How not to make a bath bomb

How not to make a bath bomb

My bath bomb fail started out one weekday morning. My kids and I set up to try out a bath bomb recipe we found online, straight from the company who made the molds. I picked up all of the ingredients from the supermarket and set to work. We even used food coloring as it suggested and made, what would have been, some pretty creative bath bombs.

Where it all went wrong

In the bath bomb kit we have, there are 3 different size molds. However, in order to make multiple bombs of the same size, you have to take the bomb out out of the mold before making another. I followed the instructions, packed the ingredients in, tapped the mold and revealed beautiful bombs.

After I glanced at the bath bombs a few minutes later, I noticed that they appeared to be getting larger. Almost a half hour later they had nearly completely fallen apart. I took the mix and re-packed it back into the mold. However, even though I tried to let one dry in the mold for a few hours, it expanded and collapsed again.

Total bath bomb failure.

Bath bomb recipe (if you don’t want your bath bombs to hold together)

Ingredients (from the company)

1 cup baking soda
1/2 cup citric acid
1/2 cup epsom salts
1 tsp. water
2 tsp. essential oil or fragrance oil (avoid minty oils)
3 tsp. olive oil or similar vegetable oil
a few drops food coloring (any color)

My suggestion

I’m working on getting this right! I did order a set of 12 bath bomb molds so I can encase these and allow them to dry longer. Apparently, this mix is too oily and too wet and missing some key ingredients. In addition, I’ve received a lot of feedback about what to change in the recipe and plan on taking another go at this soon. I will post updates for you!

I do plan on getting this right!

I pinned your post. I have a whole ton of bath bomb recipes saved over on Pinterest with the intention of trying to make some of them one of these days. I have a feeling I’ll be having some epic failures of my own to laugh about one of these days. Looking forward to your update so I’ll have a clud when I do go to make some. Thanks for sharing this!

This is so good to know! I’ve been wanting to try my hand at bath bombs and have a feeling it may not go so smoothly at first, either.

This is very informative and pretty disappointing that a recipe straight from the makers of the molds failed so miserably! Thank you so much for sharing though, I look forward to reading your update!
