Ask my husband and he will confirm my favorite thing to do every day (sometimes on cold days more than once) is take a nice warm bath. Every evening before bed I soak, read, and give Forrest time to play his football video game thing. It is no wonder why I love making my own bath bombs. It is cheaper than buying them at fancy stores and you can control what is in them. For instance, a little extra oil if you have dry skin, or what kind of scent and how much.
Here is how to make them:
You will need baking soda, citric acid, corn starch, Epsom salt, a light oil (I use EVOO but other people use different kinds), your favorite essential oil (scent), and water. For this batch I used Rosemary Oil which smells just like Vick's Vapor Rub in the bathtub....mmmMMMmmm!
Just mix 1/2 C of the baking soda with 1/4 C of the citric acid, corn starch, and Epsom salt. Stir a bit and add about a tablespoon or so of the olive oil and as much of the essential oil as you enjoy (should be within about 1/2-1 tablespoons worth of drops). Mix this around and create a well in the center where you should put about 1/2 tablespoon of water and then mix it all very quickly before the water fizzes the powder too much.
Use a tablespoon sized mold (I just used an actual tablespoon) and scoop up a mound of the mixture and press it firmly in the mold with the heel of your hand.
Tap the mold onto the palm of your hand gently to release the bomb and carefully place on a dry surface. They will be very breakable at this point, but if they cant even be handled gently then go back and add another 1/2 tablespoon of water. You should end up with 14-16 bombs if they are a tablespoon each.
Leave them out for at least several hours or overnight to dry and firm up, and then place them in a cute watertight jar to set next to your tub!
