Storing the Geode Bath Bombs

To ensure that your Geode Bath Bombs remain of good quality, you want to avoid them being exposed to oxygen and moisture. So make sure you store them in an airtight container. Keep them upright so that they stay intact.

Tips and Tricks

  • If you want to add a scent, then you could add essential oils or fragrance oils.
  • Use different-shaped molds if you are looking to create something a bit different.
  • Add some glitter to the bath bombs but keep in mind that this will transfer onto you and the bath. My best advice would be to not go overboard with it.
  • Make sure you have all of your supplies to hand before starting this process. As some parts of the method require you to keep monitoring and stirring your mixture, it makes things much easier to ensure that you get it right.
  • If children are helping, make sure they are supervised at all times. The last thing you want is for them to put their fingers in their mouths if they have touched any of the ingredients you are using.
  • If you struggle to find some of these supplies in your local shop, searching online is a great place to start. You will likely find all of these ingredients on platforms like Amazon.
