Preparation Time: 45 minutes
1 1/2 cups McKenzie's Bi-Carb Soda
1/2 cups McKenzie's Citric Acid
1 Potpourri, Lavender or Herbal Tea Bag contents (e.g. chamomile, lemon or peppermint)
24 drops Essential Oil (Lavender or Orange)
2 tsps Sweet Almond Oil (or Light Vegetable Oil)
Food Colouring (Optional)
Moulds - See Tips for options
For the base mix, sieve together the Bi-Carb Soda and the citric acid in a large mixing bowl. Add potpourri, lavender or herbal tea.
To make one bath bomb: In a small bowl, combine 6 drops of your chosen essential oil, 1/2 teaspoon of sweet almond oil and food colour until your desired colour is reached.
Take 1/2 cup of dry mix and stir in the oil mixture slowly so things don't start fizzing! Wearing rubber gloves, work the oil mixture into the dry ingredients with your fingertips until it stays compressed when squeezed.
Wipe a little sweet almond oil inside the mould and fill with the mixture, packing in firmly.
Repeat from Step 2 to make your other bath bombs. Leave to set for 24-36 hours before removing from mould.
You can purchase moulds from craft shops or you can use jelly moulds, decorative ice cube containers, muffin tins or any plastic container that will hold its shape. The simpler the shape of the mould, the easier it will be to remove the bath bomb.
Be creative with colours, combine red and yellow food colouring for an orange bath bomb or blue with a little red for a lavender bath bomb.
Hot water activates the fizz in the bombs – cold water doesn't work.
