Simple bath bombs

We joined our dear friends for a little trip to Shenandoah. For three days in a row, we did nothing but enjoying good company, good food, and good fun. We hiked and swam a lot in Shenandoah river, so let’s just say we deserved a very blissful bath once we got home. The kids decided to indulge themselves with… drum rolls please… DIY bath bombs. I’m all in!

Simple bath bombs

For 8 bath bombs, about 40 g each (picture above)

(Adapted from A beautiful mess and the Spruce Crafts)

120 g baking soda (about 1/2 cup)
60 g epsom salt (about 1/4 cup)
30 g cornstarch (about 1/4 cup)
60 g citric acid (about 1/4 cup)
10-15 drops of color of your choice
10-15 drops of essential oil of your choice
1 tbs coconut oil (or castor oil, or olive oil, etc.)
2-3 tsp water (add one tsp at a time)
Any mold you can find in your house (we used our cute boil egg molds just because!)

  1. In a large bowl, use a fork to combine all dry ingredients: baking soda + epsom salt + cornstarch + citric acid.
  2. Add color drops + essential oil drops + coconut oil. Use your fingers to mix until combine.
  3. Use a spray bottle to spray water into the mixture (or use a teaspoon to add 1 tsp of water at a time) until the mixture can hold into a tight clump.
    • Note: it is very important to avoid wet mixture, otherwise your bath bombs will not fizz. 
  4. Tightly pack the mixture into your bath bomb mold.
    • Note: you can press two molds together to make a ball, or two sides of a star, etc. Our kids got impatient so we left one side unfinished. Hey, it will be dropped in our bathtub any way. 
  5. Let your bath bombs dry over night.
  6. Enjoy!
    • Note: store your leftover in an air-tight container for up to 3 months.
