Making Homemade Bath Bombs
IntroductionHave you ever had a refreshing bath using a bath bomb? It can be quite the relaxing experience, especially if your bath bomb has a nice fragrance or includes some bath salts. Have you ever wondered what causes a bath bomb to become so fizzy when it touches the water in the bathtub? It is due to a chemical reaction taking place between different ingredients within the bath bomb. In this activity, you will get to make your own homemade bath bombs and explore how changing the amounts of the different ingredients affects how fizzy the bath bombs end up being when you toss them in the bath. You can use your perfected method to create some super satisfying bath bombs!
