DIY Bath Bombs

I picked up my first bath bomb at a general store in new Hampshire about 2 years ago. I didn’t really know what it was at the time, but I was big into baths so it seems like a great idea. I’ve used a few since then, and after looking them up online they seemed like a fun project for a cold day. I sifted through several recipes before realizing I could make my own combination and they would probably turn out ok. Here’s what I did:




– 1/2 cup backing soda
– 1/4 cup citric acid
– 1/4 cup corn starch
– 1/2 cup Epsom salt
– fragrance oil
– witch hazel in a spray bottle
– coloring. I added a few drops in with the witch hazel
– a bowl and spoon to mix
– molds


Let’s get started!

1) Combine those try ingredients and mix well.


2) Start spritzing in the witch hazel while continuing to mix! Do this until it starts clumping.


You want the mixture to just start clumping together. The wetter it is, the longer it will take to dry out. Also, if your mixture is too damp you run the risk of activating the baking soda, and then they won’t fizz in the bath!


3) Add fragrance oil to smell. Some recipes call for 2 tablespoons, some call for a few drops. I wanted them to be scented but not overwhelming, so I used about 10 drops.

4) Mold them! Pack the mixture in nice and tight.


5) Let sit for a couple minutes before popping them out. I did NOT do this with the Lego molds and all but one lost their heads :(


6) Wait several hours for them to dry completely. You’ll know they’re ready to use when they don’t have any play left when you give them a little squeeze.


I made tiny ones with ice cube molds I had on hand, so I need a handful for a bath. But I like them! And because they’re small, it’s easy to mix and match scents :)
