Our Bath Bomb Making Starter Kit contains: (makes 20 small bath bombs)

- 1 x 50 ml Fragrance Oil
- 1 x 50 ml red water-based colour
- 1 x 50ml blue water-based colour
- 1 x 50ml yellow water-based colour
- 1 x small bath bomb mould
You will need:
- Sodium Bicarbonate
- Citric Acid
- Your chosen Fragrance Oil
- Your choice of water-based colour/s
- Bath bomb mould/s
- A mixing tub for your ingredients
- Disposable gloves for when you are mixing
Step By Step Guide:
Step 1 – weighing your ingredients
- Mix 2-parts of sodium bicarbonate to 1-part citric acid (for instance you will need 500g of sodium bicarbonate to 250g of citric acid) into a large mixing bowl. It’s good practice to set aside some extra in a separate bowl in case you add too much water.
Step 2 – colour & fragrance your mixture/s
- - In a separate bowl, mix your liquids. We recommend no more than 20ml per 1KG of mixture of fragrance oil, a few drops of colour will be enough to begin with. Make sure there isn’t too much liquid, or your dry mixture will just fizz.
- - Once your mixture is thoroughly mixed, slowly add your liquids; be careful not to add too much, to avoid your mixture getting too wet. It is difficult to get deep colours such as purple or pink, so try not over-do it. Your colour will foam a little & “ball up” when you try to blend it in, we recommend squashing the little balls against the side of the bowl with the back of a spoon & continue mixing to evenly distribute the colour.
Step 3 – prepare for packing in to moulds
Your mixture should still be powdery when you move it about with your hand or spoon, but when you grab a hand full & squeeze, it should stay packed together. A good test of this is to drop your lump of squeezed mix into your bowl. If it breaks apart completely it needs more liquid; either water-based colour or water, if the mixture is too soggy, add more bicarb and citric to dry it out.
Step 4 – packing in to moulds
- Once you are happy with the bath bomb mixture consistency, spoon the mixture into the moulds & pack tightly until both cavities are overfilled. Carefully push the two halves together & squeeze firmly.
- Remove the top half - place a sheet of cellophane in your palm and turn the unmoulded half onto your palm. You should then be able to easily remove the other half of the mould. Place the bomb gently on a clean, dry surface & leave to dry overnight.
Step 5 – the finished result
- - You should now have a variety of bath bombs ready to pop in the bath!
- - Well done & enjoy!
