A sure way to impress your friends and family is by making them a homemade bath bomb. Seriously! I got so many oohs and ahhs after making this DIY at home and absolutely loved giving them away. My mom and mother-in-law didn't hate it either. Interesting fact, for those of you that don't know… I majored in chemistry for an entire semester… 😉 So I kinda didn't hate feeling like a scientist putting together this recipe. Major throwback!
In all seriousness, this is a really fun project to do during the weekend, or if you're really wild… on a week night! 😉 There are so many beautiful combinations you can make with the colors, and they make beautiful gifts… or just a prize for yourself at the end of a long week. Hello, me time!
I also recommend checking out Emma's bath bomb video. This gives you a great visual of the entire process! For this DIY, we have some slight variations and play with pigment/color, but I definitely suggest watching before starting the project.
Ready?? Let's do this!
-4oz. baking soda
-2oz. corn starch
-2oz. citric acid
-2oz. epsom salt (I used one that already had some essential oils in it, and it smelled divine!)
-1 1/2 teaspoons water
–essential oils (In addition to the epsom salt, I also used wild orange essential oil.)
-1 1/4 teaspoons coconut oil
–gold lustre dust
–plastic ball ornament (to use as the mold)
I first want to note that I used the above amounts for each color I created. I made four colors for my bath bombs, so you'll want to make sure you have quadruple (or more!) of your ingredients depending on how many colors you make for your bath bombs. If following this recipe and doing four colors, you'll be able to make 6-8 bath bombs.
Step One: Carefully measure and combine all dry ingredients into one bowl. Baking soda, corn starch, citric acid and epsom salt. Mix together and set aside. Do make sure your measurements are pretty exact. I used a scale to measure everything out, and it made things much easier!
Step Two: In a separate bowl, combine your wet ingredients. Water, essential oils, coconut oil and food coloring. For the essential oils on top of the already scented epsom salt, I added about 10 drops of wild orange to each batch I made for each color. For the food coloring, I kinda eyeballed it until I got the desired color. I wanted these to be more of a jewel tone and make my bath water super colorful, so I added a lot more than I usually would. I suggest starting with 10 drops and going from there if you are looking for a more vibrant bath bomb. Mix all your wet ingredients together and set aside.
Step Three: Now for the fun part. Again, if you haven't watched Emma's video, check it out… it really helps clear up this step. Little by little you are going to add the wet ingredients into the dry ingredients. As you add in the wet ingredients, your mixture might start fizzing. We want as little fizz as possible, so be sure to add in your ingredients drops at a time and stir. Towards the end of adding your wet ingredients, I suggest using your hand to really mix everything together and make sure the consistency isn't too dry. If it's too dry, you'll have issues with your bath bomb potentially crumbling or breaking. An easy fix is to add in just a sprinkle of water until it holds together when squeezed. Set aside your mixture and repeat steps 1-3 per color you wish to add to your bath bomb. For this recipe, I did four colors.
Step Four: Once all of your colors/mixtures are complete, it's time to add everything to your mold. I sprinkled a pinch of gold lustre dust to the bottom of my mold before adding in the mixture to give it a little shimmer and sparkle. Just make sure your lustre dust is food grade. Mine was originally meant for cake decorating and worked beautifully. After the dust, start to layer in your colors. I used a spoon to add in the mixture and pack everything in. I suggest using your fingers to make sure everything is packed in too. Slightly overfill each side before putting them together and closing the mold.
Step Five: I let some of my bath bombs stay in their molds overnight and noticed that after they dried and expanded a little, they cracked the plastic mold. So I would suggest very carefully taking off one side of your mold after it dries for a few minutes. Finally, let your bath bombs sit overnight. Again, carefully remove the remainder of the mold the next day. If your bath bomb falls apart, you can put it back into a mixing bowl and add a little more water to try again. ;)
Step Six: Wrap in colorful tin foil or store in a glass jar to keep it safe for giving or using in your own bath. Enjoy!
Please note, since we used a lot of coloring in these, I suggest doing a quick rinse out after taking your bath to prevent any staining.
Have fun mixing colors and making your own rainbow bath bombs! Lots of love, Sav.
