how to make bath bombs


About this activity:
This is a fun activity to do with kids and if yours are anything like my 6 year old who wants to be a scientist, they’ll love mixing up this “potion” in the kitchen.  You’ll not only have fun making them, but you’ll also know exactly what you’re putting in the bath!  No nasties here.

What you need before you get started:
1 ½ cups bicarbonate soda (grocery store)
½ cup citric acid powder (grocery store or chemist)
Sweet almond oil (chemist)
An essential oil such as peppermint, lavender or your favourite blend
Herbal teabags (chamomile, lemon, rosehip) or dried flowers
Food colouring (optional)
Sieve
Rubber gloves (to stop the food colouring from staining fingers)
Silicone ice-cube tray with fun shapes – mine is from Ikea but you can get them elsewhere too

How to make it:
For the bath bomb base: In a large bowl sift the bicarb soda and cirtric acid to ensure no lumps. 

Let’s start customising: you can make a variety of different smelling bath bombs and the easiest way to differentiate them is by the food colouring you use.  From the bath bomb base you’ll get approximately 2-4 batches of different bath bombs, dependant on the size of your ice-cube tray moulds!

In a separate bowl add ½ cup of your bath bomb base.  To this you’re going to add any other dry ingredients you want to use such as herbal teas, pot pourri and dried flowers such as rose petals or pot pourri.  Be as creative here as you like. My son doesn’t like “floaties” in his bath, so we limited our additions to fine chamomile tea rather than flower petals which will unfurl and increase once added to warm bath water.

In a separate small mixing bowl or measuring cup add ½ teaspoon of almond oil, a few drops of your desired food colouring (if you only have a couple of colours you can consider letting the kids mix the colours to make a third!) and a few drops of your chosen essential oil.  Mix them well so that they bond.  Now you’re going to add your wet ingredients to your dry ones and mix them quickly so that the bicarb and citric acid don’t fix too much.  You want to save some of that fizz for the bath!


I had to help my kiddo with the mixing part to make sure that the small amount of wet ingredients were thoroughly combined with the dry ingredients so that the bath bombs set properly.  Otherwise you’re going to end up with crumbly bath bombs that aren’t solid.


Once you’ve mixed it thoroughly, you’re going to start filling your moulds.  The trick here is to compact them down into the mould with the back of a teaspoon as you go and when you think you’ve reached the top use your fingers to press the mixture down into the moulds even more.  You’ll get quite a bit in each shaped hole. 



Tip: if they’re not squished down properly, they’ll come out in pieces rather than a solid shape.

Depending on the weather and humidity in the air your bath bombs will take 24-48 hours to thoroughly dry.  To get them out, you just flip your ice-cube tray upside down and gently push each bath bomb out of its hole onto a paper towel.


The bath bomb base (of bicarb and citric acid) can be stored in an airtight container if you find that you only use half a batch at a time – like we do.  Then you’ve got it sitting there ready for the next batch.

I hope you enjoy making your own bath bombs in different colours, shapes and scents just as much as you'll enjoy using them.
