Bath bombs are all the rage right now. The hard-packed spheres are added to bath water to add oils, salts, fragrance, and delightful fizzies. You can buy high end bath bombs from a variety of sources, but they are simple (and much more affordable) to make yourself. I am going to be sharing a few different versions of homemade bath bombs this week, starting with these basic strawberry bath bombs.
Bath bombs are made from 4 dry ingredients. This recipe uses them in equal parts: 1 part epsom salt, 1 part corn starch, 1 part baking soda, and 1 part citric acid. To that dry mixture, you can add scent and oils as desired. I will link to the supplies I used at the bottom of the post.
This photo shows a 1/4 cup measuring cup, but I found that 1/3 cup of each ingredient gave me what I needed to make two bombs. Stir the dry ingredients together to eliminate any clumping.
Add in any scent oils and coloring that you would like. I think old-fashioned food coloring would work better than the gel variety, but I couldn’t find it anywhere! I wasn’t able to get completely even color distribution with the gel coloring, but that doesn’t effect how the bomb colors the water in the long run.
Add moisture, either by adding oils or spritzing SMALL amounts of water into the mixture until it reaches the desired consistency. You want to be able to squeeze the mixture and have it just barely keep its shape.
Pack the mixture tightly into the two halves of your bath bomb mold.
Press the two halves together tightly, brushing away any excess mixture that comes out. Refrigerate for at least one hour.
Here’s where I keep it real. I made two of these bath bombs and put them in the fridge to harden. When I came back later, they had exploded all over the fridge drawer. Exploded bombs means that too much moisture was introduced into the dry mixture as I was making them. I made these bath bombs in our un-airconditioned sun room, and I have a feeling that the high humidity worked its way into the mixture. I redid the steps inside our house the next day with much better results.
Unmold the bath bombs and allow them to air dry for a day or two before packaging them up for gift giving or storage.
To use the bath bombs, fill up your tub as you normally would, get in, and then drop one bath bomb into the water. The bomb will fizz and bubble as it fills the water with color and the air with fragrance. Enjoy! Come back this week for more bath bomb projects!

I️ bought the same exact citric acid from Five Below for 5 dollars.

Hello was hoping for some help my wife has started to make bathbombs but after leaving them for 24 hours and then taking them out the moulds they just break in half without force was hoping you could maybe help explain as to why this is happening please would really appriciate it thankyou
It sounds like your mixture was too dry. Adjust the recipe by adding a bit more oil or a bit more water. Hope that helps!
