Get festive with these easy peppermint-scented DIY Christmas Bath Bombs!
Start by mixing together the baking soda, epsom salt, cornstarch, and citric acid. Divide mixture into two bowls. Add 2 scoops of red mica colorant to one of the bowls and mix well.
Add 1 tbsp of coconut oil and 10 drops of peppermint essential oil to each bowl. Mix well. Make a well in the center of each bowl and add 1 tbsp of water. Mix slowly, using your hands if necessary, to mix everything together, until it’s the consistency of wet sand.
The mixture should start holding together. If it’s not, add a little more coconut oil.
Layer the red and white mixture in each half of the bath bomb mold. Slightly over-fill each half, then press the halves together firmly.
Set bath bomb aside and let rest 15 – 20 minutes. Lightly tap the sides of the mold with a spoon, then gently remove mold. Let the bath bombs sit for 24 hours, before transferring to a clean, dry container.
Bath bombs will last up to 6 months, if stored in a dry environment.
