Method
Make sure all your equipment is totally dry as any moisture will start the ingredients fizzing.
Sieve the baking soda and the citric acid together into a bowl and mix well.

Add the oils and the food colouring together in a second bowl.

Pour the oils into the bowl with the baking soda/ citric acid mix. Mix with your fingers very quickly. If you dont mix quickly the fizzing reaction may set off.

Mix quickly with your fingers


The mixture should be powdery but start to clump together if you squeeze it. Add a tiny bit more oil if needed.

The mixture should by powdery but clump when squeezed


Press the mixture into the ice cube molds. It's important that it is very hard packed to stop the finished bath bomb crumbling apart, so put in a spoonful at a time pressing it in very firmly with your fingers before adding another spoonful.

Add one to your bath and enjoy the fizz!

In humid or damp conditions, the finished bath bombs will quickly pick up moisture from the air and start to develop a bubbly surface. It's best to keep them in a dry airtight container and plan to use them within a few days.
