DIY Bath Bomb Recipe and Tutorial!

Hi friends!  My girls and I had such fun making these for gifts this year. It is a fun craft to make with the kids and you can even teach them about chemical reactions so it’s art and science all in one project!

Watch the video to see how! I’ll post the recipe below:)

Supplies & Recipe (with affiliate links to amazon BUT please note that everything EXCEPT citric acid and fragrance will be cheaper from your local grocery store, I want my peeps to get good deals!)

*Dry ingredients-whisk together in a bowl.
1 cup Baking Soda
1/2 cup Citric Acid
1/2 cup Epsom Salts
1/2 cup Corn Starch

*Wet ingredients Put in a small jar and shake
1 Tablespoon water
1 Tablespoon mineral oil (you can use melted coconut oil, soybean or olive oil but I chose mineral/baby oil as it will not turn rancid which is not an issue if you are using the bath bombs soon)
1 teaspoon of fragrance oil (I used one tsp or 3 droppers full but other recipes called for 6 which seemed like a lot. Use your own tastes and judgement)
Liquid food coloring as desired)
Bath bomb moulds 

Directions:
1. Whisk dry ingredients together. Slowly add the freshly shaken wet ingredients to the dry and combine with a whisk until there are no big lumps and it looks like sand.

2. Overfill both halves of your mold and press together firmly. You can use other moulds you have as well but you need to pack the mixture in very tightly or the bath bomb might crumble when you remove it from the mold.

3. Remove the bath bomb from the mold and set in a tray/box lined with plastic wrap to dry for 48 hours.

4. After 48 hours wrap with plastic wrap and blast with a hairdryer for a professional look. You can also add in dry pressed flowers when you warp them for a beautiful presentation.

Want a side of science with your art?

Why does it fizz? The citric acid is an acid and it reacts with baking soda (a base) just like vinegar and baking soda does. The bombs are quiet until water activates the citric acid and the reaction begins. The bubbles that are created are carbon dioxide. The corn starch serves two purposes: 1. it acts as a filler and a buffering agent between the citric acid and baking soda so you get a “slow fizz” rather than an explosion and 2. it is a binder and helps the bath bomb hold it’s rock hard shape until dunked in water.

The remaining ingredients are therapeutic!
Epsom salts will soothe sore muscles and soften skin
The oils smell nice and will moisturizer skin and the food color is pretty.

I had a lot of requests to post this tutorial after sharing photos of the bath bombs we were making. I hope you have as much fun making this as we did! Happy crafting!
