Place the shampoo in a measuring jug or bowl.

You can use unscented shampoo and create your own scent with different kinds of essential oil, but I used blueberry scented shampoo because it smelled so good.

Crumble your soap in to a bowl. I find it easier to scrape down the soap with a knife, so that it crumbles, rather than grating it. Be careful if you do use a knife though!

Add the soap to the shampoo little by little. Stir it in to the shampoo until is dissolves.

If the mixture becomes too thick, add a few tablespoons of water to help you dissolve the soap. Add your essential oils and mix together.

Add some glitter to your bubble bath. Normal glitter may be a little to heavy and scratch in the bath, so it's best to use body glitter.

Mix it all together and watch as the glitter swirls around.

Fill your container half full with the shampoo mixture, top of the other half with water and then shake together well. All done!
