to do so until it sticks together easily enough to make a mold.
4. Take parts of your mix out and place them into your molds or be a Picasso and mold them into different shapes by hand.( Note: Be sure to do this in a timely manner you do not want your batter to dry out before you are finished molding!)
