what makes a bath bomb fizz
Have you ever had a refreshing bath with bubbles or bath salts? What if you could use chemistry to create a bath-time treat that incorporated both fizzing bubbles and soothing salts? Such a combination does exist, and it's called a bath bomb. If you have never experienced one, these "bombs" become fizzy when they touch the water. Why? It is due to a chemical reaction taking place between different ingredients within the bath bomb. Many bath bombs contain citric acid, as found in citrus fruits, and sodium bicarbonate, which is a weak base. The dry chemicals are stable, but in water, they react together to produce carbon dioxide bubbles (fizz) and, as a by-product, sodium citrate salt.
