Bath Bombs Chemistry: Family Science Activity Spotlight

Make bath bombs and explore the chemistry science / Hand-on STEM experiment

In this week's spotlight: a family science experiment that promises fizzy fun in the tub (or in a big bucket of hot water). Bath bombs are easy to make at home. You can mix up your own using your choice of additives with the core ingredients. But what makes a bath bomb "fizz" when it hits the water? In this science activity, students experiment with the recipe for making a bath bomb and investigate the role of corn starch and citric acid in the process. What is the chemical reaction that happens when the dried bath bomb touches the warm water? What ratio of ingredients makes the fizziest bath bomb? Mix up a few batches to find out! Once you have found your favorite formulation, you can make bath bombs to give as gifts—or just use them yourself!
