Bath Bomb
What you need:
300g Bicarbonate of Soda
100g Citric Acid
10ml Fragrance or Essential Oil of your choice
Few drops of red food colouring
A large mixing bowl
Round moulds to shape the bath bombs
To make:
Into a mixing bowl add 300g Bicarbonate of Soda and 100g Citric
Acid.
Mix together. Add the colour a very small amount at a time and mix
in until you have the colour you require. Add the fragrance or
essential oil and mix in quickly. Test the mixture by squeezing some
in your hand. It should just hold together and not be too damp. If
too dry you can spray a little water onto it.
Then you need to work quickly to compress the mixture into your
moulds.
After about 30 minutes they should be quite hard. Simply take the
bath bomb from the mould and leave it to dry. If they've not
hardened enough, just leave them in their moulds a bit longer.
