Bath bombs! It's nothing new. These bombs are easy to assemble and make lovely gifts to give away. They also smell great too. There's nothing quite calming than taking a warm bath to relax those tense muscles after a long, hard day at work or while you're on vacation. Bath bombs are an added bonus. Just drop one in and watch it fizz!
There are a variety of recipes and instructions on the Internet and how to make bath bombs, but they all have something in common: baking soda and citric acid. Those are the important ingredients to produce a bath bomb that fizzes. The reaction with the baking soda and citric acid when water is introduced creates carbon dioxide gas which causes those bubbles in the bath. With a basic understanding of the science behind bath bombs, we can now go into the recipe a little further. For more information about the science of bath bombs you can check out Sudsy Science.
Sudsy Science goes into more detail about specific ingredients, such as corn starch as a "filler", which I have decided not to use here. Corn starch slows down the reaction and dissolves slower in the bath. In this recipe, I have added epsom salt to help reduce inflammation and promote muscle relaxation . For moisturizing properties, I have opted for olive oil. You can replace olive oil with coconut oil. You will need to melt the coconut oil in the microwave or stove top prior to adding it into the mixture.
- 1 cup baking soda
- 1/2 cup epsom salt
- 1/2 cup citric acid
- 2 tsp olive oil
- 3 tsp water
- 4-5 drops of essential oil (optional)
- 1-3 drops of food colouring
- In a bowl, sift or whisk the dry ingredients together to remove clumps.
- Add olive oil, water, essential oil and a few drops of food colouring together in a small container.
- Using a dropper, slowly add a few drops of the wet liquid mixture into the dry mixture, whisking as you go. Try not add too much liquid at one time to the dry mixture to avoid fizzing and foaming. If it does start to fizz, use the back of a clean spoon and quickly push down on that area to stop the fizzing and mix in the damp spot with the rest of the ingredients in the bowl. Continue mixing until the ingredients just come together. You know the mixture will be done when you take a small amount in your hand and squeeze it together. It should hold on its own fairly well. If the mixture is crumbly or too powdery, continue adding a little bit more water until it just holds.
- Trays - Pour the mixture into a tray mold and press firmly. Mixture can be packed into the tray.
- Molds - Fill each half of the mold with the mixture until it's overflowing a little bit. Press together and gently tap the mold to release.
- Allow bath bombs to dry overnight for at least 8 hours. Once dried, you can use them immediately or wrap them as gifts.
Other fun decoration ideas with bath bombs are using dried flowers or sugar decorations. Simply add the sugar decoration or dried flowers into the mold and pack with the bath bomb mixture.
Adding colour to the salt can also create a beautiful effect. Use coarse salt or sea salt and add a few drops of food colouring and mix well. Allow the salt to dry overnight before use. Use this salt in the mixture or use it as a decorative piece by adding a bit of coloured salt into the mold before packing it in with the bath bomb mixture.
For a fun gradient effect, divide the mixture and add food colouring after. Simply add a bit of each coloured mixture into the mold to create your desired colour scheme.
These bath bombs are a blend of ylang ylang, bergamot and lemon essential oils. This combination releases a delicate sweet, citrus and floral scent in the bath. These aromas are suppose to be soothing, relaxing and uplifting for the body. For more information about essential oil benefits and blending guide you can check out aromaweb.
Have fun making bath bombs! The possibilities are endless!
