There are a number of recipes for bath bombs online, and I’m not sure I’ve found the best one yet but I’ll share the recipe we followed for our first try. It was a lot of fun making them. Sophia Sunshine (the assumed name for an irl friend) was in town to help.
- 1 cup Baking Soda
- 1/2 cup Citric Acid (easily found at the health food store in bulk)
- 1/2 cup Corn Starch
- 1/2 cup Epson Salts
- 3/4 tbsp Water
- 2 1/2 tbsp Almond Oil
- A few drops Essential Oil (bergamot this time)
- A few drops Colour (3 drops red food colouring this time)
- Mix dry ingredients together thoroughly so there aren’t any lumps. We used a pestle to really combine it.
- Combine the wet ingredients in a jar by shaking them up together.
- Add wet to dry slowly and mixing while doing it. If the mixture starts to foam, stir that part around with more dry. You want the mixture to combine enough to lump in your hand if you squeeze it.
- Mold fairly quickly. You can buy plastic ornament mold things somewhere, I’m sure. Small or regular sized muffin tins also work. I used what I had on hand which was some small containers. They worked quite well to make many kid sized bombs. We packed the mixture in tight and then knocked out the molded bombs immediately to let them dry on a cookie sheet.
Eta. After all that, I only just now realised that Krista shared a recipe on her blog for the ones she made and it has a far far superior ingredient list. Having also tried her bath bombs, I know this is the recipe I’ll try next time.
