Craft Notes and tips

While the process to make ​​Rainbow Bath Bombs is simple enough, I appreciate that any helpful notes and tips would be beneficial. So here are some of the craft notes and tips that could help:

  • 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 then make sure they are supervised at all times. The last thing you want is them putting their fingers in their mouths if they have touched any of the ingredients you are using.
  • If you are struggling to find some of these supplies in your local shop then searching online is a great place to start. You will likely find all of these ingredients on platforms like Amazon.

Variations you could try

Like with any craft or thing that you create there will always be variations that you can try. After all, you can really make these your own and more personal if they are being made for gifts. So here are some of the variations you could try when making Rainbow Bath Bombs:

  • If you don’t like the idea of a rainbow theme then stick with a couple of colors. You could alternate two colors for a lovely striped effect, or even keep the bath bombs one solid color and focus on other aspects.
  • You could add some glitter to the bath bombs but bear in mind that this will then transfer onto you and the bath. The best advice would be to not go overboard with it.
  • If you want a different scent then you could use essential oils instead. You could make a purple-themed bath bomb and use a lavender scent, for example. Or citrus colors and use a lemon-scented oil instead.
  • Buy different shaped molds if you are looking to create something a bit different.

Frequently Asked Questions

There will always be questions, and so hopefully I will have covered them here for you. However, if I haven’t managed to answer a question you have, then please leave a comment or get in touch so that I can help.
