How to make Bath Bombs

Having been making lots of bath bombs and speaking to people I realise there is a lot of myth behind them. If you want to make some for christmas family, friends or for the school fete, they are quite simple.  I work with 100gm bicarbonate of soda and 50gm citric acid.  Always half of the citiric acid to the bicarb. The citric acid is much better the finer it is.  You mix these two together and this is the secret you need to mix them very well and when you have re-mix the more you mix these two the better.  Then add colour not too much as when the witch hazel is added the colour will intensify, also add at this point the fragrance/essential oil you want.  Then mix again, you can never mix too much.  Now with witch hazel in a spritz bottle you need to just put a few squirts and mix  mix mix.  The mixing is so important as you mix the witch hazel soaks into the ingredients and slowly makes them damper.  After a good bit of mixing see if you can squeeze the mix together like damp sand and it will stick, if it does, then mold it.  If not spritz again, not too much and then mix mix mix.  This should do the trick.  If like I used to get, you get your bath bomb growing spots like warts, then it was too wet and the fizzing process is starting, so mxing is the answer.
