The first time I made them they were a complete disaster as I added too much water which meant they started reacting and so I had a fizzy mess rather than bath bombs!
I recommend getting moulds as they make the best bombs. If you don’t use moulds you can make them by squishing the powder really hard into small orbs. When doing this opt for a drier powder rather than wet and let them dry for at least 24 hours.
Flower Petal Bath Bomb Recipe
Put all the dry ingredients except the citric acid into your food processor and whizz on fast to combine. Mix 1 tsp water, oil and essential oil together and slowly pour into the dry ingredients while you have the motor on.
You should have a powder which when you squeeze really hard will compact. If not you need to add another teaspoon of water. It might seem dry but you need to keep it as dry as possible so that the powders don’t react.
Add the citric acid and whizz to combine.
Pour into a bowl and add flower petals.
Now squeeze the powder really hard with your hands until it compacts then place on a kitchen towel to dry for 24 hours. Or put in bath bomb moulds you can buy at craft stores. Store in an air-tight container.
*You can buy citric acid in the bakery aisle of most supermarkets.
**Instead of almond oil you can use other light oils like jojoba, olive or sunflower.
***You can buy flower petals at some organic grocery stores, or else replace with dried flower petals or better yet pick your own.
