This is such a fun project! This recipe is different, because it uses oil for the liquid instead of water or witch hazel. When you use water or witch hazel, it makes them tricky to make, because you have to get the amount just right. The oil is much easier to use.
You could add a colorant to these, such as beet powder (get it here). Also, instead of using plain oil, you could use some herbal infused oil! For essential oils, again do not use cinnamon, clove, or any other “hot” oils. I recommend Lavender, Peppermint, Geranium, or small amounts of Orange.
Note: Please be careful when getting out of the tub, because the oil can make the bathtub slippery. It may be a good idea to put a dishtowel at the bottom of the tub to provide some traction.
Recipe for DIY Fizzy Bath Bombs
2 parts baking soda (get it here)
1 part citric acid (get it here)
Oil (Sweet Almond, Olive, Sunflower, etc.)
5-10 drops essential oil (If using Peppermint, only use three drops)
Mix together the dry ingredients in a bowl. Slowly add oil until the mixture holds together when squeezed. Add the essential oils. Tightly pack the mixture into Silicone molds, or muffin tins with muffin liners in them. If using dried herbs, place them in the bottom of the mold before packing the bath bomb mixture into them. Let these dry for one week or until completely firm and dry.
Place 2-3 bath bombs into bath.
