Mix the dry ingredients together. If any are coarse, you can pulverize them in a coffee grinder. Optionally add in some dried rose petals to make them pretty for Valentine's Day. Keep in mind, though, that anything solid that you add to them will end up floating in your bath water. So if you don't want to be bathing yourself with bits of rose petals, don't add them in.
Once the dry ingredients are mixed, work in the oil(s). If using coconut oil when it's in its solid form, you can either melt it first or work it into the dry ingredients much like you would work butter into a pie crust.
At this point, the mixture should have the consistency of slightly wet sand. It should slightly hold its shape when you press it together.
Have your molds ready and nearby because once you start adding in your liquid, you'll want to work quickly.
Spritz in the water with a spray bottle, adding a very little bit at a time. Mix it in well after each addition. It will slightly fizz, and that is OK, but you want to try to minimize the amount of fizzing by not adding too much water at a time and by working it in quickly.
Once the mixture holds its shape when you clump it together in your hand, you can press it into the molds. Make sure to press your ingredients in firmly, trying to squeeze out any air bubbles.
Allow the fizzies to dry for several hours or overnight.
Carefully pop them out of their molds.
You can use them immediately or store them in a dry, airtight container until ready to use them.
If you want light pink fizzies, try adding some food coloring or beet juice into the water. For more vibrant colors, there are powdered pigments available that are specifically made for bath bombs. (They tend to be a less natural option.) I decided to rely on the subtle pink color of the Himalayan salt that I used as my only source of coloring.If you want to add fragrance to your fizzies and bath water, add a few drops of essential oils. (In this case, for rose themed bath bombs, a rose oil would be ideal, but it's an oil that is on the expensive side and is totally optional.)As you can probably tell, this recipe is highly adaptable. You can use pretty much any oil in place of the coconut oil. Keep in mind that some oils have a scent that may overpower the fragrance of your bath bombs. For my molds, I used silicone candy molds, ice cube trays, and muffin tins. Bath bombs molds are usually solid and made of metal or hard plastic. The advantage to that is that you can more easily fully compact the ingredients into rigid molds.There was no need to prepare the trays in any way.I don't recommend trying to dry them more quickly in the oven, even at the lowest setting, because they will likely fizz and expand rather than dry. (Don't ask me how I know that!)
