Bath bombs are the bomb, but they are often expensive. And why spend a lot of money on something you can make at home?
These festive Grinch bath bombs make ideal stocking stuffers and are an incredible DIY project!
In a large bowl, combine the dry ingredients: citric acid, Epsom salt, baking soda, cornstarch, and matcha green tea powder.
In a medium bowl, add the essential oils by liberally drizzling in the coconut oil.
Gradually add the liquid ingredients to the dry ingredients, stirring constantly until the mixture is well combined (you want the mixture to feel like you could build a sandcastle with it — and the salts should clump together in your hands).
Note that whether you need to add water will depend on your climate. If needed add witch hazel or tea tree oil one spritz at a time until you reach the desired consistency.
A word of caution: Take care when adding liquid. If the mixture gets too wet, it can become reactive.
We used stainless steel bath bomb molds purchased from our favorite craft store, but they are also available on Amazon. The great thing about stainless steel molds is that they won’t dent, and you can use them over and over again. You can also use plastic Christmas ornaments as molds, which make great stocking stuffers.
Add a single heart sprinkle to one side of the mold and pack the mixture in tightly until you can level the surface using a ruler or your hands. The molds may require a bit of fiddling to get them to fit tightly together. Work your molds so they are not too full or not full enough. Both flat sides of the bath bomb should sit flush together (we taped our molds together so they wouldn’t accidentally pop open).
Allow the bath bomb to sit overnight. Since we’re in Atlanta, we’ll have to wait a little longer for them to fully heal.
Once ready, gently tap the outside of the mold with a spoon, and your Grinch bath bomb will pop out.
