### Ingredients:
1. **Dry Ingredients:**
- 1 cup baking soda
- 1/2 cup citric acid
- 1/2 cup Epsom salt
- 1/2 cup cornstarch or arrowroot powder (optional, for a smoother feel)
- Bath bomb colorant (optional)
- Dried herbs or flower petals (optional, for decoration)
2. **Wet Ingredients:**
- 2-3 tablespoons of carrier oil (such as coconut oil, almond oil, or olive oil)
- 1-2 teaspoons of water or witch hazel
- Essential oils for fragrance (about 20-30 drops)
### Equipment:
- Bath bomb molds
- Mixing bowls
- Whisk
- Spray bottle (if using water/witch hazel)
- Measuring cups/spoons
### Instructions:
1. **Prepare Your Work Area:**
- Set up your work area with all the necessary ingredients and equipment. Make sure your molds are clean and dry.
2. **Mix Dry Ingredients:**
- In a mixing bowl, combine the baking soda, citric acid, Epsom salt, and cornstarch/arrowroot powder. Mix well until thoroughly combined.
3. **Add Color and Scent:**
- If you want to color your bath bombs, add a few drops of bath bomb colorant to the dry mixture and mix until evenly distributed.
- Add your chosen essential oils to the mixture and mix well. Make sure to mix thoroughly to evenly distribute the scent.
4. **Add Wet Ingredients:**
- Slowly add the carrier oil to the dry mixture, a little at a time, while continuously mixing. The mixture should have a crumbly texture and hold its shape when squeezed in your hand.
- If the mixture is too dry, you can add water or witch hazel using a spray bottle, a little at a time, until the desired consistency is reached. Be careful not to add too much liquid, as this can cause the bath bombs to activate prematurely.
5. **Fill the Molds:**
- Pack the mixture tightly into each half of the bath bomb mold, overfilling slightly.
- Press the two halves of the mold together firmly, then gently twist to remove excess mixture.
6. **Let Them Set:**
- Carefully remove the bath bombs from the molds and place them on a flat surface to dry and harden. This process usually takes 24-48 hours, depending on the humidity levels in your area.
7. **Enjoy Your Bath Bombs:**
- Once dry, your bath bombs are ready to use! Simply drop one into a warm bath and watch it fizz and dissolve, releasing its color, scent, and moisturizing oils into the water.
8. **Storage:**
- Store your bath bombs in an airtight container or bag away from moisture and humidity until ready to use.
With these simple steps, you can create your own customized bath bombs using a bath bomb mold, perfect for pampering yourself or giving as gifts to friends and family. Enjoy your luxurious bath time experience!
