DIY bath bombs

Supplies:

• 1 1/2 cups bicarbonate of soda
• 1/2 cup citric acid powder (use fine grade, available from chemists or pool supply shops)
• Sieve
• Potpourri or herbal teabags such as chamomile, lemon, rosehip or peppermint
• An essential oil such as peppermint, lavender, geranium
• Sweet almond oil (from chemists)
• Food colouring
• Rubber gloves
• Moulds from craft shops

Step 1

To make the base mix: sieve the bicarb soda and citric acid powder into a large dry mixing bowl. This will make enough for four bath bombs.

Step 2

To make one bath bomb, transfer 1/2 cup of the base mix into a medium bowl and stir in the contents of a herbal teabag or other dry ingredient such as potpourri. Set aside.

Step 3

In a small bowl, combine 6 drops of essential oil of your choice, 1/2 teaspoon of sweet almond oil and 8 to 12 drops of food colouring – or until your desired colour is reached.

Pour this mixture into the bowl containing the 1/2 cup of base mix and stir quickly with a teaspoon so things don’t start fizzing!

Step 4

Wearing rubber gloves, continue to combine the ingredients with your fingertips until it starts to clump together when compressed in your hand. It’s essential you do this with your fingertips, not a spoon, so the liquid is distributed evenly. The mix is now ready to go into a mould.

Step 5

Wipe a little sweet almond oil inside the mould.

Fill the mould with the mixture, packing it in firmly.

Make the other bath bombs with the remaining mixture, working with 1/2 cup at a time.

Leave the bath bombs in their moulds to set for at least 24 hours (36 hours is even better).

After they have set, turn each mould over and bang it firmly once on a flat surface, then gently ease out the bath bombs

Tips

• According to aromatherapy, different essential oils have different effects – lavender brings a sense of calm and comfort; peppermint re-energises the body and clears the mind; and geranium uplifts both mind and spirit.
• To make sure your bath bombs are easy to remove, stick to simple moulds such as ball, heart and star shapes.
• To give your bombs a pretty, textured look, sprinkle extra herbal tea or potpourri into the moulds before you press in the mix.
• Wrap individual bath bombs in clear cellophane and tie with a pretty ribbon to give as gifts. Craft supply shops also sell various vessels such as wooden boxes that you can place the bath bombs in cushioned with raffia. You can also buy decorative noodle boxes from $2 shops that make a cute gift wrapping idea.
• Remember, hot water activates the fizz in the bombs – cold water doesn’t work.
