Make your own Bath bombs with just 4 basic ingredients! Oodles of fun to create & they make ideal gifts for friends & family
To make them we used
150g Bicarbonate of soda (from a baking section of a supermarket)
50g Citric Acid powder (bought cheaply from a local chemist)
5ml of essential oil (we used lavender)
Water (in a clean spray bottle)
Optional - Few drops of food colouring (we added red)
We started by adding the citric acid & bicarbonate of soda to a bowl & mixing them together.
To add some colour we added a few drops of red food colouring & mixed well into the powdered mixture with our hands until there was an even pink colour. You have to act fairly fast after adding the liquid food colouring to prevent the mixture fizzing!
Again you have to act fairly quickly with this next step to prevent the fizzing effect. We added a few drops of lavender oil & were then ready to spray the water.
We did this a few sprays at a time, constantly stirring the ingredients until the mixture began to bind together & hold its shape when squeezed in our hands.
When the mixture did this we added it to our chosen molds, pressing it down firmly. We probably added a little too much water, but the bath bombs turned out fine, they just started to fizz a wee bit when placed in the molds. Again you have to act fairly quickly before the mixture starts to set.
We had planned to use these flexible silicone molds, but realised when we pressed the mixture into them the bath bombs lost their shape, so we ended up using solid molds to create our heart shapes.
As you can see our mixture made 6 small bath bombs. We left them for about 10 mins before gently removing them from the molds.
Once they were out we *had* to add one to a bowl of water straight away to check that they worked... that's why only 5 appear in the pic below!
We packaged them up in gift bags & added heart gift tags ready to give to friends on Valentine's Day.
Of course we've since made more. Not only were these fun to make but they're also great for exploring a little science too.
