What Causes Bath Bombs To Fizz?

What Causes Bath Bombs To Fizz?

Have you ever wondered why bath bombs fizz when added to water? Theres something so satisfying about watching the bath bomb fizz and dissolve, leaving you with a luxurious and relaxing bath. But whats the science behind these fizzy bath bombs?

Bath bombs are made of a combination of ingredients including sodium bicarbonate, citric acid. When these 2 ingredients come into contact with water, they react to create a fizzy reaction. The combination of sodium bicarbonate and citric acid produces a reaction known as an acid-base reaction. This reaction creates carbon dioxide gas, which is what causes the fizzing. One without the other will not cause any reaction.

The fizzing sensation that bath bombs create is also a result of the added fragrances and essential oils. These ingredients give the bath bomb a lovely aroma, but they also help to activate the fizzing reaction. Fragrances and essential oils are hydroscopic, which means they absorb moisture from the air. This causes the bath bomb to react faster with the water.

So there you have it!
