Bath Bomb Mix

To make your own Bath Bombs, follow the following steps - Mix 300g Sodium Bicarbonate and 100g Citric until you have a consistent texture. Always wear safety goggles/glasses and use protective gloves when soap-making.

If you're using liquid food or cosmetic/soap colours, you will need to add enough drops to get the desired colour, mixing quickly to avoid it fizzing up. If using a powdered colour, simply add a small quantity at a time and mix until you have your desired shade. Mix 10ml of either fragrance or essential oil into the mixture. Do not leave the mixture to stand or it will slowly start to set.

With a hand sprayer, spray a very small amount of water in the mixture so it can begin to hold together when lightly squeezed in your hand, it must not be too damp. You must ensure you are working the mixture all the time while doing this, it will prevent the mixture from fizzing up.

Next you need to work quickly to compress the mixture into your moulds. If you have 2 inch moulds then the mixture will make almost exactly 5 small Bath Bombs. You will need 3 moulds, without clips, in halves ready to fill. If you do not have bath bomb moulds then you can use ice-cube trays, small yogurt pots or silicone baking moulds for cupcakes.

Fill each half so they are slightly overfilled from the surface and press together for a few moments. Now remove one half of the mould being careful not to let the Bath Bomb fall out. Leave the Bath Bombs in the remaining half to set for 20-30 minutes. After 20-30 minutes they should be quite hard. If they are, remove the Bath Bomb from the mould and leave it to dry. If they've not hardened enough, just leave them in their moulds a little longer and test again.

You can now watch your marvellous creations fizz away!
