Cool Bath Bomb Experiment!

 In our science elective, we learnt how to make bath bombs for mothers day. But how do bath bombs react? When a bath bomb comes in contact with water, the baking soda and citric acid react to make carbon dioxide bubbles. This is an acid–base reaction, where baking soda (also called sodium bicarbonate) is a weak base and citric acid is a weak acid. We had lots of fun making our bath bombs, and my mum loved hers! Here are some photos on how they turned out below!. Here is the recipe for the bath bombs if you would like to make them yourself!

Bath Bomb Recipe What you will need: (dry) - 1 cup of baking soda 1/2 cup of citric acid  1/2 cup of epsom salt (or any salt but epson is best) (wet) - 1 tsp of water 1 tsp of essential oil 3 tsp of olive oil / coconut oil / Almond oil 2-3 drops of food coloring  Measure out and whisk together your dry ingredients in a large bowl. Next, in a small cup, mix together the wet ingredients. This is also where you’ll add the essential oils.  The next step is very important. Add the wet ingredients to the dry ingredients. You’ll want to do this very slowly, adding little drops at a time while mixing. The citric acid is what causes the bath bombs to fizz when it comes into contact with water. Adding the wet ingredients slowly minimizes this affect. Then, firmly press the mixture into the mould.  Let the bath bombs dry for at least 24 hours.
